I've just been evaluating a pair and they're rubbish. Keep rebooting and crash at the slightest hint of a sipvicious attack.I read your posting elsewhere about this. Oddly enough, I have both a Draytek 2820 and a Zyxel P660R. The Draytek was diabolically bad and kept dropping the ADSL session (which it then re-establishes very slowly), whereas the Zyxel has been very solid and when the connection does drop it brings it back up very quickly. It's entirely possible that the results you get depend on line quality. Ours is fairly poor and I think the Draytek just can't cope.
Indeed - however my line quality is OK - well, it's OK enough to get the full 8Mb in/832Kb out, but both routers have no issues maintaining line sync.
I can crash the Zyxel in about 5 seconds flat if I aim a sipvicious attack at a non-natted host inside it. That's not acceptable to me. My 6 year old Draytek 2600 just keeps on going. I will try it with the sip alg off though - although in a non-nat situation, and with incoming registration traffic, the sip alg should not be being used.
If it could handle that, it might be OK for a 50 quid router - the traffic shaping seems OK. I'm actually going to deploy one on Friday with a customer who just has a few phones on the inside (using a virtual PBX) rather than have a PBX on-site, so no chance of a SV attack on them.
