What kind of connection do you connect to your ISP with? ADSL, DSL, PPOE or PPPdial-up?

I thought that you couldn't get to the internet when the MTU was set to 1500? Of-course sites are
going to load slow when your mtu is set to 200. Assuming that you can't get out to the internet
when the MTU is set to 1500 you should try 1492 next. An MTU of 1492 is usually needed if you have
a PPPOE connection to the ISP.

Without Shorewall installed are you able to get out to the internet without any problems?

Meaning if you were to take One machine and and only one machine and hook up to the internet
without shorewall installed on that machine would you have the same problems? If you were to take
that same PC and only that one PC and install Shorewall do you still have the same problems?

Your shorewall logs will show us possibly whats happening. If I were in your shoes I would install
tcp dump and or ethereal to see whats happening for sure though. This will be your best friend in
this situation and will help isolate the problem in a more timely manner.
