I'm having trouble setting up a VPN on my VPS that's running Ubuntu 11.04. I'm been following this guide

I'm able to start the VPN, but the command it tell's me to do after I start the VPN doesn't work for me. I've tried it about 5 different way's and i'll show you what i get now.

:~# iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables: No chain/target/match by that name.

:~# iptables -A FORWARD state --state RELATED,ESTABLISHED -j ACCEPT
Bad argument `state'
Try `iptables -h' or 'iptables --help' for more information.

I just can't get that to work and the VPN doesn't seem to be workign with out it.

Can someone help me fix this?

Your FORWARD chain is missing, you can create it with:

sudo iptables -N FORWARD

Consider using iptables-save and iptables-restore (or iptables-apply for remote machines) for saving/applying rules.

If you still have issues, contact your VPS provider for more help.
