apt-get update error - Behind ISA server

[issekun]

hey guys,

i've been trying to apt-get update my system for quite some time, been following exactly the instructions on the site, http://www.psychocats.net/linux/sources.php.

i've config the network interface, can ping to other windoz machines on the network, i can browser the internet too, but cant apt-get update....... why? my internet connection is avalable through an ISA server - meaning i sit behind the ISA, is it because of that? if so how come i can surf the sites...but cant apt-get..?, i hooked the machine to a direct line and apt-get works perfectly... but not ont the network...

so if someone has an insight to this, pleas help me out [-o<

thanks..
