Function

Remote → Local TCP connection

$ ./mudcat tcp --local-port 80 --remote-port 18080
[INFO]  Device UUID: a651d313-ab90-f786-a376-ab2078d1e22b
[INFO]  Access Connetion UUID: 6dd5726e-a08f-4322-b95f-8004c1de442f

[INFO]  Access Domain TTL: valid for 8.00 hours
[INFO]  Forwarding: TCP 306-451-3383.mudcat.io:18080 -> 127.0.0.1:80

When accessing remote TCP port 18080, open a tunnel to connect to localhost TCP 80. A remote access node is assigned automatically. In this example, a connection was created with the domain 306-451-3383.mudcat.io.

Remote → Local HTTP connection

$ ./mudcat http --domain test
[INFO]  Device UUID: a651d313-ab90-f786-a376-ab2078d1e22b
[INFO]  Access Connetion UUID: 944fb3d7-b0d5-40e4-a6b1-a15ba337ab44
[INFO]  Access Domain: test.mudcat.io
[INFO]  Access Domain TTL: valid for 24.00 hours
[INFO]  Forwarding: HTTP http://test.mudcat.io or https://test.mudcat.io -> 127.0.0.1:80

HTTP services can be easily shared externally. You can specify the name you want by using the --domain option.

Remote → Remote TCP connection

$ ./mudcat tcp --local-addr 104.107.104.228 --local-port 443 --remote-port 18085
