[Devil-Linux-discuss] IPSec Problem, extremely weird.

[Frank W. <Fra...@ct...>]

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
