I have a problem with a VPN redundancy link. In my infraestructure i have one dedicate link for a provider this link is filter by a FW-A on interface outside, we need a redundacy link this link are made by VPN on FWB that connect with FWA on inside interface, the problem is that; in dedicate link i apply a static NAT with 192.168.20.20 that maped real address on Outside FW-A (inside,outside) 192.168.20.20 X.X.X.X , but when the traffic switch to VPN the traffic arrive to FW-A on interface VPN . My question is that i can appli a static NAT like (inside,vpn) 192.168.20.20 with the same ip nat that i asing to dedicate link. Or if i can translate the ip in the FWB where i make the VPN Tunnel. In less words i need keep the IP NAT 192.168.20.20 for the connection between the provider.
