Maybe anyone knows a soultion for the following problem:
I want to establish a VPN between a headquarter and 2 offices (3 different IP subnets). Each location uses a zywall as internet router and firewall.
First, obviously it's impossible to create 2 VPN rules at the headquarter, each of them connecting to one office, because the local subnets of the 2 rules would overlap.
On the other side, when I share one VPN rule at the headquarter for both clients, using 0.0.0.0 for the client IP adress (and vice versa) as it's described in the zywall documentation, it's only possible to initiate the connection from the client side. This doesn't cover my needs. I need to initiate the connection from both sides!
So, are there any other possibilities to master such a scenario with 3 zywalls?
Any help would be greatly appreciated, best regards, Gert
