Hello,
I have a Vigor2820n and BE Pro as my ISP.

If I connect using the Draytek ADSL2+ annex M, I get an upload speed of around 1.1Mbps. However, if I use the BE Box (in Bridge mode), I get an upload speed of over 2Mbps. (I am close to the exchange).

However, the LAN-2-LAN VPNs don't function when using the BE Box as a bridge. (They function fine when using the Draytek ADSL connection).

Interesting, the speed tests are using speedtest.net. The Draytek actually reports a higher connection speed, but doesn't deliver in use.

I am assured by BE that the BE Box does not block any ports.

Does anyone have any ideas / suggestion?

How can I determine where the Draytek fails to connect?

Many thanks ... Andrew
