Changed ISP now can't get to websites / traceroute

What's your trace to www.freebsdforums.org from a Windows machine?
I don't see why there would be a problem for a particular IP range on
Zen, but not for others, being that all of Zen's ADSL customers connect
to the same PoP and use the same transit.
I wouldn't know how the Vigor 2600 works with regard to packet filtering
by default, but something tells me it's blocking something somewhere....
Do you still have your old router? Perhaps try it with that and see if
it makes any difference.

Shucks :-(=20
I know that *some* folks on Zen can get to the site, but I'm wondering
if its to do with the network range I've been assigned here. That's
certainly what Zen tech support have told me just now.

Yep.., When with PIPEX, I was using the SMC ADSL Barriccade which worked
for near on two years flawlessly. Now I've got this Draytek Vigor 2600
router that Zen recommended to me.
The thing is, its set up with its default, basic setting for simple
connectivity. That said, why would the Win2K & XP boxes work fine, but
not one single *nix box?

See above.
Thanks again..,
