For clarity, here's my test cases
I've two services that bind to the same service provider.
The first service defines an interceptor for 'test.test' port 811. I can telnet test.test 8111 and it works. But this is not available from other machines on my local network.
I want to use the second service as telnet localhost 8111, but I can't figure out how to set up the interceptor to make this happen. If I can get this working I ought to be able to open port 8111 in my firewall for use by other hardware on my local network.
