subdomain to multiple ssh servers
I've done a search, but I'm struggling to find who else has this problem. I'd like to be able to ssh into multiple servers behind pfSense using subdomains. So, essentially:
ssh to ssh1.example.com --> ssh server on server ssh1
ssh to ssh2.example.com --> ssh server on server ssh2
I would prefer not to use a single ssh server (or ssh'ing into pfSense) and then ssh'ing into ssh1, ssh2, etc. I also don't want to use a VPN because I want to minimize the overhead.
Is this possible please?
I'm running HAProxy as a reverse proxy. My webservers work really well, but not sure how to do this for ssh.
Thanks in advance.
