1.33 adds this change:
"inbound NAT rules can now be added on the LAN interface with the WAN address as a target; this
helps with accessing servers on an optional interface from the LAN interface by using m0n0wall's WAN
Does that literally mean ONLY optional interfaces, and that a LAN->WAN IP->LAN connection is still
not supported? Does "target" mean the "NAT IP" field in the firewall rule edit page?
Overall I saw some odd behavior when experimenting with this, which may have been me shooting myself
in the foot. :) I added a NAT rule on LAN for HTTPS to point to a WAN IP, and when saving I lost
connection halfway through the page load, but was immediately able to reconnect. (It probably
didn't help that I was connected to m0n0wall using HTTPS at the time.) However I then edited that
rule, and though my change was recorded (but not yet Applied) all the firewall rules had been
erased/lost, but I could restore from backup.
