It seems that hestia rewrites the rules on reboot and I had to wipe the server because I used iptables-save. Hestia would no longer add its rules so I was stuck with generic rules.
[1] I am wanting to allow two IPs with no restrictions. The Hestia web interface will not allow that.
iptables -I INPUT 2 -s 100.113.77.38 -j ACCEPT
iptables -I INPUT 1 -s 107.91.12.23 -j ACCEPT
[2] Once I have another DNS issue resolved, I am going to add a second static IP to this machine which should be eth1. Will the Hestica CP pass port 53 to both IPs? I have done many linux servers on the years, but this will be the first one with more than one static IP.
ACCEPT tcp – 0.0.0.0/0 0.0.0.0/0 tcp dpt:53
