[NTLUG:Discuss] Lock up - from port scanning?

In the past few days I've found my gateway locked up. I have a cable
Internet connection through AT&T.
The gateway runs in command line mode only and does not respond to any
key I press. Even if I try another virtual terminal (Alt+Fx). I can
only see the blank screen (saver). In addition, the connection with the
Internet is disconnected. The only thing I can do is hard boot it.
When it comes back up everything seems to work fine.
A possible relationship could be this entry I've noticed in my logs:
Feb 1 23:25:26 c55493-a kernel: IP fw-in deny eth0 TCP
24.0.94.130:40069 w.x.y.z:80 L=40 S=0x00 I=7798 F=0x0000 T=245
I did an nslookup on the ip address above and it returned this:
Server: proxy1.grlnd1.tx.home.com
Address: 24.4.48.33
Name: ops-scan.home.net
Address: 24.0.94.130
I've contacted AT&T @home but not received a reply yet.
Could it be that if someone was scanning my ports, my machine could lock
up? Or is this totally unrelated. Should I look for other possible
causes? Do you have any suggestions?
Thanks,
kelly
