Hello ! Here's my problem : We have a wired BEFSR41 V3 with IP address 192.168.3.1. A DSL modem is connected to its LAN port. There is two 24-ports switches connected to the BEFSR41. To add wireless network connectivity to our new offices in the next building, I've added a 150' network cable going from one of the switch to our other office. In the new office I added a WRT54GS v7 with WAN address 192.168.3.2. Its LAN address is 192.168.30.1 with a DHCP server and WEP security. Three computers are using the WiFi connexion. It is working fine, Internet access is working fine, and all computers in the 192.168.30.0 network can ping and access any device in the 192.168.3.0 network. But the reverse is not working. From any computer in the 192.168.3.0 network, I cannot ping anything in the 192.168.30.0 network. Tried many things to get the routes working but it all failed. I'm able to ping the 192.168.3.2 (WAN address for the WRT) but cannot telnet, etc.. Any suggestion ? Thank you !
