I have A record setup for adam.mydomain.co.uk which resolves to an ip address.
Is it possible to forward adam.mydomain.co.uk to the same ip address with a port on the end?
Ive gone through various options on my web server (vidahost), but doesn't seem to allow a port to be entered.

Not at a DNS level - you can setup a proxy on the server though.
Assuming you're using Apache:

As Ed said, if it's a webserver you're pointing it at then proxying is your best bet. Although personally i'd stick to using Nginx for the proxy rather than Apache's mod_proxy as mod_proxy isn't the safest unless configured well.

Did you sort this Bart?
I think I'm after a similar thing. Basically I've got X running on port 81, but at work port 81 is restricted. What I want to do is to be able to access X, I assume by routing through another port that is allowed like 80.

If you're setting it up yourself then Dom's advice to use Nginx is pretty sound, it's a great server. When playing about with Node.js in the past I used this sort of technique:

The same principles could be applied to proxy to something else though.

Ed, forgive me for being ignorant, but that's a lot of reading and I CBA. Is there a script or something I can just drag over to sort it for me?

Hmmm, don't think so You'll need to install Nginx onto a computer/server/VPS and then copy and paste most of that configuration over.

Depends what you are running?
If its sshd for example, you can just reconfigure the daemon to listen to a different/another port.

Apache.
I have a DVR running and it's using port 81 to login and 8101 as the control port. Work server blocks anything not on conventional ports like 80, etc. basically somehow I need to be able to access the DVR.

i dont know it it would work but couldn't you enable RDP onto a computer and translate the port to 80 on your firewall. never tried doing it with 80 before.

if the DVR is behind a router doing port forwarding, some routers let you change the port on the forward, so for example you could use port TCP/80 to forward to TCP/81 on the DVR and port TCP/443 (https) to port TCP/8101
Your work won't be blocking 80 or 443.

If its not behind a router/firewall then you can edit the httpd.conf (apache) to listen to another port, there should be a line like
code:
Listen 80
Just change 80 to the desired port number and restart apache.

If they have some standardish filtering/firewall it shouldnt be a problem, if they do deep packet inspection to check that it is indeed https/http going over the link, you could be fucked. Either way give it a go and let us know how you get on 
You spying on home during the day or something

It's actually for my dad so he can spy on his empire yes
Got cams all round the house and he works away a lot so would like to be able to check up on it from wherever and the server where he works won't allow dodgy ports, although strangely they allow it if he uses the same companies VPN from outside the office
Unfortunately I won't be able to try till later in the week since I'll have to do it at their house.
