VPN Firewall Issues

I've set up PPTP on my OpenSuse box as I like to encrypt my traffic when using open WiFi hotspots.

Initially, all went well and I managed to make a VPN connection and surf the web. I had a small issue the other day which required me to reboot the box. Now, I can make a VPN connection, but no outbound traffic is getting out.

IPTables looks like this:

-A INPUT -p tcp -m tcp -i eth0 --dport 1723 -j ACCEPT
# PPTP Gre
-A INPUT -p gre -i eth0 -j ACCEPT
-A FORWARD -i eth0 -o ppp+ -j ACCEPT
-A FORWARD -i ppp+ -o eth0 -j ACCEPT

Thoughts?

I have had a similar problem with forwarding not working after a reboot due to /proc/sys/net/ipv4/ip_forward being set to 0 (needs to be 1 to enable forwarding).
Solved by putting echo 1 > /proc/sys/net/ipv4/ip_forward in my boot.local.

Thanks - tried that but still nothing doing..

I finally got around to revisiting this issue (sometime life just gets in the way). And I now have it working. It was definitely something odd with the firewall as tunnelling through SSH with PuTTY had also stopped working, but is all well now.

I ended up flushing all the rules to do with the VPN and setting them up fresh. I've now put the iptables.save in a safe place.
