Grrrr!

This is a known issue with the PAT/NAT on all of the most recent Draytek firmware releases, so why hasnt it been fixed!

I have found as you all have that a reboot sorts out the issue as it seems to clear the NAT sessions table and it works ok for a while

I have a 2930 and am having the same issues.. does anyone know of a new beta firmware for this model?

Thanks

Same problem here, both on 2830 routers and 2710n running 3.3.6.1 firmware

It's not very good as its a pretty common requirement. I've stopped using the 2830 until it's sorted out and the next revision of software for the 2830 seems to be taking an inordinately long time to appear.

I maintain a network which has about 10 Yealink handsets connecting through a 2820.
If I leave the default filters enabled in the firewall section of the router config my phones all gradually de-register and will not re-register.
Turning the default call and data filters off completely solves this problem.
Also I have a load balance policy setup to send all traffic to the SIP server over my WAN1 connection and it just ignores it sometimes even though most of the connection honour it.....random!

At the risk of quoting myself:

Mine's been running for over a week on this firmware now with no issues whatsoever and no reboots required.

I haven't had a deregister in over a month now.

The 3.3.7 firmware is published at www.draytek.com which resolves these registration issues :)
