I have the following scenario: Two subnets, two ipsec vpn servers using openswan. Vpn server 1 192.168.10.1,10.10.1.1 Vpn Server 2 192.168.30.1, 10.30.1.1 I can ping 192.168.10.1 -> 30.1, but cannot ping 10.10.1.1 -> 10.30/16 , but can ping from 10.30.1.10 {any system not the vpn box} to 10.10.1.1} Is this how the SA dictates the vpn or is it a routing thing. I noticed that if I ping from 10.10.1.1 to an 10.30/16 address, the packets are sent over the ipsecX but with an 192.168.10.1 as a source address. I should I see this, I thought the SA would only tunnel 10.10/16 <-> 10.30/16 traffic? Is there a way I can allow for the vpn systems to use its internal source address?
