You can't get all those things in a low cost solution. I end up rolling my own. My latest system is this http://www.supermicro.com/products/system/1U/5015/SYS-5015A-PHF.cfm

, with Endian http://endian.com/en/community/download/ and an additional dual port nic. With all the parts (HD,NIC) it's under $400. It's an atom board, so you could put whatever you wanted on it. I have a 50mbps net connection and it doesn't have any issues.Works well on GBit/s as well. I haven't measured the throughput yet, though. Should be ~500 MBit/s, assuming a single Atom core is about equivalent to a Pentium 3 at the same frequency.
An atom should easily be able to forward some high fraction of a gig between two pci-e 1x connected interfaces certainly in the soho context such a box can do ipsec at farily reasonable rates as well. Regarding equivalence to a PIII an atom is a scalar rather than super scalar device. it is slower clock for clock than a pIII but there are also multicore variants and of course they run faster at loewr poper consumption rates than the equivalent PIII derived embedded processor such as the intel a800
