RE: VPN between multiple LANs

Ok, thanks for the information...
One other question...

If you use the same IP for all cipe adapters, what do you route by?

Assuming the gateway in LAN3 is 192.168.103.250, you will get a default routing when you start the cipe tunnel in LAN1 like this:
192.168.103.250/255.255.255.255 -> cipcb3

Now you have to setup the routing to 192.168.103.0/255.255.255.0
Do you route through cipcb3 (device) or through 192.168.103.250(address)? Technically both work - is there a reason why one of them
is better than the other?

Thanks,

MARK
