All,

I am playing with different ways to knock out some frequently reported 
problems. This particular build lowers the MTU of the private adapter 
which avoids PMTU and MSS negotiation issues in my testing. If you have 
a gateway setup that was modified to use a lower MTU or uses a firewall 
to force a lower TCP MSS, *please* help test this build. You will first 
need to revert your gateway setting to its normal parameter so we don't 
get false positive feedback. After that, just connect as usual and let 
me know how if everything works as expected.

If this change proves to be beneficial, I will introduce a mechanism for 
tuning the virtual adapter MTU setting. This test build hard codes it to 
1380 bytes.

Thanks in advance,

-Matthew
