Hi there,
I was wondering if someone could help me. I'm looking to setup a VPN server on my RB450G for windows/osx.
I would like to segregate it from my existing configuration and network, but they should be able to get access to the internet once connected.

I'm not sure if its possible but I'd like to give each user a dynamic IP address on once they've connected.
Thank you.

You can firewall that traffic in the 'forward' chain just like you can firewall everything else.
