I have set up a web camera on my mikrotik home network, but my wife cannot view it at work because they have all outgoing ports except for 80 blocked. If I map 80 to the webcam she can see it fine, but I would rather not dedicate and expose the camera as the homepage on port 80 to the outside world.

To complicate things a little, my home network does not have a fixed IP, so I have to use ddns, and have setup no-ip.com to work successfully. So http://myddnsname.ddns.net/ succesfully accesses my network. I have various ports exposed to the outside that successfully forward to different devices on the network.

What I would like to do is redirect all requests to a specific url so that they maps to a specific server/port (the camera) on my network, eg http://myddnsname.ddns.net/camera transparently connects to 192.168.1.250:25081

This way, as far as my wife's employer is concerned, only port 80 is being used on her side, and on my side, I can direct traffic to different internal appliances/ports based only on the URL, all coming through the port 80 that is exposed to the world.

Is this practical?

Thanks,
BP

This isnt a mikrotik configuration problem, it is a web server configuration of getting content from another machine on the LAN and displaying it.
