RE: local proxy udp 53

["ops-security" <ops-security () edreams com>]

Hi Julian

DNS is a critical service and is very important the response time. A proxy that rewrites request to another 
request can worse the service response time.......
Anyway you can view a very great tool that can be usefulness for this and another works....as create a tunnel
between proxy and external provider by https and you do request to proxy in HTTP internally....for example...

http://www.delegate.org/delegate/
ftp://www.delegate.org/pub/DeleGate/Manual.htm#DNSCONF

If you want to do a test over proxy it seems good, but if you need a proxy to offers a service, I think that is better 
configure a dns cache.

I hope help you!

Asunto: local proxy udp 53


Hi Group,

I wonder if there is a proxy which is configurable that it rewrites every request to special DNS request and is sending 
and receiving on port 53 UPD/TCP. Additionally there should be a server listening on port 53 UDP answering all requests 
the client is sending.

Background to this question is, I'm currently testing a wireless network which allows traffic on port 53 to every 
server. So why not tunnelling s this way! I don't want a tool where I need my own DNS server with authority of a domain 
and so! 

Cheers -j
