Cisco Routers :: RV110W Port Forwarding Stops Working
Oct 25, 2011
I am using a RV110W with the latest firmware 1.0.1.6 I have some port forwarding configured, which normally work. But sometimes, all port forwarding stop working. Everything else continues working normally, just all port forwarding don't work any more. I tried disabling the port forwarding and enabling them again, this doesn't work. Also disabling the firewall completely does not work. You have to reboot the router, then everything works fine again. When I make a portscan from outside with a "fresh" started router, the forwarded ports are open. When the error occurs and I make a portscan from outside, all ports that should be open (and have been open before) are closed.

I have a RV042 router on a single WAN and an internal LAN. I have configured port forwarding as follows: HTTP[TCP/80~80]->10.0.0.6HTTPS[TCP/443~443]->10.0.0.6IMAP[TCP/143~143]->10.0.0.5IMAP SSL[TCP/993~993]->10.0.0.5SMTP SSL[TCP/587~587]->10.0.0.5
Everything works just fine when I have the firewall DISABLED. However, when I enable it the behaviour is erratic. 1 out of 10 attempts to connect to ANY port forwarded works. Almost all attempts time out. Notice that this happens even if using only the default firewall rules (which should be bypassed by the port forwarding as I read in other posts).
My second try was to create firewall rules manually, overriding the default ones. I tried adding rules from source WAN1 (where my connection is) to ANY and to SINGLE IP's on every port. Nothing seems to work.
I don't know what I'm doing wrong, this is really bugging me. I had to turn the firewall off so we can access our servers from outside the office. This shouldn't have to be done.
Just found out that my firewall is getting LOTS and LOTS of Blocked - SYN Flood entries. I think this is why we are having trouble with the firewall. Could this be the problem? I have no idea where all these SYN packets are coming from since they appear with spoofed IPs or come from different bots all over.

I installed firmware version 1.2.0.9 a couple weeks ago after seeing in the release notes that the port forwarding bug where clients would get 'no route to host' was resolved (one of the original posts found here:URL
After installing the firmware and confirming it's running I've seen no improvement. I still must reboot my router 2-3 times daily so clients can access the ports that are defined in the port forwarding module.

Here is the configuration : I newly installed for a client a RV110W (firmware 1.2.0.9) wich connect on the internet trough Dlink 320B (ppoe connexion, in France - the provider is orange). Wifi is ok, VPN is ok, wan is ok ...
But no way to make port forwarding works (form wan to lan of course). I tried to reboot the router, the modem, reseting router configuration before re-apply mine, it didn't made any change. I also tried single and range port forwarding, without any succes...

Having a problem with port forwarding on their WRT400N? I'm forwarding one service (https) and this stops working if it's not accessed after a 10 days or so. The only way to get it to work again is to reboot the router. I’m running the “latest" firmware, which is an oxymoron considering it's been over 12 MONTHS since Linksys updated the code... Which is appalling considering this appears to be their flagship wireless N router.

I just installed an RV180 at home. I can not get port forwarding to work - after reading in several forums I realize that I need a firmware 1.0.2.2 that currently is in a beta stage.

This is the RVS 4000
Firmware version 1.3.3.5
STAR 9202 Chipset
64 MB DRAM
8MB Flash
DOS, Block WAN Rq, Remote mgmt all OFF
IPSec Tunnel none used
[code].....
Every day or so the Router becomes unresponsive to the HTTP mgmt interface, as well as it no longer offers DHCP services.then this happens the only remedy is to power reboot.
Everything comes back online just fine, however, the LOGS are initilaized so no data to figure out what`s going on.My next step is to setuo a syslog server and have the logs copied out.( No, I have no Torrents running at all, but I do have several devices like AppleTV, PS3s etc that run streaming Video plus I have the SPA3102 )

RV215W router port forwarding not working.Port forwarding works for a short period of time, then stops working. Reboot router, works again for short period of time, then stops again.
I have updated firmware to latest. I had seen other similar bugs posted for 220 and I think 180, not sure if this router has similar bugs and waiting for fix release to firmware.I had recently purchased two, one deployed, will hold off on other now because of issues, and may have to move to different unit if a resolution not found this week.

The Port 80 port fowarding stops functioning after a few hours and requires the router to be rebooted to start forwarding again. The firmeware is the latest 1.0.04 Build 7. I require it to operate reliably for many days without intervention. I assume that it is a port forwarding problem because I can access the IP on my network from within my network even when I can't access it from outside my network. I am using the correct IP addresses as it sometimes works OK. A characteristic is that when I can't access the page it loads as completely blank white with no error message.

