Cisco Routers :: Configuring Port Forwarding To 443 And Having Client VPN To Work
Mar 2, 2013
I have a problem configuring port forwarding to 443 and having client VPN to work.When 443 is NOT forwarded, VPN just runs fine (QuickVPN).As soon as I enable 443, the VPN stops working. No client can connect.I have the latest 1.2.0.9 firmware.Is there a way to enable 443 and having VPN to work at the same time ? I need 443 for Exchange.

Today i installed an RV180 VPN router as replacement for a netscreen ns-5GT.Exactly the same configuration, everything works, except port forwarding from WAN to a host inside NAT.My ports are open (online port-scanner sees the ports as open), the hosts are accepting connections, but a connection can't be made.Probably a bug in the firmware.

I have a DVR machine that I've been trying to carry out port forwarding to view cameras from outside the network. It lies on 192.168.1.31. The confusing thing is the ports. The configuration on the DVR lists a device port: 8000 and a http port: 80. I am torn between which port to forward.

I have a Cisco home rack lab which is behind my ASA 5505. I use my ASA to connect to the internet. My situation is I travel a lot for work, and I am unable to do my labbing practice. I am pretty new to ASA and would like to do a port forwarding to access my access server which is connected to my Cisco routers and switches.My network topology is this: (internet)-------(ASA 5505)----------(3550)-------(CM32 Access Server)----------(Cisco Rack) This is how I setup my remote access:
Code:
ssh 0.0.0.0 0.0.0.0 outside

I've two Cisco ASA 5550 firewall. I'm don't have much knowlege on configuring this kind of firewall. I need configuring these firewall for simple NAT. I have 3 public IP address. I would like to allow server's inside of the firewall to be able to connect to internet using private address. A basic NAT. Also need to configure some port forwarding. We've bought two firewall for the Active/Active failover support. How can i configure this through ASDM? My ASDM version is 5.2.

My ISP is centurylink and I have a 660 series modem that is both a modem and a router (no wireless). Also I have a Linksys WRT54G v3 wireless router with Tomato Firmware on it. For whatever reason I can't get the port forwarding to work. Yes, I know I have to forward the ports on both and I have tried using this guideurl...Fowarding.php on the modem, with Tomato Firmware it is super simple to forward.

I have a W7 PC 64 bit system and I've been trying to port forward the port 25565 for my Minecraft server. However for some reason (even after port forwarding the right one) people still can't connect. When I check on Open Port Check Tool - Test Port Forwarding on Your Router It still says that the port 25565 is closed!I've even created an Inbound and Outbound rule in the Windows Firewall advanced settings. I use Avira Anti-vir fyi..

Edit I've found a work-around. It's on page 2: [URL]
I'm having this really weird issue with my DIR-655 revB. I have some port forwarding rules set up and externally they work fine. However, if I try connecting to my IP address using those same ports from a computer within my LAN, it won't connect.
Externally, I can ping my WAN address and connect through forwarded ports. No problems. Internally, pinging my WAN address apparently works (just now is the first time that's worked for me), however I can't access any of my computers using the WAN IP and port forwarded ports. I can access them by going directly to their hostnames or LAN IPs.
Things I've tried:
-Disabling/enabling firewalls on all computers involved
-Disabling/enabling QoS engine
-Disabling/enabling DNS relay
-Disabling/enabling Advanced DNS
-Adding custom nameservers from Google and Comodo
-Restarting computers
-Clearing DNS cache (I use a dynamic DNS name which works externally but not internally. This gets the correct IP internally and connecting directly to the IP doesn't work either.)
-Modifying the NAT Endpoint Filtering settings
I have an external DSL modem connected to the router using PPPoE if it matters.
The weird part is that it works externally but I've modified all of the values I can think of in the config with no luck. I upgraded to the DIR-655 from a DIR-615 which had all these settings in it and worked fine (until it started acting up which is why I replaced it).

I have been trying so hard to get the following ports to work:
5120 - 5300
I have looked up countless guides, and have done everything in them, I have a static IP, I used the gateway to create the port forwarding rule, AND opened the ports on the windows firewall.
Nothing works. The port remains closed, and I can't host games. My modem is an Ambit U10C037
System Specs:
OS Version: Microsoft Windows XP Professional, Service Pack 3, 32 bit
Processor: Intel Pentium III Xeon processor, x86 Family 6 Model 23 Stepping 6
Processor Count: 2

First off, my router is a D-Link DIR-655, firmware v2.07. I'm trying to port forward port 25565.
My port forward settings are this:
However, when I use this open port checker, it claims that I don't have that port open. It looks like this, without the blurred out parts:
Added note: The way I want to use it is by my IP (xxx.xxx.xxx.154:25565). I have the software installed to do so (I'm using a minecraft server, connecting through minecraft), but I can't enter my IP in the IP address field, it says that it's out of the range of the LAN.

I have a Netgear WRG614 and a Westell 610015 Modem. I need Port Forwarding. I have tried setting up a static IP then Port Forwarding but it doesn't work. I have tried port forwarding from the modem but it doesn't work. I wanna forward ports "80, 9958, and 5816". The reason is because I am gonna host a game server on my computer.

I set up my new E4200 to forward port 7300 to a computer on my LAN. I had this working on my Linksys WRT160N and copied all of the settings so they are identical to those on that router but forwarding does not work. I have tried single port forwarding, multiple port forwarding and even DMZ with the same lack of results.

IPort forwarding simply does not work with this rounter on Comcast. I called comcast to see if they were blocking ports and they insist they ARE NOT.So what can it be? Was on FIOS with their modem/router combo and port forwarding worked like a charm with them.I've tried single port forwarding, port range forwarding, yada.
I am using the correct internal IP address on the machine I want to enable port forwarding on..Latest firmware is installed 1.04 or whatever (just purchased the router and updated during the Cisco Connect install on the 29th). Guess I should go find a cheaper router that actually works...

