I too had this problem with a static IP
and cable-modem setup. Civileme and Axalon
helped me through my gripes and confusion,
and yet it took me almost two weeks and talking
on the phone with not one, not two, not three,
but four tec-support individuals to track down
the problem and it was one who runs L-M 6.1 at
home that actually came up with the proper
diagnosis and solution.
First be patient with your tech people. Have your
MAC address handy. If you need to check , try
'ifconfig' (as root or su)
and its the 'HWaddr xx:xx:xx:xx:xx:xx'
(numbers and letters of course) on you gateway card.
Then ask them to check and see if they have "tacked"
a 'NetBios filter' on your assigned IP address
and to please remove it.
Don't rant about the inadequacies of M$ and the
"prowess" of Linux. That just gets them defensive.
If necessary, (if you dont already have it), ask
for a staic IP (usually about 10$ extra) at least
With my ISP.
Anyhow good-luck and I second or third Civileme's
motion to discover, design or invent a Linux method
to by-pass this kind of filtering agent.
