We have 2 offices. Head office and a satelite office.
Each site has a router and an internal PIX firewall.
The satelite office has a point to point link back to headquarters and will be used for all connectivity, as head quarters has a very large internet connection.
In addition to this the satellite office has 2 bonded ADSL lines for failover should the primary point to point link fail.
My question is how to connect the 2 sites. Should each end of the point to point link connect into the routers at each site?
This is not really routing as they could see each other at layer 2 so I am confused what the config should look like on each router. Do I simply configure the WAN site of the Satellite office in say one private subnet and the WAN site of HQ in the same subnet and run a VPN across this link and that is it?
The satellite office needs to be able to reach the NAT'd internal addresses at HQ.
Any pointers on method/config greatly appreciated.
