I have just checked and on my Fido connection neither of those ports are blocked, port 1434 however is blocked. I am using my gateway in bridge mode, I don't know if that is relevant or not.
I disagree, I have my own VPN server and I've just run a test on my 60/10 plan and I'm seeing 68/10, a little slower than the 74/11 I normally see without the VPN, but not much. I am in the GTA and my VPN server is in Texas.
