Server

$ mr2 server -l :9999 -p password

# Only allow partial ports, and set password on each port
$ mr2 server -l :9999 -P '5678 password' -P '6789 password1'

Client

# Local server is 127.0.0.1:1234, expect to expose: server_address:5678
$ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:1234

# Local web root is /path/to/www, expect to expose: server_address:5678
$ mr2 client -s server_address:port -p password -P 5678 --clientDirectory /path/to/www

Example

Access local HTTP server

$ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:8080

# then
Your HTTP server in external network is: server_address:5678

SSH into local computer

$ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:22

# then
$ ssh -oPort=5678 user@server_address

Access local DNS server

$ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:53

# then
Your DNS server in external network is: server_address:5678

$ dig github.com @server_address -p 5678

Access your local directory via HTTP

$ mr2 client -s server_address:port -p password -P 5678 --clientDirectory /path/to/www

# then
A HTTP server in external network is: server_address:5678
