Internet access, linux not ok, windows ok, *bsd ok

So what seemed to be a problem? Recently, within our network segment, guarded by pf firewall, somehow linux(redhat,fedora,*buntu) found difficulty in accessing the internet. Either the page is half loaded, or did not come out at all. It is not the browser; same result using wget. Obviously it is not the network; since XP and *BSD can go out. So, I suspect the pf is the mole. But since the pf owner is not around, and IT department could not be much of a help unless the problem affecting their segment, nothing much can be done. Plus I'm half system admin I used to be, too lazy to trace out the root cause now. Btw, here's the definition of problem based on ITIL concept(taken from wikipedia):

A problem is a condition often identified as a result of multiple Incidents that exhibit common symptoms. Problems can also be identified from a single significant Incident, indicative of a single error, for which the cause is unknown, but for which the impact is significant.
A known error is a condition identified by successful diagnosis of the root cause of a problem, and the subsequent development of a Work-around.

I know this is an ancient post, but for "Windows OK, Linux Not OK" or similar searches it ranks pretty highly, so if ever solved this, the world may be a slightly better place for getting some info here.

I have a similar problem. Multiple Windows machines on the network OK. Multiple Linux machines on the same network have very problematic connections. Not dead, but incredibly slow,, lots of time-outs, etc.
