[Openswan Users] openswan 2.6.18 klips with 2.6.24 - is nat-t patch necessary?

[Jorge Santos]

Hi

I just patched kernel 2.6.24.7-rt21.1.fc9.ccrma from planet ccrma srpm 
with klips 2.6.18. When using netkey, I am able to pass traffic to the 
to my enc domain, but when I use  klips, with no iptables rules and 
iptables -P INPUT DROP, iptables -P FORWARD DROP, iptables -P OUTPUT 
ACCEPT, I ping from the rw to the enc domain, but no reply comes back. 
Any suggestions

TIA
