[Openswan Users] Link established no data going through

Hmm, ipsec verify looks ok.
I don't see any problems in your iptables firewall rules, they look ok.

How are you doing your ping tests, from a computer in the local lan to
A computer in the remote lan? Or openswan server to openswan server?
If server to server your subnets are not setup for that, use lan pc to lan pc.

Do you know where fc puts log files, most Linuxes put in /var/log.
Openswan logs with process name pluto.
Generally grep 'pluto' /var/log/* should find your logs.
