Can I use FRTS or ACL's on a 2509 via the ports that traffic goes thru?
I have TNPP (paging protocol) that sends alpha/numeric messgaes from a remote Paging terminal thru a 2509 and out the WAN interface. There are dedicated ports (from the terminal to the router) for customer messages, stat info, and alarm messages all using the same protocol. I want to manage bandwith via FRTS/ACL. Can I create an ACL based upon the 2509 port that the portocol goes thru?

This should be possible. We map the physical line number into the low-order 9 bits of the source TCP port number. E.g. when I telnet from line 3 my source port number is 33795 (decimal) which I AND with 0x1FF giving 3.
