Be correct on teh variable scope
Another try at prventing panic on reconfig of ppp type wans. Ticket #1696
If we are coming from a PPPoE/PPTP WAN type, grab the old physical interface first to avoid assigning a ppp interface to itself. Fixes pppoe->pppoe wizard run as well as changing pppoe->dhcp. Fixes #1696
Add no cache header
Fixes #1696. Do not store temporary information under interfaces section during wizards since this might generate a message to netgraph that triggers a panic.
Don't try to unset this variable if it isn't set to begin with. Fixes #1865
fix firewall_nat_out to not auto-generate outbound NAT rules with one too many IPs
