Hi guys, The IPv4 firewalls (I’m not using IPv6) were manageable until I upgraded to Webmin version 1.953 today. Please let me know what I need to look at and what to try so I can manage my firewall in Webmin again!
I check my firewalls list frequently so I am aware if Fail2Ban has been reacting to increases in attacks, and to add manual entries to block email spam sources. The upgrade fixed broken Lets Encrypt feature which I was about to come here to inquire about. The firewall rules consisted of a block of default rules generated by Virtualmin, followed by a block of my manual rules, and then several blocks of Fail2Ban rules. Every time I reboot the OS, I disable Fail2Ban and Save Configuration, and I did this several days ago. This image is all that I have now:

In the IPv4 Firewall config screen I tried to [Add a new chain named: test], but it tells me I’m not allowed to access:
I am logged into Virtualmin as root, and permissions for that iptables file are:
Thanks in advance for your help!
