Greetings & Salutations everyone...=20

A word of warning: While I'm not to terribly new to networking with NT =
or Linux I am very new (today makes day 1) to having to mess around with =
our Livingston firewall/router.

My objective: To block traffic coming in through the router on TCP port =
139.

My progress so far: I succeded in utterly sealing our network off from =
the internet... on all ports... heh heh. Had to reset the router =
(couldn't get back into it with PM Console). Fixed all that mess.

My question: What do I need to read / where can I look for info on doing =
this properly. I looked at the page on the Livingston website, and found =
what I *thought* was the info to do it. But my filter doesn't seem to =
work.

I was trying this: deny tcp src eq 139

It's probably horribly wrong, I know...

If the answer is RTFM then tell me _what_ FM to read! ;-)

Thanks

Brad
