Subject: Re: Problems with a forward rule

So, when you do a ping from your host 172.24.50.3 to 1.1.1.x you will 
probably see the counter increase for your rule (with restricted 
destination).
Do "iptables -vnL FORWARD" to check.

That rule is not the problem.

What traffic are you sending that times out?
source ip, source port, destination ip, dest port, protocol?

Your forward and postrouting rules look fine and should work

Regards,
Tom
