A quick question. I'm interested in changing the firmware of this old Linksys WRT54GS v1.1 that's sitting in front of me. However my time to muck around and hack things is limited, so I'm looking for a KISS solution: 1) I would very much like to be able to have this box work with my SPA3000 SIP box to enable me to maintain/combine services from multiple VOIP providers. The sipura box can already already deal with multiple OUTGOING gateways, but what I'm interested in is having different INCOMING numbers, from different providers, all routing and working with the sipura box (that can only normally deal with one provider). Not sure what the technical term for this is, but it would be very useful. 2) Is there anywhere that compares/contrasts the performance of the various firmwares as firewalls, or is it all the same? From the comparison of other features I read the DD-WRT seems the most feature rich, but the key for me is something that's not wide open to attack. 3) With a nice Linux box running 24/7 its just crying out for being used for more than just routing/firewall. Are there any other particularly juicy tasks that these boxes can be made to perform?
