Hi all,
Thanks Karl for your previous reply but I was not clear in my previous
posts.
I am running a windows service that is monitoring the requests made on DNS
(port 53) when the request comes in. (service running on DNS server...)
Suppose a Web browser from a local machine (source is port: abcd IP:
m.n.o.p)
trying to connect to someplace (maybe google) whose ip: (f.g.h.i) and the
request is going through port "53" at your local DNS server (w.x.y.z)
can the DNS Server eventhough it can find ip: (f.g.h.i) in its table send a
response back to the local machine on (source port: "abcd" IP:
m.n.o.p)
saying "no--- you are always redirected to a.b.c.d which is an internal
(LAN)
machine"
So the machines involved here are:
DNS server : port 53, ip (w.x.y.z)
Requesting machine: port abcd, ip (m.n.o.p)
Redirected machine: port 80, ip (a.b.c.d)
can this be done using the windows service or does it require someother
process?
Hope I am making sense this time.
Thanks,
Stephen.
