clear OS Block all outgoing traffic unless out to VPN

In clear OS I can block all outgoing traffic. Using Block Mode "Block all
outgoing traffic".
This is exactly what I want. However with this mode on I cannot connect to
SQL Server via a VPN. I can ping the server by host name, URL, and IP and
it responds. But I cannot connect using SSMS until I turned block mode
off.
Any thoughts on allowing the SQL server to talk back to VPN clients.