I just bought and setup a RV110W. I noticed while scanning it from the WAN side that it always has port 443 open, even when remote management and VPN access are disabled. Why is this port still open, and how do I close it? Or is this a bug in the firmware? I am using firmware version 1.1.0.9, which is the most up-to-date for this unit. Having open ports allowing unsolicited contact from the WAN side, especially inadvertant ones, is a major security hole.

I am trying to connect from the outside to a TCP server inside my lan that is listening on Port 25565. I am using a RV110W. I did the DMZ IP for it.
From the Lan I can establish a connection (even with my dynamic dns address). As I try it from the outside the server log tells me that a connection has been establishen but it shows the gateways IP. Afterwards it tells me the connection hase bin lost (Time out).
As I set Port forwarding I even cannot reach the server from the out side and lan.
I even did set up access rule WAN to Lan.

Just purchased a Cisco RV110W for our small business. We were told this was easy for us to use and secure enough for our small office and for our travelling sales staff to access our website.
We purchased 2 dedicated IP-addresses, 216.82.5.230 for access to one server, and 216.82.5.231 for access to a second server (these IP-Addresses given are just an example; not real).
These come into the single RV110W WAN port. The two servers are plugged into 2 of the 4 LAN ports.
But the WAN setup page only accepts one WAN IP-Address. So when we put in 216.82.5.230, the outside world can HTTPS into one server, but we don't know how to get them to HTTPS to the second server when the other staff uses 216.82.5.231.
In summary, how to use the RV110W admin panel to forward the HTTPS/SSL traffic from 216.82.5.230 to one server (setup internally on 192.168.10.20), and the HTTPS/SSL traffic from 216.82.5.231 to the other server (setup internally on 192.168.20.20 using the VLAN setup on this router)?

how to: port forwarding to 2 different destinations based on incoming WAN port
The default HTTP service works fine: TCP80/80-> 192.168.0.55
I have a couple of IP security camera's I'd like to be able to access remotely that also listen on port 80. I tried TCP & UDP 8009/8009-> 192.168.0.9 without any luck. Not sure how to handle the port redirects on the RV042G? Seems simple and was on the Symantec, could be user training :-)
I was able to do port redirect with the Symantec Firewall I'm replacing.

Is it possible to create a service which will forward public port 9010 to an internal IP address with port 23 ?
First of all, I do not like to open the public Telnet port to the inside so I would use another public port and second my ISP does not allow some public ports beneath port 80

I've set up port forwarding from an external port (9000) to an internal port (80) on our SRP541W, and for some reason, it's not working externally. If I access the public address from within the internal network, it works properly.

I had an old linksys router running DDWRT. I bought a new Asus RT-N16 and finally set it up. I had to just duplicate the settings by hand as you cannot back them up across different hardware models even though both are running DDWRT.
I hooked up the new router and everything was working great, until I decided to check one of my port forwards. Turns out its not working, I can't connect through my DynDNS assigned dns name. Assuming I configured something wrong, I compared the settings of the two routers. Nothing interesting, it is set up right.
From there I decided to just hook the old router up, assuming I overlooked something. So I mess around with all the cables, and then, to my surprise, IT STILL DIDN'T WORK.
A few points of interest:My Static IPS are set up right. My server has the proper IP My home IP did not change. DynDns has the right IP. I rebooted all the network equipment and server... just for the hell of it. I tried changing a port forward to point to my main PC and that failed too.

I want to setup port forwarding in my office router so that i can access my lan computer (192.168.0.122) from any where in the world through (remote desktop connection)I have (D-Link (DIR-615)) router. I went to virtual server option. then i select application name as Remote desktop then public port as (3389), protocol (both), Schedule (Always).My lan computer ip address (192.168.0.122), private port (same 3389), inbound filter (allow all). then i clicked save settings. Then the router took 20 seconds to save. then i close the browser.Then i asked my brother to connect through remote desktop connection who is on the skype and he is in different country and that time he is in office. So he put my router public ip address (xxx.xxx.xxx.xxx:3389) in this format but unable to connect.

