we have a remote office that is connected to our network with a laser brigde, this bridge transport severals vlans as a trunk.
One of the laser is now out of service and considerede that they're are really expensive we want to replace this connection with a vpn.
In our head office we have a cisco asa cluster in failover and now we bought a new cisco asa for the branch office.
On the remote office we have severals vlan that should be connected with the vlans in the head office and we want to avoid to change the ip addressing.
To resume, I need to connect 2 offices that since now were connected at Layer2 with at bridge wireless trunk with a new vpn on cisco ASA,without having to change the ip addresses in the remote office so that a pc in the remote office on vlan10 with address 10.0.0.10 should be able to contact a server in the head office in vlan10 with ip address 10.0.0.1.
Is it this scenario possible?
Who's Ricardo? ;-)
The way to solve the overlapping issue, is to configure NAT through the tunnel.
The idea is to NAT on both sides, so that each other will think that the remote VLAN is a different subnet.
In this way you can have communication through the tunnel without overlapping problems.
