There are quite a few services on this firewall it has 4 physical (sis(4)) interfaces of which all are used, 3 for Ethernet and one for PPPoE via mpd5, it uses a gif interface for IPv6 tunneling via IPv4, and a few IPsec tunnels are also configured and heavily used. arpwatch is beeing run on 2 of the ethernet interfaces so they are always in promiscuous mode, as a packet filter pf with altq is used.
