Please help with my bridge/router

[Serge Matovic <matovics@yahoo.com>]

Hi to all. I'm a bit hesitant to bug you with this
basic problem of mine, and I just hope that I'm not
wasting your time.
OK, here is the situation. I have a Linux machine with
4 NICs. I have configured 3 of these NICs into a
bridge (br0), and the 4th NIC is connected to an ADSL
modem (ppp0), which, in turn, is connected to
Internet. This NIC is getting a DHCP address from my
ISP. I'm using the iptable script from dranch's
IP-MASQ-HOWTO. (and I tried many other ones, as well).

Now here is the problem: When I try to go Internet
from my Client computer (connected to one of the 3
NICs of this bridge/router) some sites (like
Google.ca) connect and work perfectly, ***BUT*** some
sites (like globaltv.com) do not load at all. But I
know that they work fine when I connect to them
without going thru my bridge/router.

Does anyone have a thought on why some sites work and
some don't?

Many thanks, and best regards,
serge.
