Whoever said “size matters” is correct in at least one area, MTU packet size. My VPN connection to one of my client’s server was behaving erratically and I finally got to the bottom of the issue. The MTU packet size was too big! (don’t hear that every day).
I’m going to keep this short (pun intended) so I can get back to work and make up for last time. I had to run the following command from the command prompt:
netsh interface ipv4 set subinterface "Local Area Connection* 14" mtu=1200 store=persistent
After that everything worked fine.
