[Openswan Users] RV: IPSec tunnels OK, but don't work VPN

I has a MTU problem in White Box and I fix it with:
	# ifconfig eth0 mtu 1492

Now, I think, the problem in Fedora Core 5 is other because packets are not
tunneled by IPSec. As I said only ICMP packets are tunneled by IPSec. TCP
packets are not tunneled.

It's an MTU issue. Check the mailinglist for posted work arounds for it
including TCP MSS clamping.
