[Openswan Users] Tunnel up, ping Ok, but no communication with others protocols

[Gildas Delon]

I have read some posts who have the same problem but no solution works.

My configuration :
- 2 gateways Fedora Core 3
- kernel  2.6.9-5.0.3.EL.notting.ipsec
- Openswan 2.3.1.2
- ipsec-tools-0.5-2.fc3

My tunnel is up and I can ping any hosts on the other side, but not with 
others protocols (ssh, http, pop....)

It's very strange, my firewall is ok, no rules block VPN traffic. When 
I'm loading a html page I can see in apache logs the packets arrived, 
but is very slow and I have a Time Out message in the most of case.

This is not a MTU problem I think because I can ping with packet size 
very large.

Load a on a local machine i

Someone have an idea ?
