Hi
Ok, here's the scenario.
You have an Ubuntu Server on a dedicate root server on the Internet somewhere with a public IP address, at the backend home office you have a small LAN connected to the Internet using a DrayTek Vigor Router.
The ISP __ONLY__ provides dynamic IPs and switching ISP for static IPs isn't possible.
You want to use iptables on the Ubuntu server to lock things down but open up SSH to the home network, but how would you do this with a dynamic IP Address?
Options? Discuss??
