Sure you can do that with dhcp. go to www.no-ip.com and register a
subdomain of no-ip.com, download the updater client (works for
win/linux/mac) load it up on the firewall and setup port forwarding on the
firewall to forward in your ftp/http/smtp/pop/telnet/ssh whatever
connections. I am doing exactly that - dsl line, linux firewall, three
computers behind the firewall one of which is http/ftp/smtp/pop server.
