+Subject: [PATCH] portblock: accept numeric protocol from iptables
+
+Usually, using the "-n" flag with "iptables -L" will only enable numeric
+display for hosts and port numbers. Protocols are unaffected and are
+still shown as "tcp" or "udp", which we rely on in the portblock agent.
+
+iptables version 1.8.9 ships with a regression that breaks this format,
+displaying the numeric value of the protocol instead. See this bug
+report for more: https://bugzilla.netfilter.org/show_bug.cgi?id=1729
+
+The issue was fixed in the 1.8.10 release, but some distributions
+(notably, Debian Bookworm and Fedora 39) have shipped 1.8.9,
+effectively breaking the portblock agent.
+
+Since both formats are now in use in the wild, we must work around this
+in the resource agent by allowing both the numeric and string
+representation of the protocol.
