You don't say which is which, so I'll assume 192.168.1.78 is behind 18.104.22.168 and 10.0.2.15 is behind 22.214.171.124. My ifconfig: eth0 Link encap:Ethernet HWaddr 00:0C:29:1B:F5:1C inet addr:192.168.1.78 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe1b:f51c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:829 errors:0 dropped:0 overruns:0 frame:0 TX packets:704 errors:0 dropped:0 not that there's some kind of port punchthrough going on, but that each has an interface which possesses a public, routable ip address. You cannot use 192.168.0.0 / 16 on one side, and 192.168.20.0 / 24 on the other.

Please be careful what you include and how your format your posts. But i think you sort of messed up on the subnetting. can you confirm that the two openswan endpoints posses public ip addresses on their external interfaces? i had a secret file i did not see.

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.
