what's your IP...I'll scan your router for adequate firewall protection.
If you want to do it yourself get a port scanner and run it against your IP address from outside your network (i.e. everything behind your linksys).
I like GFI's LanGuard plus. Comprehensive and nice report type output.
A firewall is only one tool to use in protecting your network. Make sure that the nodes behind it are also not running any services that don't need to be running, and that you have mitigated vulnerabilities for the services which are. Also make sure you don't have vulnerabilities to the firewall itself. Those SOHO dealios from linksys or netgear have default passwords (did you change them?), and remote administration (did you turn it off?) capabilities.
