DDNS Update with Public IP for cellular interface don't work bug

PeterUK

VPN300 V5.36(ABFC.2)

With a DDNS setup for cellular1 interface there is no update check happening to site check like:

http://ip1.dynupdate.no-ip.com/

Which should check every 5 minutes

However other interfaces for DDNS do check every 5 minutes just not cellular1 interface.

Ok solved it!

So I have a routing rule:

incoming ZyWALL

service HTTP

next hop VLAN443

I have DDNS going out VLAN 443 and ge4 the HTTP check works fine regardless of the above rule but not for the cellular1 so I made this rule above the rule above:

incoming ZyWALL

source address 192.168.8.100

service HTTP

next hop cellular1

Now it works
