Was there a conscious decision in omitting a link to the IPtables info from the following?
The Web Interface / Firewall Documentation
https://wiki.ipfire.org/configuration/firewall
I found the link to this IPTables Wiki info when doing a search.
The Web Interface / Firewall Documentation / IPtables
https://wiki.ipfire.org/configuration/firewall/iptables
I thought it was odd there being no link / reference from what appears to be the parent page.
