VPN - Client LAN and company LAN on same address schema

Post by SmltIEE » Fri, 24 Oct 2008 04:00:09


My company uses the default 192.168.1.0 255.255.255.0 scheme for our internal
LAN.

We have a VPN setup that gives VPN users connecting an IP address between
192.168.1.20 - 192.168.1.25

Of course, most home users have the 192 network as their default as well, so
when they connect to our VPN and try to send packets for our server of
192.169.1.2, their router see's the destination IP and does not forward it
out to the VPN.

I know having the user change their network to something else, such as the
200 network will solve the problem, but I am hesitant on having users jump
into their routers. Is there anything I can do on my end aside from
completely changing the companies internal IP's scheme to allow VPN users to
connect?

range or subnet for peer to peer VPN. For example, in your case, you can use
IP 172.16.5.1 for the VPN host and 172.16.5.2 for ...

No. Using the default range at work was a dumb idea. Don't compound the
mistake. Just move it and be done with it.
