DrayTek 3910 Connection Error

We are trying to connect to our 3910 - draytek router the connection was reset.

The router normally responds fine.

Today, and for a few days now, we see this:



Do we have to restart it?

Telnet is refusing connection also so it must be some kind of routing issue?

Or maybe DDoS response?

This appears to be the new firmware. Although it has actually fixed the issue with the NATting of outgoing traffic, it has now brought another problem - you have to reboot the router every time you want to connect to it.

God I wish we could go back to the 3900!!!!

This thing is a liability!!!!
