i want to whitelist a computer, to allow all outbound access.
We'd be happy to help, but we'll need to know more about how the traffic is being blocked in order to help.
-Do you have any logs from the firewall that show the Block/Deny? This can help identify what feature may need settings changed.
-Can you elaborate on what you mean by issues with VPN? Are you able to connect and it's slow, or are there other issues?
