Can confirm that the 2860 with both the initial release and latest beta release also suffer from this DNS bug. Wish they would fix it as my FON adaptor refuses to work.

Ive replicate it as well

i m down to Greece for few good weeks and was using only wan 1 with adsl (wan 2 is disable) using here the 2830n at the moment
Wan 1 was fine but once enable ipv6 with 3.6.4 firmware i seen port blocks with ipv4 & ipv6

normal test
Direct TCP access to remote POP3 servers (port 110) is blocked
Direct TCP access to remote POP/SSL servers (port 995) is blocked

ipv6
Direct TCP access to remote POP3 servers (port 110) is blocked
Direct TCP access to remote POP/SSL servers (port 995) is blocked

The adsl thinkbroadband monitor is fine but when i enable ipv6 will give long spikes with wan 1 as well same as my previous post in this thread
For sure something mismatching there

I logged with Draytek and have a new firmware to test with now.

Ill let you know the out come

@sicon, please test looking up the root name servers:

nslookup -type=NS root-servers.net 199.7.91.13

Server: 199.7.91.13
Address: 199.7.91.13#53

root-servers.net nameserver = b.root-servers.net.
root-servers.net nameserver = h.root-servers.net.
root-servers.net nameserver = m.root-servers.net.
root-servers.net nameserver = l.root-servers.net.
root-servers.net nameserver = g.root-servers.net.
root-servers.net nameserver = k.root-servers.net.
root-servers.net nameserver = e.root-servers.net.
root-servers.net nameserver = j.root-servers.net.
root-servers.net nameserver = c.root-servers.net.
root-servers.net nameserver = a.root-servers.net.
root-servers.net nameserver = f.root-servers.net.
root-servers.net nameserver = i.root-servers.net.
root-servers.net nameserver = d.root-servers.net.

Well txt now works with the firmware I've been sent but the root names servers timed out
