Error http request via IPVPN

Unanswered Question
Nov 26th, 2009


I have a problem with our 2 branches accessing http port. Let's say Site B can't access the web server in Site A but Site A can access the web server in Site B. In site A we have Cisco 2811 Router and a Cisco 3560 Core Switch, on site B we have a Cisco 1841 router that is connected to ordinary switch. In both routers all ip route and network route has been properly declared. We have a Call Manager Server in site A and an IP Phone in site B can successfully connect to the CCM server. My only problem is accessing the web servers in site A.

By checking the http logs on our web servers I found out that the request from site B has reached on the web server but the reply of the web server will not reached site B.

Can you give me any help guys? All answers are highly appreciated and properly rated.

have u deployed any FW in site A ? can u try tracing the site B location IP's from Site A and check where exactly its getting dropped ?

Based on your post I suspect some kinda reverse route issue which needs to be fixed.

Hi Spremkumar,

I have done traceroutes on both sites many times now and everything are working there is no drop in packets at any sites. So sorry so ask this but what is FW?

BTW our web servers in site A requires chaching from our Proxy Server to properly and any pc's in Site B can connect to the proxy server in site A so I'm really confused why on port 80 will not work.

Hope you can help me further.
