You need to enable RSYNC (TCP/873) without NAT and Proxy to our IPv6/IPv4 feed server [feed.community.greenbone.net] . SSH port 24 or 443 is only supported if you use the GSF (Paying Greenbone Customer). You should check with your firewall that a connection is active. Please note if you share your IP with other Systems one feed-sync per IP is the limit for the GCF. You can check by telneting to the Port 873 if your communication works.
You will see:
#nc6 feed.community.greenbone.net 873
