So, I have a script setup to automatically open a SSH connection to my server, and reverse port forward a port to me for SSH connections to my home desktop. This script has always worked until now that I've migrated servers.
The short of it is that I can't get this connection to bind on the external IP address, and I'm not sure why.
The script basically runs this command (I can confirm that this command with my values subbed in has the same result when run from a shell):
sudo autossh -M 5114 -D 7474 -R servers_public_ip:2695:localhost:22 -i /home/user/.ssh/id_rsa2 remote@servers_public_ip
When I check
lsof, I see the following connections bound for the
sshd 27570 remote 3u IPv4 161761 0t0 TCP servers_public_ip:22->67-213-103-227.eastlink.ca:62812 (ESTABLISHED) sshd 27570 remote 7u IPv6 161773 0t0 TCP ip6-localhost:5114 (LISTEN) sshd 27570 remote 8u IPv4 161774 0t0 TCP localhost:5114 (LISTEN) sshd 27570 remote 9u IPv6 161777 0t0 TCP ip6-localhost:2695 (LISTEN) sshd 27570 remote 10u IPv4 161778 0t0 TCP localhost:2695 (LISTEN)
None of these bindings are on the servers public ip, save for my ssh connection to the server to run lsof. This worked fine on my old server. I've checked sshd_config and turned on
AllowTcpForwarding explicitly. I'm running out of ideas.
