For those of you who may not remember, my problem was not being able to reach
certain URLs from Win98 machines connected to my ADSL line via my LINUX box.
In the end, it turned out not to be a LINUX problem after all. I finally got
around to using ethereal to try to see if the MTU was properly s

OK - I tried Guy's advice and came up with 1372 + 28 = 1400 which is exactly
what was already suggested and didn't solve my problem. I had already set the
Win98 MTU to 1400 in the registry according to the instructions in the
ADSL-Bezeq HOWTO. I'm obviously doing something wrong. But I still hav

Yes. It looks OK. This should adjust the client's MTU to the size
determined by PathMTU Discovery initiated from the router.
Try the following to eliminate a problem with MTU:
>From your Win98 box run:
ping -f -l java.sun.com
where is TCP's payload size.
Start from 1472 and go do

If the site blocks ICM's source-quench, PathMTUDiscovery algorithm fails
and the client can not determine the appropriate MTU for the
destination.
Blocking all ICMP traffic is not always a good idea.

That's exactly the symptoms.

Do you have --clamp-mss-to-pmtu in your iptables script ?
Something like:
$IPTABLES -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS \
--clamp-mss-to-pmtu
