Red face Port forwarding to second LAN router
Hi,

Using a DynDns account I am able to access my Netgear DG834GT (R1) Wireless router 'admin' web page from the Internet, by typing dns <hostname>. I get access to the web interface. If I type <hostname>:8080, which is what I configured I get nothing. Why is that ?

I then want to then access a second wired Netgear FCVS124G router (R2) and access its 'admin' web pages on port 8081, but through R1. So I added a service and a rule in the port forwarding section for R1. I also enabled R2's web interface on port 8081. If I type <hostname>:8081 I get a log entry in R1 : <date> - TCP Packet - Source:192.168.0.5,2043 Destination:217.44.239.9,8081 - [fvs124g rule match], but I dont get the web interface. Any ideas why not ?

This might help:

Routers differentiate networks, so you need to have your interfaces on each side belong to a different subnet so that the router knows how to route packets.

Reply to diff routers have diff subnets
I understand your reply. I changed R2 to be configured TCP/IP wise in the same subnet as R1 and using RIP, both routers can see each other and access everything on the LAN from either end. Internally (locally) I am really happy. Everything internally can access the web, its access from externally. All I can see is the WAN R1 router 'admin' port. If I access a R1 port forwarding port I get a rule match, but it doesnt seem to 'in Jamie Olivers' words 'pass it on'.
