client reponse ports for asp.net

[Raterus]

If I remember correctly from my networking class, the client OS sets these, not the server. If the server set them, how would the client know on which port to listen for the response?

This makes a lot of sense this is what my net admin is telling me.

I allways asumed that my response to the client allways went back on the port the request was issued. However, my network admin is asking me to set the range of ports my web app response. So I asked is the reponse not comming back on port 81 (our local intranet) and he said no. He has been monitoring the port requests and reponses form our web server and said that the web server is randomnly using a port to respond back to the client. In this case to talk to the web server client 1.1.2.1 send a request to server 1.1.1.1:81 the response the server is sending is 1.1.2.1:## where ## seems to be a random number between a certain range of ports.

He needs me to set this range of ports in the high end for security purposes.
So if it is a client setting how can we set our clients which are only computer inside our private network to only listen for the reponse on a specified port range?

thanks your response is very valuable
