RE: [FW1] LAN to LAN VPN with same IP scheme



Rodney,
This would depend on how you have the LANs segmented.  If you have a
10.x.x.x/8 on either side, then the VPN will not work.  The client will
assume that the host is on it's local segment.  If, however, you are
segmented off to a class B or C, and the LANs are different segments of
those networks (e.g.. network 1 = 10.1.x.x/16---network 2 = 10.2.x.x/16),
then you should be able to tell your gateways that network 2 is on the other
side of the gateway(firewall).

Hope this helps!

Subject: [FW1] LAN to LAN VPN with same IP scheme



Can anyone tell me how you would configure two LAN's to communicate via VPN
when each lan has the same network numbers?

For example, network 1 is a 10.x.x.x network, and so is network 2 -
therefore theoretically having duplicate IP addresses.  How does the client
know when to initiate a SecuRemote connection if it's destination address is
the same as an address on the local LAN?
