DNS port forward
Hello all
I seem to be having trouble forwarding DNS to my server.
I have setup port forwarding 53 TCP/UDP to my server IP, but when I test it I only get a responce from TCP. To test I se...

I don't have an account with BuddyNS, so I assume that I can't use
their "a test service within there consol", and "UDP queries ERROR"
doesn't tell me much, either. I'm far from an authority, but my dim
impression was that UDP was used for DNS much more than TCP, so that if
UDP port forwarding was bad, hardly anything would work. (And, as I
said, "I haven't noticed any problems" around here, but I don't know how
to reproduce your test(s).)

No, it does say. As I said, I was looking for a way to compare the
behavior of your server with that of mine from an outside-world
location. And, as I complained before, "I have also used several other
internet based DNS test services" was less than helpful.

You think that the _hardware_ is the problem? That wouldn't be my
first guess.

Thanks for the lecture. I have a domain and a DNS server under my
control.

Google does not tell me how you tested your DNS server, which, as you
may recall, is what I asked. My goal was not to waste my time trying to
guess how to replicate your tests and/or results. It still is.
Read my second post, it does tell you what I did to test. Although it doesn't say I did the nc command tests from another server on my LAN.
I changed my firmware to tomotoUSB in an attempt to resolve this, but that didn't work for me, so I switched back to the factory firmware. I'm thinking of ditching the router as this is the obvious problem and I'm simply not skilled enough to resolve the problem myself.

I have mananged to resolve the issue.
I went back to a smoothwall firewall and simply attached my router to it as an AP. Now the router does nothing but connect wireless clients and the smoothwall does all the internet management.
Port 53 UDP has security issues, so I'm assuming netgear have setup security so hard for my router that it blocks it completely. As I understand it, port 53 TCP is used prodominently for basic DNS requests, where port 53 UDP for the most part is used for delegation/transfer etc requests.
