Hi - welcome to the club! I had EXACTLY the same problem. Drove me nuts
for about a week. Then, after LOTS of tcpdumps and a few hours with Comer
(as in "The TCP Gospel according to") I figured out what was going on.
When the BRILLIANT "engineers" at Microsquish did the TCP "upgrades" for
Win98, they added a "feature" that allowed one to set the MTU for DialUp
connections. All well and good - but, the BROKE the MTU/fragmentation
handling for all the rest of the TCP stack. So, when you MASQ, and your
MASQ box returns an ICMP_FRAG_NEEDED, the stupid Win98 TCP stack just passes
that message "up the stack".
The way I fixed it was to set PMTUBlackHoleDetect AND MaxMTU in the Win98
Registry. There's information on what keys to set where in the MS Knowledge
Base (not quoted here for bandwidth and copyright reasons). The Article
number is Q158474.
Have fun!
