Not sure what is going on at all here, probably an IPv6/NAT issue but I can’t narrow it down after hours of troubleshooting and Googling.
I am using IPv4 only on my network but there are no outbound rules in place to stop my server from connecting to the internet.
Running the following fails:
nc -vvv feed.openvas.org 873
But running this does not:
nc -vvv feed.community.greenbone.net 873
I have tried netcating directly from my FW’s public interface as well and have the same outcome, so to me that rules out NAT or FW rules.
I cannot ping the address either from any device, but it does resolve to with both an ipv4 and ipv6
There are no other devices running rsync that have any issues.
Purged states on interfaces before trying.
Anyone have any ideas?
