Hello,
I am trying to connect strongswan with openswan.
It works for 60 seconds, then it all dies until I restart ipsec, then it
works for another 60 seconds...
$ sudo ipsec status
Security Associations (1 up, 0 connecting):
hub[1]: ESTABLISHED 17 seconds ago, x[x]...y[y]
hub{1}: INSTALLED, TUNNEL, ESP SPIs: ca70896d_i 1d4e67fe_o
hub{1}: 192.168.45.0/24 === 10.193.160.0/23
Fine, connection is up and running!
After one minute this happens:
$ sudo ipsec status
Security Associations (2 up, 0 connecting):
hub[2]: ESTABLISHED 11 seconds ago, x[x]...y[y]
hub[1]: DELETING, x[x]...y[y]
hub{1}: INSTALLED, TUNNEL, ESP SPIs: ca70896d_i 1d4e67fe_o
hub{1}: 192.168.45.0/24 === 10.193.160.0/23
Log entry in auth.log
May 26 22:49:27 toto charon: 08[IKE] y is initiating a Main Mode IKE_SA
May 26 22:49:27 toto charon: 15[IKE] deleting IKE_SA hub[1] between
x[x]...y[y]
Then all trafic is dead:
$ sudo ipsec status
Security Associations (1 up, 0 connecting):
hub[2]: ESTABLISHED 2 minutes ago, x[x]...y[y]
Here are the logs from the openswan server:
