Ok. Here is my dilemma. I have a WRT54G v4 loaded with V23 of DD-WRT. I have a Windows XP computer (192.168.1.101) accepting incoming VPN connections. I have the router configured to forward port 1723 to that computer, and I have the PPTP passthrough enabled. I am able to connect to and authenticate with the VPN server from outside the network without a problem, but for some reason I cannot ping the server itself or the other machines on my network. The VPN assigns the remote computer an IP of 192.168.1.112-115, so it should be able to ping the LAN addresses 192.168.1.100-105 but it cannot. I can connect to the router at 192.168.1.1 and go into the router configuration, but it just seems that I cannot get to anything past the router. I am probably missing some small bit of configuration here. I had the VPN working perfectly with the Linksys firmware and it just hasn't worked since I upgraded to DD-WRT. Please help!! Thanks!!
