Block secure (port 443) access to previous versions of MAIB while PHP exploit assessed?

Hi, what would be the firewall command to add a block of port 443?

Tried sudo ufw insert 1 deny 443 but it refused to insert a rule.

TIA!

root@box:~# ufw insert 2 deny 443 Skipping inserting existing rule Skipping inserting existing rule (v6) root@box:~# Not working as you showed. It appears that you need to sudo ufw status numbered then delete the two rules for port 443 using sudo ufw delete # once for each appearance … then you can do sudo ufw insert 2 deny 443

Thanks for the reply.

Possible to be a bit clearer and add a few linefeeds in your post?

Thanks!

The link preview does look horrible indeed, I agree.

You clicked the link, right??? Or expanded with the little chevron in the upper right corner of the preview box. It is much better to follow the link as the info the OP posted is needed as well.
