server and client

On remote server. Note that the firewall opens TCP and UDP on all relevant ports

$ mr2 server -l :9999 -p password

More parameters: $ mr2 server -h

On local. Assume your remote mr2 server is 1.2.3.4:9999, your local server is 127.0.0.1:8080, want the remote server to open port 8888

$ mr2 client -s 1.2.3.4:9999 -p password -P 8888 -c 127.0.0.1:8080

More parameters: $ mr2 client -h

Then access 1.2.3.4:8888 equals to access 127.0.0.1:8080

Example of server and client

Expose local HTTP server

$ mr2 client -s 1.2.3.4:9999 -p password -P 8888 -c 127.0.0.1:8080

Then access 1.2.3.4:8888 equals to access 127.0.0.1:8080

Expose local SSH

$ mr2 client -s 1.2.3.4:9999 -p password -P 8888 -c 127.0.0.1:22

Then access 1.2.3.4:8888 equals to access 127.0.0.1:22

$ ssh -oPort=8888 [email protected]

Expose local DNS server

$ mr2 client -s 1.2.3.4:9999 -p password -P 8888 -c 127.0.0.1:53

Then access 1.2.3.4:8888 equals to access 127.0.0.1:53

$ dig github.com @1.2.3.4 -p 8888

Expose local directory via HTTP

$ mr2 client -s 1.2.3.4:9999 -p password -P 8888 --clientDirectory /path/to/www --clientPort 8080

Then access 1.2.3.4:8888 equals to access 127.0.0.1:8080, web root is /path/to/www

Expose any TCP/UDP service

...

httpsserver and httpsclient

On remote server. Assume your domain is domain.com, cert of *.domain.com is ./domain_com_cert.pem and ./domain_com_cert_key.pem, want https listen on 443. Note that the firewall opens TCP on all relevant ports

$ mr2 httpsserver -l :9999 -p password --domain domain.com --cert ./domain_com_cert.pem --certKey ./domain_com_cert_key.pem --tlsPort 443

More parameters: $ mr2 httpsserver -h

On local. Assume your remote mr2 httpsserver is 1.2.3.4:9999, your local HTTP 1.1 server is 127.0.0.1:8080, want the remote server to open subdomain hey

$ mr2 httpsclient -s 1.2.3.4:9999 -p password --serverSubdomain hey -c 127.0.0.1:8080

More parameters: $ mr2 httpsclient -h

Then access https://hey.domain.com:443 equals to access http://127.0.0.1:8080
