agreed (duh), so I ran some more tests:

Case 1.

-2.0.36 running netscape --[10Mps ether. eth0 MTU=1500]->
-2.2.1(MASQ router eth0 MTU=1500, ppp0 MTU=576)> --(ppp modemlink)->
-2.0.35(dial in ppp0 MTU=1500)
^^^^^^^^
Result: works fine

Case 2.

-2.0.36 running netscape --[10Mps ether. eth0 MTU=1500]->
-2.2.1(MASQ router eth0 MTU=1500, ppp0 MTU=576)> --(ppp modemlink)->
-2.0.35(dial in ppp0 MTU=576)
^^^^^^^
Results: -Netscape on 2.0.36 host DOES NOT WORK with this site
-Netscape on 2.2.1 router works
