In an HA configuration (active-passive) XG 230 (SFOS 17.5 MR4) it can take 3 to 5 minutes for clients to be able to access the Internet.
As a detailed symptom, the IP address of the client is issued from the DHCP server but is in a state where it can not access the Internet.
There is no response even if I ping 8.8.8.8.
Even if you can not access the Internet, there is a response from the XG WAN interface.
The DHCP server is NETGEAR L3SW, and two HA link ports are connected via NETGEAR L3SW.
Enabling dynamic routes in all zones did not improve, and we compared whether there was no difference between when the ARP table and routing information were not accessible to the Internet and when they were available, but there was no difference.
I set HA according to the procedure described in the following page, and I think that there is no problem in the setting contents.

How can I solve it?
