Cisco Routers :: Does RV042 Router / Firewall Support Port Forwarding From Internet

Aug 5, 2011

I am using an RV042 router/firewall -- firmware v1.3.13.02-tm -- connected to a cable modem.I have one public address (WAN1) assigned by my ISP's DHCP server.All my machines on the LAN have static IPs.  (RV042 DHCP Server is disabled.)I have set up port (80) forwarding to 192.168.1.101 The HTTP port forwarding does work if an http client on the LAN sends a request to http://<public-ip>:80But I cannot get a response if I send a request to  http://<public-ip>:80 from a machine on the WAN.
 
I  did configure Access Rules to allow http traffic (and then tried to  allow *all* traffic) between a single IP on the WAN and 192.168.1.101 The  incoming log table shows a connection is made from the http client on the internet to the correct http server on the LAN, but there is no resonse  from the LAN to the remote client.Is my configuration the problem, or is this feature not supported by the RV042 router? Could my cable modem be blocking outbound traffic?

Cisco Routers :: RV042 V3 - Port Forwarding And Firewall Rules On WAN 2

Oct 13, 2011

I have a new (about 4 months old) RV042 V3 4.0.0.07 firmware that I am trying to use in fail over mode.  I have a SOHO and I normally use cable Internet connection.  It is quite fast (15 megabit), but not super reliable.  I have added DSL (3.3 megabit) which is five nines (supposedly) but not so quick. 
 
I have a Westell 7500 wireless DSL modem located in the basement, where the telephone lines enter the building.  This gives me a wireless link to the second floor server room through  a wireless router that connects to WAN 2 of the RV042.   The cable modem is in the server room and connects directly to the WAN 1 of the RV042.  The cable works, but when it goes down, the DSL link comes up but does not allow Internet traffic.  The RV042 is set up as a Bridge and I have set up port forwarding to get the cable to work and used similar firewall commands to route the traffic if the router switched over.  I suspect that the problem is in the port forwarding (port 80) or the firewall rules(which are pretty simple) because everything looks like it switches over, but it just doesn't work on WAN2.

Cisco Routers :: RV042 Port Forwarding Stops Working When Firewall Is Enabled

Jun 4, 2013

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.

Linksys Wired Router :: RV042 Port Forwarding And Firewall Rules?

Oct 31, 2011

I have a system with a RV042 managing the internet connection.Behind the RV042 I have an e-mail server and a development machine that I access through SSH.My problem is that if I forward port 25 to my internal e-mail server it bypasses the firewall rules.I have an external vires and spam scan host that is the only one I should accept incoming email from - but it seems that whenever you add a portforward then it bypasses the firewall rules.

Cisco Routers :: RV042 - Port Forwarding Using Both WAN 1 And 2

Apr 19, 2013

Currently I have the RV042 router working in a dual WAN set up, it is configured to accept connections on numbers of ports like 80,443, 25 and forward them to a local ip.

The problem is this only works with WAN1. Is it even possible to forward ports for connections coming in over WAN2?

Cisco Routers :: RV042 V3 And SBS 2003 RWW - Why To Configure For Port Forwarding

Sep 14, 2011

I have tried replacing a loaner RV082 V2 with an RV042 V3 router with firmware 4.0.4.02. All worked well, including the site to site VPN. However, in spite of the fact that I have ports 443 and 4125 forwarded to the server (192.168.2.10), we are unable to connect via RWW. There is no such problem with the RV082. What is different with the way we configure these V3 routers for port forwarding?

Cisco Routers :: RV016 / RV042 / RV082 Internal Port Forwarding?

May 16, 2012

I'd like to setup a WCCP in those routers, but as I read, it's not possible.
 
Another way to circumvent this limitation is to foward a request to the router from the LAN port 80 to a LAN IP, something like:
 
LAN 1 192.168.1.100:80 -> router -> LAN 2 192.168.1.101:80

Cisco Routers :: RV042 Can't Get Forwarding / Firewall And Client To Gateway VPN

Jun 9, 2012

I'm trying to set up a RV042 to do the following:
 
1) Block all WAN connections, except for:

2) Allow all port 80 connections, and forward to 10.4.20.60

3) Allow all port 443 connections, and forward to 10.4.20.60

4) Allow port 22 connections from specific IP addresses, and forward to 10.4.20.60

5) After a remote client has connected using Client to Gateway VPN, allow that remote client to access anything on the LAN
 
I'm able to do #1-4 above, but I can't get #5 to work. Or I can get #5 to work, but can't implement the restrictions I need in #1-4. Attached are some relevant screenshots. I think the problem is that I have Forwarding rules set up that require me to have a firewall rule to Deny All Traffic from WAN1 (unless I'm specifically allowing it). In the Access Rules screenshot, rule #6 is the problem. If I enable it (thereby denying all WAN1 traffic), then VPN clinents can't access anything on the LAN. However if disable this rule, VPN clinents can access anything on the LAN, but the firewall also opens up all outside connections to SSH, since that's set up in the Forwarding rules. I would have thought that once a remote client is connected using client to gateway VPN, then that client is considered to be on the LAN, as far as the firewall is concerned. Thus a firewall rule (like #6) that is specified for WAN1 shouldn't effect remote VPN clients.

