I've noticed several issues with using the OMV "firewall" :
- If entering manual "firewall" rules in the firewall section, it will delete rules inserted by the fail2ban plugin, which will defeat fail2ban completely.
- One cannot restore them manually, as the "firewall" module doesn't accept a target being another chain. Only "ACCEPT" "DROP" "REJECT" are accepted, which is far to little.
- When entering iptables rules, the interface happily accepts them an lists them ; however, once applied, a console "iptables -vL" shows that some rules that the interface happily accepted were not applied at all, and are just missing without any error notice.
- How would I be supposed to enter such a rule in INPUT :
These are the kind of rules that I seem unable to enter...
TIA, kind regards.
