I'm able to SSH into 223.32.11.43 and cURL other servers on it's local network.
This works when I'm SSH'ed into :
curl -d '{my: parameter}' -H "Content-Type: application/json" 10.0.30.10
{code:200}
On a remote server I've setup a SOCKS tunnel with:
ssh -f -N -D 9090 MyUser@223.32.11.43
I've tried to setup iptables so I can cURL internal servers on the same network as the remote server:
iptables -t nat -A OUTPUT -s 10.0.30.10 -p tcp --dport 80 -j DNAT --to-destination 223.32.11.43
But it seems to fail, at least it times out with I try to cURL:
curl -d '{my: parameter}' -H "Content-Type: application/json" 10.0.30.10
...timeout
What do to, so I can do the same cURL on my remote server?
This worked for me:
From your remote computer, set up the SOCKS SSH tunnel to the remote server:
ssh -D 9090 -f -C -q -N MyUser@remote.ip
From the remote computer, issue a request over the tunnel:
curl -d '{my: parameter}' -H "Content-Type: application/json" \
--socks5-hostname remote.ip:9090 10.0.30.10
