WRT54G WAN connections won't talk to each other

    I setup my 54G V6 recently with my Laptop and Desktop connected to the WAN of the 54G via DHCP. Each computer connects to the wireless network and internet great. My problem is I cannot get the WAN side computers to communicate with each other via NETBIOS. :mad: Just for grins, I configured the 54G to start assigning ips at From (Win2K) i can ping (XP PRO) but not visa versa. I have firewall running on both computers, but i do not see any warning messages, on either computer, about some unknow application/computer trying to access the firewall. I configured my firewall to allow connect to ip range of the WAN. My question is: is there something in the 54G config that could prevent computers on the WAN from communicating with each other?

    Thanks for your help:) Vic

    When you say WAN I think you mean LAN, and I think your problem is Windows not the router - have you run the windows wizard on each machine to configure local networking?

    Turn off ALL firewalls (MS built-in and other you may have) on your 2 Win computers completely, and then retry the ping and connections. If that works, you may have to "allow icmp" and other ports/protocols in your Win firewalls.

    WAN = Wide Area Network (for all practical purposes, the internet side), i.e. devices reachable via the WAN port of the WRT
    LAN = Local Area Network, your private network (192.168.x.x or other private net addresses), i.e., devices plugged into the LAN ports of the WRT or connected via wireless.
