Simple Firewall UI - feature request, insert admin's ip rule automatically.

[vsilent]

It would be great to have a firewall section where we can allow or block IP's and ports.
It makes sense to detect admin's IP and automatically insert a rule to iptables on the first login

1. Admin login.
2. Admin confirms IP obtained by app in a window popup on first successful login.
3. App modifies iptables with new rule for example allow SSH only from admin's ip and drop all other ips.
4. Admin can read iptables rules in web UI but can not modify any.
