General purpose openconnect client docker container, which allows SSH tunnels from your local host to a remote host.
docker build -t openconnect-client .
docker run -ti --rm --privileged -p 4122:22 --volume $(pwd)/vpn:/vpn/ --name openconnect_client openconnect-client https://vpn.mynet.info:4443
you can also use DNS for the remote network, just add the DNS server information when starting the container:
--dns 10.11.12.10 --dns-search company.net
after that login into container and ping the host name to test if it works
now you can create an SSH tunnel to a remote host, or create SOCKS tunnel, to the destination network
example for RDP:
ssh -o PreferredAuthentications=password -L 192.168.31.10:33890:10.11.12.1:3389 -N root@localhost -p 4122
| local host IP: | 192.168.31.10 (optional) |
| local host port: | 33890 |
| remote host: | 10.11.12.1 |
| remote port: | 3389 |
after that enter password 'root'
example for SOCKS:
ssh -o PreferredAuthentications=password -D 58080 -C -N root@localhost -p 4122
-D: Tells SSH that we want a SOCKS tunnel on the specified port number
-C: Compresses the data before sending it
-N: Tells SSH that no command will be sent once the tunnel is up
the last port is the login to docker container over SSH using root user on port 4122 after that you need to enter the 'root' password
