26sec using IPcomp
From: Marco Berizzi
Date: Sat Jun 25 2005 - 06:09:07 EST
Hello.
I have setup two Openswan 2.3.1 boxes with
linux 2.6.12 (Slackware 10.1).
I have established an ESP/IPcomp tunnel. Tunnel
is correctly established, but there is no packet
flow when these are bigger than 295 bytes.
(Same behaviour with ipsec-tools 0.5.2 When I
disable IPcomp, packet flow is fine.)
Is there any know problem with IPcomp on
Linux 2.6.12 ?
What should I do to debug this problem?
Any feed back are welcome.
