Have you got DoS defense turned on under the Firewall section? UDP flood defense is the only thing that I can think of that would cause that to be flakey.

all working previously and upgraded from 3.3.3 (there were issues for me on the intermediate releases), Since the move to 3.3.7 i now seem to be getting intermittant DNS issues with this one.toibs wrote:
DNS's are the same as they have ever been (isp's own) and have never experienced issues. They confirm no isues over the last few days, however now, whilst i am still seeing ppp session up and happy, DNS's seem to disappear (Well they are still there, however things intermittantly fail due to "no dns"...
This is on both a wireless and wired connection.
This is on an .all install with no old backup (re-built from scratch).

I use PRTG Network Monitor on my home network.
Upgrading from 3.3.5.2 to 3.3.7 (*.rst, but uploading an old config file rather than a manual rebuild) breaks the SNMP logging that PRTG relies on.
The SNMP settings in the 2820n web GUI (system maintenance -> management tab) were unchanged; no extra settings or any changes apparent between the firmware upgrades.
Anyone else had a similar issue? PRTG works (i.e. logs throughput) again instantly if I pull back to 3.3.5.2

I've tried a package called VitalSuite (VitalNET) used in ISP's, SP, MSP etc against the 2820n on 3.3.7 - worked on 3.3.5.2 but on 3.3.7 I have normalization issues trying to discover it. I've spent zero time investigating it as yet but the initial prognosis suggests the SNMP fucntions on 3.3.7 are broken

I had DNS issues similar to this, once every few days. Draytek support recommended "Increase number to 500 or more for Firewall/DoS defense Setup/Enable UDP flood defense(Threshold)". I did that, and the problem has not recurred in a couple of weeks of usage.

I have other issues with mine strangely - ADSL keeps dropping out once or twice a day. confirmed onto router since have replaced with a hacked homehub2 and all has been stable. Will try another install tonight...
Re my previous comment, i thought i;d done a full .rst as opposed to an .all install, since i had to re-install all settings from scratch. Will try it all again tonight from scratch again anyhow just to check...
