I have VPN net-to-net tunel with one peer nated (two Astaro boxes 5.102). I use RSA keys with FQDN as ID. The VPN is established without any problems, but if the IKE SA expires (7200sec) the VPN is broken. Following messages are recorded every 40 sec in IPSec VPN log:
packet from 193.165.232.148:4500: received Vendor ID payload [draft-ietf-ipsec-nat-t-ike-03]
packet from 193.165.232.148:4500: ignoring Vendor ID payload [draft-ietf-ipsec-nat-t-ike-02]
packet from 193.165.232.148:4500: ignoring Vendor ID payload [draft-ietf-ipsec-nat-t-ike-00]
packet from 193.165.232.148:4500: initial Main Mode message received on 10.0.0.101:4500 but no connection has been authorized with policy=RSASIG
Similar problem was discussed on Open/Swan forum and resolved by a patch (http://lists.virus.org/users-openswan-0410/msg00281.html)
Any sugestions?
Thanks
Karel
