Router firewall secure enough?
 
I just got a Linksys WRT54gs wireless router that I had intended on using with my IPCop blue interface. But when I tried to set it up, I couldn't get them to talk to each other. So now I have shut down (temporarily, I hope:eek:) the IPCop and am running the router straight off the cable modem.

I prefer the IPCop firewall, but is the firmware firewall secure enough for home use? It's better than nothing adn I've got WPA2 encryption enabled, but I think that is a separate deal from the firewall.

So am I putting my poor network at risk?

I would say check your ports on your router , take a look at www.grc.com for a port scan

maybe get someone to nmap your ip address too perhaps - i have done this with a mates linux box setup in the past and I dont use a sware firewall only my router firmware firewall which you should have the option to update in its setup

also make sure you have your system security updates installed on a regular basis too.

I have had no probs in over 3 years with this setup btw!!

Yeah, they passed at GRC. Maybe I'll stick with this for a while and see how it goes. Should be easier on the ole electric bill not to have two comps running 24/7.

This site will perform a much better scan than grc.net. Basically they will do an nmap scan of your IP and you supply the command line arguments to tweek the scan. Read man nmap before you go there.

I think the trick to getting the blue interface set up on IPcop is to speak only in terms of MAC addresses, not IP's when it comes to your router.
