2. Setup VPN in branch office B
Be very careful about the remote IP address in branch office B, because for systems behind branch office B
want to systems behind branch office A and headquarter, we have to specify these two segments in Remote
section. However if we include these two segments in one rule, the LAN segment of branch office B will be
also included in this single rule, which means intercommunication inside branch office B will run into VPN
tunnel. To avoid such situation, we need two separate rules to cover the LAN segment of branch office A and
headquarter.
This rule is for branch office B to access headquarter's LAN and Branch A's LAN.
