Hi, I am not sure if I get your question. If you bind the listening socket to localhost:8888 it is bound to the (IPv4) loopback interface, which is of course only reachable from the local host.
If you want to bind to all interfaces, you would have to use mllp:0.0.0.0:8888 (which would mean all IPv4 interfaces, though I have no clue if this works with MLLP). If you use HOSTNAME, you will bind to the externally reachable remote interface, which is reachable externally. Best regards Stephan -----Original Message----- From: John F.

If I use hostname, it works fine. from("mllp://HOSTNAME:8888") This works from("mllp://localhost:8888") this doesn't (for the external system anyway) Is this a limitation of the mllp package I'm using, or just "nature of the beast" camel behavior. I'd like not to have to specify hostname explicitly so I can run this on any machine I execute it on. I assume it's exposing the port with the explicit hostname, since it has to resolve it "further out" on the networking level than localhost? Thanks!
