Below is my network set up.
Firewall----VPNRouter(having 1 interface)
I would wish to achieve a site to site VPN from the VPNRouter connected to the firewall in Site 1 to the VPN Router in the site 2.
If you could notice i have only one interface for the VPNRouter(Site 1) and so the traffic from the PC in the Site 1 LAN when trying to establish connectivity to the servers in the Site 2 when going to the second phase(with the help of the interesting traffic) needs to do both encryption as well as routing through the same available single interface only.Is this possible.
Am sure the first phase would happen, but when going to the second phase the interesting traffic has to go from the PC to Firewall to VPNRouter(get encrypted and as well route the traffic to the same Firewall interface again) to the InternetRouter and to the Site 2 VPN Router.So is that second phase possible?
Kindly let me know if i can go for such a solution and is it possible.
