i had installed freeswan-userland utilities and freeswan-modules in my redhat linux 9 proxy server but when i start ipsec service it gives below error.

ipsec_setup: Starting FreeS/WAN IPsec 2.06...
ipsec_setup: insmod: ipsec: no module by that name found
ipsec_setup: modprobe: Can't locate module af_key
ipsec_setup: modprobe: Can't locate module ipsec
ipsec_setup: kernel appears to lack KLIPS

please tell me how to fix this error and also suggest me the configuration files for server and client here i am giving the ip address and kernel details:

eth0: 192.168.1.2
eth1: 59.144.124.54
Kernel: 2.4.20-8


and also i have a question i mind if it is configured properly how to i connect from client end?
