Hi, I'm trying to wrap my head around the best way to setup our new DR ASA. Currently the production server environment and the DR side will use the same subnet. We have 7 offices that connect to this production, but will need to be able to connect to the DR side in case of a failover. Currently they are all setup over a WAN via site to site VPN.
Production 172.26.0.0/16
DR 172.26.0.0/16
Main Office 172.26.42.0
Field Offices 172.16.88.0 - Each of the 6 networks has their own portion of the subnet.
