ports closed in dmz and ufw closed

de flag

I have problems opening ports on my Ubuntu 18.04.

  1. I put my PC in dmz to avoid router forwarding problems.
  2. I stopped ufw
  3. I look for listening ports on netstat: tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1464/sshd
  4. from port scanning webs port 22 seems closed.

Router dmz config:

router dmz config

In your *tag* you mention 18.04, but in the question you specify 18 (or a *specialist flavor* of Ubuntu 18.04 LTS Server). Please be precise with details, as 18 & 18.04 are different Ubuntu products. Which server product are you using?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
