Hi All, I'm currently looking to see if strongSwan and route message straight to a PPP serial link. The idea is that we run strongswan in user space, the traffic routes through the IP stack into strongswan and goes directly to the serial device to a second ppp device (where it is converted back to IP) without going back down into the IP stack.
IP traffic --> Ethernet --> IP stack --> StrongSwan --> serial connection to second machine --> IP Stack --> Ethernet Essentially I'm trying to ensure that the decrypted traffic doesn't go back down the IP stack to the serial device as we need to assure that the decrypted traffic can never pass through the same IP stack as the encrypted traffic, thus providing a definitive separation of traffic paths. Any thoughts would be greatly received. Richard
