I'm using NAT on my 678. The default NAT settings seem to drop
incoming TCP connection packets, so I haven't even bothered to use
filtering. I assume UDP is dropped as well, based on my (Linux)
firewall logs. I've had to explicitly map some ports on the router to
ports on my Linux box so I could use services like ssh.

When I was using dialup, I probably had 30 suspicious port access
attempts logged per month on my Linux firewall. With the 678, using
the same Linux firewall rules, I don't think I've seen a single one.
