Local Network Disappears when Connected to VPN

[Steve90318]

Have setup a connection to my office computer set the router to forward the ports and the connection worked fine, can connect to drives and remote desk connection etc.

Both machines are XP Professional SP1 and there are other computers Win98se on the network and these all work as well.

I then installed the same router at my home and another computer connected them together through the router and the internet and file sharing worked fine. I could then connect to the VPN but not PING or connect to the office computers.

I then unticked a box on the VPN Client called "USE DEFAULT GATEWAY ON REMOTE COMPUTER" it would then let me ping etc as normal. I also was then unable to connect any web sites until I put preffered DNS server under the VPN's TCP/IP settings for my local router.

It then let me surf the web, use the VPN but I lost the ablity to 'see' any of the other computers locally, or ping them.

Soon as I disconnect the VPN it works fine?! The thing is both networks use the same workgroups, subnet mask?, same rang of IP addresses (no duplicates across the networks though).

Shall i put them on different workgroups and subnet masks?

both networks are on 192.168.254.X as its IP range and both use 255.255.255.0 as there subnet mask? Shall I change my local (home) network subnet masks to somthing else? Any suggestions?

The first thing you should do is create different subnets. You can't have the same subnet (192.168.254.xxx) on both sides of the routers. Make one (home for example) 192.168.253.xxx. There are probably static routes to be configured on both routers but I can't check that out here at home (not able to muck around the corporate router configs). MCP
