I've got a little 4 port linksys wireless that I use here at the house... can't divulge the work setup... but yeah, the nat capabilities are great. all I have to do is deny any port I don't want coming in, and I am feeling good. But... as we say in the IT Sec world, "Firewalls and routers are just speedbumps in the internet super highway." Don't rely solely on them.
AMD Duron 1ghz running a NAT kernel and IPtables to manage the DSL connection, and be the firewall. Plugged into a ~5 port 10/100 switch, and then one port on said switch providing upling to a little 10 mbit hub that I plan on replacing soon (tomorrow has come to mind, I'm getting sick and tired of the thing)
Been using routers for years, Linksys!!!! Have always use Linksys routers and Linksys cards in the systems I build. I've only had one problem with their routers and they replaced it very fast, was quite impressed, and the built in firewall is a bonus.
All my networks are hardwired, I don't trust wireless. From what I have heard, no one has the security on the wireless like you can have when hardwired.
I have a similar setup to Danann. 4 port Linksys wireless router. The difference is I don't have a firewall running on the router. I have personal firewalls running on the PCs. So far that's worked. I have ethernet address filtering running and all transmissions are encrypted. So, although it's not foolproof, it would at least slow someone down from getting in. DHCP and NAT are handy.
Normal is a relative term. For some reason it is not a term my relatives use to describe me.
noone critisized my work outside the home either =) I just had issues with getting the hardware working like it should. Got it going eventually, but it simply didn't want to work right. Don't remember exactly what OS it was, but at the time the shop was running 98, and 2000.
