I need to get a new router for the following reasons: 1. I only have 3 static public IP's from my internet service provider 2. I have 6 computers, soon 7. 3. I suppose a firewall would be nice 4. DHCP is easy So, I was thinking about a unit like this http://www.dlink.com/products/broadband/di604/pdfs/DI604_DS.pdf It says it only supports 4 computers, however. I was thinking that it only supported 4 computers because of 4 physical rj-45 jacks. But I looked at their more expensive, 90 dollar router, and it has 7 physical jacks, but says it can support 253 connections. I need something that can be expanded in the future. If that little router can't support more than 4 computers, its worthless to me. Also, 2 of the machines (my brother's) will still be getting their static ips like normally. I would just interface my network with theirs so that I could get internet access and browse their files. Another option I suppose would be to configure a machine as a firewall/router/dhcp/domain server using linux. That would be ok, I suppose, but would I get too much of a performance hit? I also don't want to spend weeks setting the thing up. Suggestions?
