I read that version 7.x allows the PIX to route back over the same interface, unlike the previous versions. Am I understanding this correctly that with this feature I could now do this:
Site A: Central Office, PIX running 7.x Site B: Remote Office, PIX connected to Site A via site to site VPN Client PC: connects to Site A from home internet connection via Cisco VPN client
Would the client PC be able to establish a VPN connection to Site A, and actually be able to traverse over to Site B, all while Sites A and B have a site to site VPN running? If yes, does the PIX version/model matter at Site B(i.e. could a 501 handle this scenario if it was in place at Site B)?
