I have two networks to connect via VPN as of this picture:
The rules are:
Client on LAN A must be able to connect to server on LAN C
Making a VPN between Firewall A and Firewall B is not a problem
Client must not connect to any host on LAN B, except for the outside interface of Firewall C.
How can I setup such a system, considering that I have control on all the three firewalls?
I've thought to make a VPN between Firewall A and B, then a VLAN between Firewall B and Firewall C.
Is there any better way to do that?
