You don't say which is which, so I'll assume 192.168.1.78 is behind 126.96.36.199 and 10.0.2.15 is behind 188.8.131.52.

You'll need to set up the public routers at both ends to forward UDP/500 and protocols 50 and 51 (just for completeness) to the OpenSWAN endpoints inside each public address. if that is the case, you can try: ipsec whack --listen ipsec auto --add connect1 ipsec auto --up connect1 Note that older versions of "addconn" acted badly with rightnexthop=%defaultroute if you Openswan 022 We Cannot Identify Ourselves With Either End Of This Connection Join Date Nov 2007 Posts 7 netmask issue? 023 Address Family Inconsistency In This Connection=2 Host=2/nexthop=0 This saved me a lot of debugging time.
