I was unable to get the feed to update after a fresh install of the VM (version 6.0.7). I tried switching it to port 443 (from 24) but that didn’t seem to help either.
Ultimately, I had to get a firewall rule made to allow TCP access over port 873 to URLs: feed.openvas.org and feed.community.greenbone.net.
That was enough to make it work. I also added ports 24 and 443 for good measure because they are referenced in the architecture diagram. I also added the feeds mentioned below (apt.greenbone.net and feed.greenbone.net)
Feeds (see below)
- Direct
- Connecting to 24/tcp or 443/tcp
- Direct internet access required
- Via proxy
- Connecting to internal HTTP proxy supporting CONNECT method on configurable port
- Connecting to apt.greenbone.net and feed.greenbone.net
- Mandatory on stand-alone and master appliances
- Used protocol is SSH
- Encrypted and bidirectionally authenticated via SSH
- Server: public key
- Client: public key