I have a DSL modem (custom made and branded by my ISP) which is receiving a DSL stream... it has an external IP which is visible to the world, say, 11.22.33.44 ... This modem has DHCP enabled, has an internal IP for itself, which is 192.168.1.1 .. it is connected to 2 laptops via and ethernet cable .. Laptop 1 has IP 192.168.1.2, and Laptop 2 has IP 192.168.1.3 ...On Laptop 1, two applications are running, jDownloader and Media Player Classic, which have their web interfaces on ports 8765 and 13579,respectively.. I can access both of these web interfaces from Laptop 2 by opening these addresses: 192.1681.2:8765 and 192.168.1.2:13579 ... both of their web interfaces open up, meaning the web interfaces are working fine ..Moving on, I now want to access these web interfaces from outside my network as well, and so I've configured port forwarding in my DSL modem to forward all traffic on ports between 8000 and 14000 (both TCP and UDP) to IP 192.168.1.2 ... I have verified that port forwarding is working by testing it using PortForward.com's port checker tool, and this website too: Open Port Check Tool - Test Port Forwarding on Your Router When I use the website, if I'm running the applications on Laptop 2, the website reports that the port is open .. if I then close the application, the website reports the port is closed ... This makes sense as nothing is listening on my machine in the latter case .. Also, if I disable port forwarding in my modem, again, the website reports the port is closed ... so, the website's results seem to be okay ...
Despite the above tools reporting that port forwarding is working, I am unable to open the web interfaces from outside my network ... So for example, if I tried to browse 11.22.33.44:8765 or 11.22.33.44:13579, nothing opens in my browser ... But if I accessed these web server's locally from Laptop 3, by typing in 192.168.1.2:8765 or 192.168.1.2:13579, they opened ... The tools report unanimously that port forwarding is working, and yet I am unable to open the web interfaces from outside the network ..Also note that I have disabled the firewall from my computer, and have also made sure that any option in the above programs (whose web interfaces I am trying to open) that says only local connections are to be accepted, is disabled ...

I'm trying to set up a Minecraft server so I can appear to be a hero to my 8 year old son. I have to forward a port to 25565 adn I've followed all the instructions on how to do this on my netgear DGND3700v2. I've also turned off my Windows 7 firewall, but when I go to a test website, I still get a message saying the port is closed. I don't have a static IP address, is this absolutely critical or does it just mean that the boys will have to log on to a new IP address each time they want to play?

My modem/router is Riger and model is DB108-WL. I had set Port Forwarding in my modem/router configuration page using web [URL] had disable the uPNP setting in both the modem/router and camera setting page. Besides, also disable the firewall on the modem/router and on my laptop (Windows firewall and McAfee antivirus)My camera static IP address details are listed as below:
IPv4 Address: 192.168.1.8
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
Primary DNS: 192.168.1.1
Port number: 8080
I am able to access my IP Camera using local LAN network by using web [URL] but unable to access from external network WAN using internet by using web http://*External IP Address*:8080 My ISP provide a dynamic external IP address so my external IP Address will change each time I connect to internet network. To trace this, I used IPchicken website IP Chicken - Whats my IP address? ip address lookup to identify my modem/router Public IP address. I used my smartphone to access this external IP Address in order to prevent NAT Loopback issue but still can not access.
1) Do I need to have my host computer turn on at home in order for me to access the IP Camera from external WAN network which is internet from anywhere outside? Or just turn on my modem/router and IP Camera will do?
2) I had read a lot of blogs and forums from the past 2 weeks about Port Forwarding. From one of the forum, it mentioned need to setup 2 ports for Port Forwarding in order to get IP Camera access from external network. One for web interface which use port 80 and another one for video streaming which is port 1024. So, is it true for every IP Camera to configure 2 ports forwarding in order to get access from external network?
3) If I can access the IP Camera from local LAN network, does it mean my laptop Windows firewall and McAfee antivirus setting is ok for access from external network?
4)Is it a reliable method to use smartphone as a test to try out whether my setting is ok to access the IP Camera from external network? My smartphone is Android 2.3 OS and able to access the IP Camera when connected to my modem/router using WIFI (local LAN access). When key in external IP address using 3G network, it can not access.

I have issues with port forwarding. I did, but it didn't work. Then I tried different ip addresses. Now I don't know how to delete those configurations, because when I try to overwrite it says already exist. And still port forwarding is not working. I did: ip nat inside source static tcp (ip and port numbers)Our device is 1841, also we have firewall within this router. DHCP is in our 3750.

