There's definitely a bug in 3.3.4 DHCP. I've got a problem with it not giving out bound IP addresses after a while.

same here ..since 3.3.4 not giving out IP addresses to devices identified in the the 'bound to mac' list.

Also, 2820 appears to be totally screwed this evening ...
got 3 green LEDs on LHS alght for about 10sceonds, and NO lan link LEDS on the RJ45's
then..
all link LEDS flash on briefly..
then
all nine LEDs on the LHS flash on then off ( twice ?) together
then get ACT and QoS LEDs on briefly...
then the cylce repeats

I cant log into the router to see whats going on .... tried factory reset.. no joy

Support have suggested taking out machines from the bind-to-mac list. Tried this and they immediately got a DHCP address.

Roll on 3.3.5

Seems to be the only workaround (other than 3.3.3!)

I have noticed the "NAT Active Sessions Table" still had dozens of entries for a computer that was disconnected from the VPN 2 hours earlier - so I think there are a few bugs that need sorting out...

Still on 3.3.4 and have checked the the NAS box sys log, it is getting its DHCP renewed with no problems every 36h! It is still in the bind IP to MAC table in the 2820 at 192.168.1.10 and the start IP address is 192.168.1.10.

Seems to be a problem with devices that come and go, rather than just regular renewals. I've got problems with laptops (some are wired only) and (cough) iPhones that are coming and going from offices.
