    There are a few ways to do it, but you don’t use caddy for SSH.

    • host SSH on port 22, forgejo on a different port. Expose both ports to the internet
    • host SSH on a different port, forgejo on port 22. Expose both ports to the internet
    • host SSH on port 22. Forgejo on port 2222. Only 22 exposed to the internet. Change the authorized_keys user of the git user on host to automatically call the internal forgejo SSH app

    Last option is how I run my Gitea instance, authorized keys is managed by gitea so you don’t really need to do anything high maintenance.

    ~git/.ssh/authorized_keys:

    command="/usr/local/bin/gitea --config=/data/gitea/conf/app.ini serv key-9",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty,no-user-rc,restrict ssh-rsa PUBLICKEYHASH
    

    /usr/local/bin/gitea:

    ssh -p 2222 -o StrictHostKeyChecking=no git@127.0.0.14 "SSH_ORIGINAL_COMMAND=\"$SSH_ORIGINAL_COMMAND\" $0 $@"
    

    127.0.0.14 is the local git docker access where I expose the service, but you couldn’t different ports, IPS, etc.










  • I can’t remember all the details, but depending on the CPU you are running you may need some extra configuration on opnsense.

    There were a few issues, on my servers, running on older Intel Xeon CPUs, but I eventually fixed them adding proper flags to deal with different bugs.

    Other than that, running on a VM is really handy.











  • While I don’t use TPM myself (I dislike being tied to a specific hardware) the way it protects you is:

    Disk is protected through encryption, so you can’t remove and inject anything/hack the password.

    If boot is protected/signed/authorized only, a random person can’t load an external OS and modify the disk either.

    All this together would say, even if someone acquires your computer, they can’t do anything to it without an account with access, or an exploit that works before a user logs.

    In a way, the attack surface can be bigger than if you simply encrypted your disk with a key and password protect that key.
