Re: Hosted VPN Solution - any ideas welcome!

I think ayroba alluded to a broadcast domain, whereas any member of a VLAN should be able to ping each other within the same VLAN if all hosts are using IP addresses from the same subnet.

There's no splitting up of a broadcast domain when it crosses a VPN tunnel AFAIK. In a tunnel, you have Network A, Network B, etc etc and a route between the two as determined by the routing table.

Right, I agree.. I think he was alluding to that too. My question was "where" that defined..? Is everything in one ISAKMP profile considered one vlan? So other profiles will create other vlans?

Ive realized that if I dont specify a router for the vlan that the IP Pool range is on, I cannot ping other hosts on the same IP pool. If I add an IP to the route-filter ACL, then I can reach other hosts. This only works with I see the router in my "router details" tab in the VPN client..

With an ISAKMP profile, you reference an ACL that the assigned interface uses to forward interesting traffic through the tunnel. This ACL can specify one host or an entire subnet.

I suppose you can trick two tunnel endpoints to act as though it's bridging interesting traffic through the tunnel by using the same subnet on both ends, but I'd think that can cause issues with ARP.
