home-network

I'm trying to secure my home network but don't really need the complexity of a VPN so I'm trying to figure out other options.

I'd like to allow my iPhone remote access to my home servers but I can't depend on the IP address because it changes quite often (due to the 3G network, etc).

Can I filter incoming connections on my router (pfsense) by MAC address or does NAT change the source as it's passing through the different routers on the internet?

As I've mentioned in my other questions, I'm in the process of setting up a new Cisco 881 as my WAN router and NAT firewall.
