Almost every time I connect to the net, I receive something from port 137 -
and it ain't from my HAN, SMB, from various IP's out there. Strange. Its all
logged in da firewall.
Why on earth would your ISP be SENDING Netbios (and protocol 89 (137
decimal) is Netbios, not routing table updates) packets to you, I wonder ?
If these packets are incoming from the ISP then filtering won't help,
because they've been received by the ISDN transport layer (at which stage
the timeout gets restarted) before they get near your filter. I think it's
time to call your ISP and get to talk to somebody clueful (probably NOT the
first person who answers the phone) and tell them to stop the hell sending
you those packets.
Mind you, it is very curious that everything was working fine before you had
the reboot. One other thing to check - if you disconnect your gateway box
from your internal LAN, and fire up the connection, does this still happen ?
I'm wondering if perhaps there's something one of your internal 'doze boxes
is doing which is causing these.
