+## Gsocket
+
+[Global Socket](https://www.gsocket.io) allows two workstations on different private networks to communicate with each other. Through firewalls and through NAT - like there is no firewall.
+
+### Simple port forwarding
+
+Forward the TCP connection to `workstation` on port 8080 to the remote network to host 192.168.1.1 port 80.
+
+```bash
+# Host on the remote network
+gs-netcat -s AnySecretChangeMe -l -d 192.168.1.1 -p 80 #-D
+```
+
+```bash
+# Your workstation
+gs-netcat -s AnySecretChangeMe -p 8080 #-D
+# Test the connection
+curl -v http://127.0.0.1:8080
+```
+
+### Dynamic port forwarding
+
+```bash
+# Host on the remote network
+gs-netcat -s AnySecretChangeMe -l -S #-D
+```
+
+```bash
+# Your workstation
+gs-netcat -s AnySecretChangeMe -p 1080 #-D
+# Test the socks connection
+curl -x socks5h://0 ipinfo.io
+```
+
+The `-D` switch can be used to start gs-netcat in the background.
