Hi all, I have an extremely weird problem with IPsec tunnels in DL: I have upgraded two firewalls that are linked by IPsec tunnels from gibraltar to DL-1.2.9 (Gibraltar had Freeswan 2.0.4, DL has Openswan 2.4.4) When I try to establish a TCP connection to any windows server (2k, 2k3), the server restarts immediately (bluescreen, complaining about TCPIP.SYS error, and reboots). Connections that go through the DL firewall but not the ipsec tunnel to the same ports on the same servers (either plainly routed throuh the firewall, or with DNAT) are fine. Pinging the servers through the ipsec tunnels is fine also. When I revert one end of the tunnel back to Gibraltar/FreeSWan-2.0.4, the servers on _that end_ of the tunnel are safe. The crashing can be triggered either by normal windows clients trying to connect to the server, or by a linux client that does 'telnet x.y.z.t 25' to the server. I am really desperate with this one, so if anybody has any hints, I'd be very grateful. Thanks Frank |
