Draytek2926AC Port Redirection fails when Failover activates

[JDDD]

I have a DrayTek 2926ac router that has an Ethernet feed as it's primary WAN and a 4G router (factory default settings + APN) as the Failover WAN.

I also have Port Redirection set up.

When I disable the primary WAN, the failover WAN activates and the internet is restored HOWEVER the Port Redirection fails.

When I restore the primary WAN, the Port Redirection also comes back.

Anyone know if this is a design flaw?

Or does someone have a workaround?

Thanks!

page 106 for WAN failover settings, page 142 for Port redirection. What does your port redirection config page look like?

on page 144, there's a screen shot of the Port Redirection config, looks like each Port redirection rule can have a WAN defined, default is "all"



Also, you could try submitting a support ticket: https://www.draytek.com/support/contact/

I don't have any experience with draytek, not sure how prompt they'll be.
