Socket Pipe can forward your socket from one address to anoter without any configs. It supports both tcp and udp, you can simplely make a software net-bridge.
npm install -g socket-pipe
The following example shows how to map a remote address (ip=192.168.1.100 port=80) to a local address (ip=127.0.0.1 port=80) via tcp tunnel.
socket-pipe -l 127.0.0.1@80 -r 192.168.1.100@80 -t tcp
The following example shows how to map a remote address (ip=8.8.8.8 port=53) to a local address (ip=127.0.0.1 port=53) via udp tunnel.
socket-pipe -l 127.0.0.1@53 -r 8.8.8.8@53 -t udp
The following example shows how to map a server from LAN (ip=192.168.1.100 port=80) to internet (ip=123.123.123.123 port=80).
socket-pipe -l 192.168.1.100@80 -r 123.123.123.123@10080 -t tclient
socket-pipe -l 123.123.123.123@10080 -r 123.123.123.123@80 -t tserver
The following example shows how to map multi http servers from LAN (ip=[192.168.1.100 - 192.168.1.102] port=80) to internet (ip=123.123.123.123 port=80).
http1
socket-pipe -l 192.168.1.100@80 -r 123.123.123.123@10080 -t hclient -x git.dev.com -s git
http2
socket-pipe -l 192.168.1.101@80 -r 123.123.123.123@10080 -t hclient -x file.dev.com
http3
socket-pipe -l 192.168.1.102@80 -r 123.123.123.123@10080 -t hclient -s wiki
socket-pipe -l 123.123.123.123@10080 -r 123.123.123.123@80 -t hserver
There are two special params.
-xmeans socket-pipe will transform:- The
Hostvalue in http request header. - The host part of 'Location' value in http response header.
- The
-smeans specify a domain prefix. The server side will create a random prefix without specifying.
Now you can visit different backend http server in a LAN from a portal on internet.
For example if domain *.test.com is pointing to 123.123.123.123, the visits to http://git.test.com/ will be forwarded to http://192.168.1.100/ with host git.dev.com because of the domain prefix git.
