We've lots of experience with routers, firewalls, etc. - but always when they are connected on the backside of a WAN device (cable modem, DSL modem, bridge, etc). We're installing a new rural office that will have a traditional T1 circuit. Ultimately this will be a typical 802.11 wireless setup with some wired LAN ports. We're drawing a blank. Should we buy a self-contained router/firewall with the T1 connection built in? Which one? Or should we buy a T1 connection gizmo that gets us converted to a WAN port and plug it into a simple wireless firewall/router? Please aim us, oh wise ones.
