We have a configuration like this: 5 static ip's coming in on each of two broadband lines, 1 primary, 1 backup, serving 5 different internal sub-nets. This is currently managed by a loose collection of SOHO routers and switches that has accumulated over time. All of the routers have port mapping for a number of ports.
We're wondering if there's a single (not too expensive) device out there that could do all of this in one (route static ip's to virtual sub-nets with port mappings, etc.). All of the ones we've seen are pretty expensive. Any suggestions?