Region : Italy
Model : TD-W8961ND
Hardware Version : V3
Firmware Version : 3.0.0 Build 120720 Rel.09287
ISP : alice
A couple of weeks ago I have bought a TD-W8961ND in replacement of my old modem/router (of another brand, to upgrade from Wireless G to N). I tried to replicate in the new router something similar to my old setup, so I programmed Virtual Servers (under the NAT menu) with the following rules: NATRules.jpg in an attempt to:
- grant access from "outside" Internet to my web server
- have a Wakeup-On-LAN from "outside" Internet ..etc.. without success. Please note that:
- I have successfully setup a DDNS server to reach my modem router from outside
- as for WOL, I defined my subnet mask as 255.255.255.128
- I have not set any other rule, nor in NAT, nor in routing or other
- I tried also with firewall disabled
- I do my testing by means of a smartphone with wireless disabled and Internet connection via mobile service provider
- Both the above mentioned functions were working with my old modem/router (and still work on LAN), and I have not changed other things (PC setup etc)

Model : TL-MR3420
Hardware Version : V2
Firmware Version : TL-MR3420_V2_121206
ISP : 3
I am using a MR3420 V2 together with a E398 modem. The connection works well, but I can't do any port forwarding (virtual server). Using another router (Tiny Dovado) with the same E398 modem works flawlessly to forward ports.

i have a WRT160N V3 and DMZ or Portforwarding dont work.i tried locally following
WAN_PC-> WAN-PORT -> WRT160N V3 -> LOCAL-PORT -> LOCAL_PC
The WAN_PC has a Static-IP 192.168.1.2, Subnet 255.255.255.0
The WAN-PORT has a Static-IP 192.168.1.1, Subnet 255.255.255.0
ON the WRT160N V3 i configured a DMZ on 192.168.0.100.and Disabled the Firewall.
On the LOCAL_PC (192.168.0.100:8888) is a Apache
So when i type 192.168.1.1:8888 on the WAN_PC i get NOOO Website from the Apache on 192.168.0.100:8888?

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'm trying to ensure I have wireless coverage in my entire house and having extreme difficulty getting all machines to play nicelyWireless modem router #1 (downstairs in my house) is connected to the ADSL line and has the following config:IP Address = 192.168.1.1 DHCP on DHCP pool 192.168.1.3-192.168.1.100 Subnet = 255.255.255.0 Wifi channel = 1 Wireless router #2 (upstairs) is connected by ethernet cable to Wireless modem router #1 and has the following config:IP Address = 192.168.1.2 DHCP off Subnet = 255.255.255.0 Wifi channel = 11 Different SSID and encryption key to Wireless modem router #1 With this configuration, I can connect to the internet via both routers and all seems to be well. Except... having established a connection through either one, my machines will only make a pretend connection with the other one. By "pretend", I mean that the (Windows) machine says it has an excellent connection to the router but can only see machines on the LAN - it cannot get to the internet even though other machines are connected through the same router to the internet.
For example, if I'm sitting next to the downstairs router and establish a connection with it, all is well. Then I move upstairs and my machine switches to the upstairs router. Signal strength will be reported as "Excellent" and I'll be able to connect to the local NAS or printer but no external devices or sites.I have tried having the same SSID and wireless configuration on both but the result was the same.Today I read the suggestion to enable the DHCP server on the 2nd router but to set it to distribute a different non-overlapping IP range (i.e. router 1 can have a pool of 192.168.1.3-192.168.1.50, and router 2 can have a pool of 192.168.1.51-192.168.1.99)

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 have done this before on this exact model about a month ago, so it's still fresh in my mind on port forwarding. (note, I'm using firmware version: 1.0.00) I am running a windows 7 computer wirelessly using this router.What I do for port forwarding is type in router IP (192.168.2.1) in internet explorer, type in "default" as username and "admin" as password. I click the "applications and gaming" link which brings me to port range forwarding.
I fill in my port info, in this case a mine craft server running on 25565. I set up two of the same ports, different names both at the same port, one running TCP and the other UDP, when it worked previously the "both" option did not work correctly. (I used to have a private network that a buddy of mine set up a while back, and I doubt he remembers what to do and I don't know where the manual is to make a new one, searching the internet sends me spam of people asking questions.)
I read somewhere it may have something to do with DHCP server settings conflicting with my IP. My IPv4 address reads 192.168.2.100, and the DHCP settings says the same.

I am having a NAT issue with my two xboxes. The router is an e1000 v2.1 firmware 2.1.02. One xbox is wired into the router and the other has a wireless adapter. The wireless xbox gets open nat automatically, while the wired one's nat is strict. If i mess with DMZ and turn UPnP off i can get the wired to be open but the wireless one to be strict. Also port forwarding does not seem to work because only one or the other xboxes will get an open NAT. I do have the the correct ports in the port triggering section set to on but that does not seem like it works.

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.

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 Cisco RVS4000 with Port 1 as a trunk connection to a Cisco SF300 switch. Port 1 on the router is configured 1untag,2tag,3tag,4ag. When connected directly to the router I can connect to the switches management IP. I would like to reach the switch remotely. I have set up DDNS and can access the router and I have have set a specific port to forward to port 80 on the switches management IP but this does not work. Should I not be able to Port Forward to the switch across VLAN 1?

Port forwarding on rv120 does not work. I have followed the workaround instructions: so i have created a firewall access rule on incoming port 21 to an internal ip address on the same port. The router has created the forwarding port rule. But port forwarding does not work. I have tried to use a custom service but nothing!
The router is reachable from wan, I can access via DNS the configuration page and I can ping the router on wan port.

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?
