My dad and I had fits with SBC trying to get his 5 "static" IPs to work. They sell you a lovely NETOPIA router/modem that will do it but only if you either use it as ONLY a modem or you pay netopia for an additional unmentioned firmare patch to the tune of the hundred that the thing cost in the first place. Sooooo NO firewall but what your system has exists at all if you want to have more than one IP. Lucky we have a set of linksys routers to drop in in series thanks to my dad being a tech packrat and saving the old ones as he upgraded (only one FULLY works but the others can be beaten into doing the limited things they need to IE the local net doesnt need DHCP and static at the same time so the cruddy box will do nicely there.. etc)

Their tech support people in india? were nice enough but no help, the guys in Dallas were more helpful but it still took two people and several hours to get enough information out of them (by walking through their scripts) to set it up in a completely different way (as none of theirs worked right)
