Description

In some circumstances the ruleset is not reloaded or regenerated after re-assigning an interface.

For example after reassigning the WAN from igb0 to lagg0 in the webgui and saving that the WAN interface is correctly switched and brings up an IP as shown in ifconfig:

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        description: WAN
        options=e138bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC,VLAN_HWFILTER,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 00:90:7f:da:44:72
        inet6 fe80::290:7fff:feda:4472%lagg0 prefixlen 64 scopeid 0x11
        inet 172.21.16.183 netmask 0xffffff00 broadcast 172.21.16.255
        laggproto lacp lagghash l2,l3,l4
        laggport: ix0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
        laggport: ix1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
        groups: lagg
        media: Ethernet autoselect
        status: active
        nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>

But the firewall is not usable because ruleset in place is still referencing igb0:

[2.6.0-RELEASE][root@m470-3.stevew.lan]/root: cat /tmp/rules.debug
set limit table-entries 400000
set optimization normal
set limit states 397000
set limit src-nodes 397000

#System aliases

loopback = "{ lo0 }" 
WAN = "{ igb0 }" 
LAN = "{ igb1 }" 

That can also be seen in the running rulset:

[2.6.0-RELEASE][root@m470-3.stevew.lan]/root: pfctl -sr | grep igb0

[2.6.0-RELEASE][root@m470-3.stevew.lan]/root: pfctl -sr | grep lagg0
[2.6.0-RELEASE][root@m470-3.stevew.lan]/root: 

Tested using a DHCP WAN where both igb0 and lagg0 are pulling leases from the same server.

Tested in 2.6. It does not happen in 2.5.2.

Confirmed this no longer happens in current 2.7 snapshots. The running ruleset is updated immediately when re-assigning the WAN.
