I'm a VPN client (xp pro) connecting to WinServer2003 PPTP from behind a WRT54GP2 (voip version). When my connection is established my internet connectivity is terminated. Some net-based programs still work - those that connect direct to the box running the VPN server but I need general browsing and email stuff.
Very new to networking configuration (thankx mainly to being banished to the 'dialup only' world for the last 8 years) but from what I gather there are at least a couple options for re-enabling public internet connectivity.
I've tried the chat support with linksys...MTU to 1400...port forwarded 1723, 500, 47. PPTP pass thru enabled. Then the conclusion:
[tech]: Basically, the reason why you are being disconnected with the internet connection is that the computer is getting a different IP Address segment when it is connected to the VPN. You may try contacting AT&T and ask if they do have a firmware update for the device.
Suggest i contact the VoIP vendor for firmware update??!! That doesn't inspire a great deal of confidence. (did i mention i was new to this network stuff?)
Can someone step-by-step me thru tunnel splitting?
