router firewall w/PC-cillin

by Disneyfan / July 31, 2005 11:40 PM PDT

I have a Linksys WRT54G router which includes a hardware firewall. I just purchased a copy of PC-cillin Internet Security 2005 which includes a Personal Firewall feature. Is there a way to configure the router's firewall so that the two will work together or am I in for problems?

I'd like to have the flexibility and ease of use of a software firewall but don't want to have to turn off my hardware firewall.

That router has IPSec (encryption) and NAT (Network Address Translation). Some consider NAT to be sort of a firewall, others do not. In any event, it does not act the same as a true firewall, either hardware or software.

There is no conflict between NAT and a software firewall; however, you should not use two software firewalls. You didn't say what OS you are using. If it is Windows XP, you should disable the built-in firewall and enable the PC-cillin firewall, which is better. Then there snould be no conflicts.

Ok, but now if I configure the PC-cillin firewall to allow some port range or URL to be accepted, will the router firewall know to let those through as well?
