Where are the clients and where are the servers? The clients will send from an ephemeral port number to port 23, the Telnet port. Their traffic will definitely hit that priority-list. Now we enter into the realm of poor documentation to answer the question about traffic coming from the server. Traffic from the server will use a source port of 23 and go back to the client's ephemeral port. Will that traffic also hit the prioirty list? Hopefully the answer is yes, but I have never found a definite word on this. Anyone know? Does a prioirty list look at traffic both to and from the port number specified? If yes, then add the command on both ends. Probably do it anyway for testing purposes since we may not get an answer to the question above. (There doesn't seem to be any way to test it since the show queu commands are so useless.) > the telnet connection will go through the Internet.

Telnet over the Internet with all it variable delay doesn't seem like a good idea for a mission-critical application (if it is mission-critical?) But you should put a protocol analyzer on it and determine if this is the case. The delay could very well be the application too. What is Telnet getting used for? With an analyzer you can see where in the flow of packets the delays are actually occuring. > 2.

I doubt that a tunnel would help, though I may not understand what you have in mind. The extra encapsulation required to tunnel will slow router processing down. Also, where does the tunnel go? Doesn't it cross the Internet too? Well, good luck with it. Please keep us posted.