Cisco Routers :: RV215W Router Port Forwarding Not Working?

May 11, 2013

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.

Cisco Routers :: RV220W Find Router That Can Do Port Forwarding To Other Subnets

Mar 31, 2013

I'm trying to find a router that can do port forwarding to other subnets. My current linksys has IP of 192.168.1.1, and only allows me to port forward to 192.168.1.x, but I need to forward to 2.x, 3.x, 4.x
 
I can see how to do this on the RV215W through the online emulator, but Cisco suggested I use the RV220W. Looking through the device emulator, I can't seem to figure out how I would set it up.

Cisco Routers :: RV042G - Port Forwarding To 2 Different Destinations Based On Incoming Wan Port

Apr 22, 2013

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 :-)

Cisco Firewall :: Change Default SSH Port On ASA 5505 (port Forwarding)

Dec 2, 2011

So here is my network.
 
ASA5505--->Cisco1841--->Cat2960
Code
ASA asa831-k8.bin
Cisco 1841 c1841-adventerprisek9-mz.151-4.M2.bin
Cat 2960 c2960-lanbasek9-mz.122-55.SE1.bin
 
and here is my dilemma.
 
I can SSH from the internet to my ASA on default port 22, directly to my public IP.  I can SSH from the internet to my Cisco 1841 on port 2001. I can not however, SSH to my Cat 2960.  From what i can tell, on the Cat2960 i can't change the default port 22 for SSH to different port, just like i did on the Cisco 1841.  I looked to see if I can change the default port for SSH on he ASA, it does not look like this is an option.
 
The bottom line is that i want to be able to SSH to all three devices from the internet.  I only have one public IP.  As of now, what i can do is only SSH to the ASA on default port 22 directly to the public IP and Cisco 1841 on port 2001.  It appears that changing the default SSH port on Cat 2960 is not an option.  It also appears that I can't change the default SSH port on the ASA, if i could, i would and then i should be able to SSH to the Cat 2960 on port 22. No matter what i did on the ASA, it always listens on port 22 for SSH connections.
 
show asp table socket
TCP       001f549f  <<pub IP>>:22              0.0.0.0:*               LISTEN
 
how do i make it listen on different port?
 
Here is relevent config for SSH for cisco 1841 (port forwarding)
 
ON ASA
object network ROUTER
host 10.10.1.1

D-Link DIR-655 :: Subsonic Port Forwarding / Get Machine - Port From Outside / Internet

Feb 16, 2011

I am having an issue opening a port (4040) on the 655 for my Fedora-based subsonic server.  Inside the LAN, I can see the device from other peer machines, so I am confident the port is open and listening.  However, I can't seem to get to the machine-port from outside/internet. 

I have tried Virtual Server and Port Forwarding with single port.  The server has a stactic IP which I've included in the DHCP range and outside the range.  I have a DSL connection (AT&T), modem only.  I have updated firmware.  I have exhausted the Subsonic community's knowledge, everything points to the router, but all the settings seem correct.  What am I missing?  Is if possible there is a defect in the router? (don't laugh).  Is there a way to trace a request to that port to see where it is hanging?

(yes, I've STFA, but don't know what else to do).

Cisco Routers :: RV042 Can't Open Any Port

Jan 17, 2012

I have a RV042 Dual Wan. Two internets balanced wow! who would've thought that the headaches were waiting patiently right down the corner.
 
I was working with a 2wire Gateway that came with my ISP. I was able to open the ports in order to have public access for my students and teachers to upload their work. All I had to do was to allow my server ip address to have access to different ports blocked by the ISP. I used [URL]
 
I bought the RV042 for various reasons like excellent content blocking, load balancing, quick vpn, among other. But I just can't open the port 80 while having having my two ISP connected with load balancing, not even while having only one modem connected.
 
I have resolved many issues using the protocol binding. I have tried everthing. I just don't undertand something.
 
Whenever I connect my server to my old router, "www.canyouseeme.org" tells me that my port 80 is open. Whenever I connect my servet to the RV042-DW, my port appears closed.
 
So it's not any OS issues. 
 
I've tried:
 
- To forward the TCP 80~80 port to my server static ip address... but failed

- To enable UPnP function with the same port... but failed

- To configure the port triggering with the same port.. but failed.

- To disable the firewall.. but failed.

- To use transparent bridge in the WAN1 with my 2wire Gateway... but failed

- To set up an account in DNS.ORG already had one, everythings is in green.. but failed.

- To change the configuration in my old 2Wire Gateway router to allow a DMZ zone so all ports are public... but failed.

- To assign RV042 router ip address in my old 2Wire allowing that specific address to allow certain ports to be public... but failed.
 
I have the  Firmware v4.0.4.02 from DEC/11

Cisco Routers :: Lock LAN IP To One WAN Port On RV042?

Jun 24, 2012

I'd like to use load balancing with the RV042, but I have some devices that don't react well to not always using the same outgoing port (like a credit card machine, for instance). Is it possible for me to create some "rule" with the RV042 that an internal IP address will use a certain WAN port? And if so, when that WAN port goes down will the RV042 fail-over to the other active WAN port? I was able to do this with a Xincom XC-OPG502 (which is being replaced with the RV042).
