I'm using a Draytek 2930 (FW: 3.2.2) to protect my two servers at a hosting centre down in london.

I've configured it using the firewall filter, to forward DNS, Web, SMTP, POP3 etc etc

The error occurs after approximately 10 minutes of uptime, it will just stop filtering all together, no traffic can get in or out with the exception of RDP which mysteriously still works! However, if I make ANY change to the firewall filter (ie. enable or disable a blank rule) it will sping to life again.

In the syslog I'm getting:

"Ethernet destination address doesn't match ARP target adress"

But I can't see anything else that looks out of place.

Any help would be greatly appreciated!

High traffic?
