Small interface type bug with general on boot up to SNAT traffic
V4.72(AAAA.0)ITS-22WK28-r104687
In order for the Zyxel devices to connect to the internet they must use VLAN443 and SNAT to OPT
Normally the VLAN443 would be set to external but changed to general for testing DHCP
On rebooting the USG40 and Zywall 110 I found the USG40 on service license refresh failed but Zywall 110 service license refresh was fine when I changed the interface type for VLAN443 to external on the Zywall 110 the USG40 could get the service license refresh then changed it back to general it still worked so only on a reboot dose this happen.
Here is a cut down setup

Hi @PeterUK,
Can you help to check if the routing information of cli Router> debug system ip route show table default-wan-trunk is same after device reboot?0 -
After reboot and the issue happened when VLAN443 set to generalRouter# debug system ip route show table default-wan-trunkdefault mpath LLF-totalnexthop via 192.168.44.2 dev vlan443 weight 1nexthop via xxx.173.xxx.1 dev eth2 weight 1
Then changed to external and working
Router# debug system ip route show table default-wan-trunkdefault mpath LLF-totalnexthop via 192.168.44.2 dev vlan443 weight 1nexthop via xxx.173.xxx.1 dev eth2 weight 10 -
With some testing help from Zyxel_Cooldia the reason why was the DHCP setting is not setup (set to none) on the Zywall 110 but Enable IP/MAC Binding was checked so on a reboot for some reason it blocks the traffic but changing the interface type allows traffic or uncheck Enable IP/MAC Binding.
