port 80 not working trough nat
Posted on 2013-06-11
we have a network from 192.168.0.0-192.168.15.254, where the router 192.168.0.20 have a connection trough point to point connection to another network of a different company where it connects to their network trough the ip 10.10.120.253 and in the other en is the 10.10.120.254.
so in the other network they have one more router where it connects to their internal network to the network 10.20.x.x, and they have made a nat to port 80 where if I put the IP 10.10.120.254 it should connect to their webserver.
But the problem is when I try to connect to port 80 it doesnt connects, but I can ping both ip addresses the 10.10.120.254 and the 10.20.x.x
I tried to understand what can be the problem as if I put a router that is not connected to my network I can open the website trough port 80, but when I put the connection trough the network I cant open it...
Please help as I dont have more clues...By the way the hardware of routers is CISCO.
