Chisel Port Forwarding

Chisel supports three types of port forwarding

local Port Forwarding

Local port forwarding allows you to forward a port on the client machine to a port on the server machine or a remote destination

Example :

Forward local port 1337 to 127.0.0.1:1337 through a remote chisel server:

chisel client 10.10.14.6:8000 R:1337:127.0.0.1:1337

In this case:

  • 10.10.14.6 - Chisel server IP

  • 8000 - Chisel server port

  • R:1337:127.0.0.1:1337 - Forwarking local port 1337 to remote `` 127.0.0.1:1337

Remote Port Forwarding

Remote port forwarding allows you to expose a service running on the client machineto the Chisel server, whichmakes it accessible to other clients connected to the server:

Example:

Forward Remote port 8080 ro local 127.0.0.1:8080:

chisel client 192.168.29.218:80 R:8080127.0.0.1:8080

In this case:

  • 192.168.29.218 : Client server IP

  • 80 : chisel server port

  • R:8080:127.0.0.1:8080 : Forward remote port 8080 to local 127.0.0.1

Forward remote port 22 to local 22:

chisel client 192.168.29.218:8000 R:22:127.0.0.1:22

  • 192.168.29.218 : Client server IP

  • 8000 : chisel server port

  • R:22:127.0.0.1:22 : Forward remote port 22 to local 22

Forward remote port 80 to remote host:

chisel client 192.168.29.218:8000 R:80:10.0.0.100:80

  • 192.168.29.218 : Client server IP

  • 8000 : chisel server port

  • R:80:10.0.0.100:80 : Forward remote port 80 to local 10.0.0.100:80

Windows Client Example

Forward remote port 80 to local 80 using a windows client

chisel.exe client 192.168.29.218:21 R:80:127.0.0.1:80

  • 192.168.29.218 : Client server IP

  • 80 : chisel server port

  • R:80:127.0.0.1:80 : Forward remote port 80 to local 80

Dynamic Port Forwarding

Dynamic port forwarding creates a SOCKS proxy, which allows the client to tunnel traffic dynamically o multiple destinations through the chisel server

Example: Create a SOCKS proxy on local port 1080:

chisel client 192.168.29.218:8000 R:socks

  • 192.168.29.218 : Client server IP

  • 8000 : chisel server port

  • R:socks : set up a dynamic SOCKS proxy on local port 1080
