Is there a way to have my dns computer tell a browser to go to a specific ip and port#

<problem>
I'm looking to change port# used to access my http server. It's listening on port80 but i would like to change it to another port#. I want to accomplish this from/using my dns computer

<my situation>
I have a single static ip (wan side) from my isp and a linksys router. One machine (redhat's valhalla) is dns bind 9.2.0. It is working from the lan side address 192.168.1.1 and is directing http to a second machine (apache2.0.47) virtualhosting from address 192.168.1.2. Dns is forwarded through the router via port53. Apache is working through port80 and the url's are on target

It's not a pressing problem. Just something I'd like to learn more about. Any help would be good

An old question, but the same answer...
in short, no... dns will only serve up numbers...

Thanks for replying Peter.

It's looking more like multiple wan ip addresses and a little iptable-ing to make it work. Would you care to share another way to do this?

First choice would be some non-masqueraded packet routing from a friendly external server to change the destination ports and address but not the original source address.
Your dns serves up the external address.
You need to have a spoofing SNAT entry in your own POSTROUTING to say it originated from the friendly server or the connections won't route properly.

Second choice for me would be an http page on an external server (eg Geocities) serving redirects to your virtual names.
This means your dns supplies one numeric host address and the client browser adds the character paths, eg http://66.218.77.68:/virtual/server which get redirected to the browser as http://virtual.url.no:81/pages/to/view by the http page.
People can then Bookmark the final address.

Third and most complete choice would be to set up an external proxy with the redirects.

For the last two, it would mean you do the dns to supply the external server address, but have to play around with the paths you advertise to match the paths you can get on the external server.

(And if the proxy/redirect is external, it kinda follows that some of the webpages are too...)
