BT Infinity Blocking VPN?


[link to this post]
 
About a month ago I noticed I could no longer get ANY data transmitted when connected to my UK Strong VPN connection on BT Infinity.

I tried the PPTP and L2TP and neither work.

However I can connect to the US VPN I have with them no problem.

What is going on? Is BT blocking VPN and if so why is the US VPN working but not the UK?

Strong VPN say that there is no problem at their end....

No problems using PPTP and IPSec VPNs on BT Infinity here - but I'm not using the Home Hub.

Try changing your DNS servers on the PC. Try lowering the MTU. These are the usual suspects.

Lower MTU on the PC first, don't touch the router.

Have not come across it ...

In line with others: what are the MTUs that you have set? Router and PC. Have you changed any firewall settings on the router and blocked any ports?

I'm on a Mac..

If anyone can take me through how to change the MTU and open the firewall on the HomeHub up/ change the DNS then I will try those.

If does seem like a strange problem.
