I found that pinging worked and I could connect to an SSH port but they 
SSH key exchange stalled so I guessed MTU and got lucky.

OK.

I later tried l2ping -s 1500 -a pda and it worked so I'm not sure what's 
going on.

OK.. I wonder where the problem is :(

I have done the same operation on the same hardware in Linux and it 
worked without MTU tweaks, however I haven't looked to see what MTU it 
used or anything.
