Re: Firewall blocking my new Debian 11 server ports 80 and 443




ssh gives me a login prompt


Btw, I highly recommend:
* Block SSH access from any IP except one you are going to use to manage this server
* If you have dynamic IP, you can add all your ISP network, or, at least, your country: (list can be downloaded here https://blog.ip2location.com/knowledge-base/how-to-block-ip-addresses-from-a-country-using-ipset/)
* Deny password access and use keys only (use EdDSA, not RSA if possible). Passwords should never be used
* Disable root access
* Get rid of SHA-1 and other weak things: https://sshcheck.com/server/69.30.225.10/

You have your ssh server opened to the whole world and there are zillions of bots trying to guess your password now.