When my RV042 is accessed for long transmissions (svn check out, usually after 20 minutes ) the client receives a message "Gateway not responding, do you want to wait".
When this happens I see the following in the RV042 system log (the first 3 lines of the log below are normal):

We bought an RV042 at the end of June. It is used as a gateway and VPN router. DHCP server is disabled and all IPs are configured manually.Every once in a while (Tuesday night, then Friday night - yesterday, it has hapened once or twice before that) the router appears to restart (see log below) then comes back up with system time of Jan 01 2010. At this point the router will no longer load its configuration page (https://10.29.238.197:16443/) and VPN connection to our customer in Africa drops. However, devices behind the router can be reached and can access the internet. The only way to fix this is to power cycle the router at which point everything starts working flawlessly again.The PID VID is RV042 V03 running firmware v4.0.3.03-tm (May 12 2011 21:27:37). Our RV042 is a newer one with Cisco SMB Router branding not the older Linksys branding.
From the log when the router reboots:
Aug 12 22:38:42 2011VPN Log(g2gips0) #141: retransmitting in response to duplicate packet; already STATE_QUICK_I2Jan 1 01:00:05 2010System Logheart : System is upJan 1 01:00:13 2010System LogWAN connection is up : 10.29.238.197/255.255.255.192 gw 10.29.238.225 on eth1Jan 1 01:00:15 2010VPN Log(g2gips0) #1: [Tunnel Negotiation Info] >>> Initiator Send Main Mode 1st packet
I looked at the log more and all the usual messages assosciated with VPN being established are there - the last thing in the log before the router coming back up again is:
Jan 1 01:03:49 2010VPN Log(g2gips0) #4: [Tunnel Negotiation Info] Quick Mode Phase 2 SA Established, IPSec Tunnel ConnectedJan 1 01:03:49 2010VPN Log(g2gips0) #4: [Tunnel Negotiation Info] Quick Mode Phase 2 SA Established, IPSec Tunnel ConnectedJan 1 01:03:49 2010VPN Log(g2gips0) #4: sent QI2, IPsec SA established {ESP=>0x575a01c0 <0x6534ae4e
So it even claims the tunnel should be up but I can never reach anything on the far side.

I have RV042 and E4200 routers . I tried the manual UPnP port forwarding using Rv042 router and was succesful ( by typing 192.168.1.1 in the explorer and logged in using user name and password )
I am using a linux embedded system whose Internal IP ,Internal port are mapped .This system is connected to one of the LAN ports
I want to try auto UPnP port forwarding both for RV042 router and Linksys E4200 routers
After enabling the Upnp option only and logging out ,Can i add a port mapping entry in this router without logging in using a C++ program which runs on linux embedded system .

I have a licensing server. Other computers need to turn on a program, they send a message to the licensing server, and it responds that they have permission to run.Until today the licensing server was plugged into its own ethernet wall socket and configured with a static IP address. Today I put a router into that wall socket and now the server's plugged into the router.The router (WRT-54G) was set to the static IP - and now the internet on its network works. I set all ports to be forwarded to the server's internal IP address - and now my programs can detect and ping it. But now the server won't send back permissions to use licensed software, or even reply with a list of the software which it can license.

I am trying to run a server for minecraft, which some of you may know primarily uses Port 25565. I have tried everything that I've seen suggested. I have a Linksys WRT54GS router that I have my 2 xboxes, playstation 3, pc, and wii connected to. Now, I don't use any of these components at the same time. I had an issue with my xbox and the game "Black Ops", where my NAT type was strict, but a microsoft support technician walked me through port forwarding for the xbox, and it worked. My NAT type was displayed as "open" now. This is not the case with Port 25565 however, as even though I've port forwarded 25565 to my static IP i set up for my PC (which is my server PC), Port checking sites such as "Yougetsignal" and a couple of others are still showing no connection for the current external IP and Port 25565.
I went through ipconfig in windows "cmd" and made sure I had all the ip's and subnets and dns' and whatnot correctly entered in my routers configuration page. I went into Windows firewall and put new rules for port 25565 into incoming rules. None of this seems to work. I even shut off the firewall completely (temporarily, mind you), just to eliminate that possibility, to no avail. Still getting negative responses from these sites. I am able to log into my server myself, using "localhost" as the address, but none of my minecraft buddies can get on my server. I've also tried to use Hamachi to set up a server, which doesn't need ports to be forwarded, but although they can join my hamachi network, they can't join the server. Obviously there is more of a problem than just not being able to open ports, and I am at a loss.
Also, I am aware that my external IP, given by my ISP, will change with every disconnect and reconnect of my signal. I got my current IP address during this time and gave that to my buddies so they could join the non-hamachi network. For the Hamachi server I edited my Hamachi network IP into my server software's properties file, where as it would be left blank for my non-hamachi server.
