Oh wow, it was just a case of hanging on the test call for a bit longer
- thank you so much!

I never saw that crucial bit of info in any of the guides I found and
it's perhaps a bit odd that the distro scripts added the 1st and 3rd
(as quoted below) rules to iptables but didn't add the last one.

Anyway, it does indeed seem that after a few seconds it switches over
to kernel forwarding, so thank you once again - you have successfully
managed to postpone my balding process ;)
