VPN

We have several networks behind different IP Sec VPN:s and they need to communicate. How is this set up?

Network 1. 192.168.0.0/24 (connected on IP Sec VPN)
Network 2. 192.168.100.0/24 (m0n0wall network)
Network 3. 10.230.0.0/24 (connected on IP Sec VPN)

The users on Network 3 would need to connect to the ones on network 1, but currently they cannot.
From the Network 2, both other networks can be reached ok.

Best regards,

It depends on the firewalls that you have in network 1 and network 3, probably a missing VPN policy.

Hi THG,

Not likely to be that cause. We did use a different firewall before and had no problems with this and exact same configuration.

I would check routing tables, VPN policies and/or firewall rules. There is no VPN policies in m0n0wall, only firewall rules. In other firewalls, you probably need to set up a policy for each network.

By default, IPsec is only a single hop VPN.  Ideally, you need a tunnel between networks 1 and 3.  If you want to route through network 2, you need summery routes that make sense.  I would go with the third tunnel.
