This is off-topic. Better change your IPSec config instead the gatekeeper config. Take Linux native IPSec instead of FreesWAN. http://www.ipsec-howto.org, 1st example. You can use the backport for kernel 2.4 if you don want to switch to 2.6 greetings, Steffen -- Steffen Pfendtner <steffen@wh-netz.de> GPG Key fingerprint = DF91 11BB 498F 573B 8002 6E0B 3AE3 FF88 EADD B3BC ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
