For the record I am running a mesh configuration of an AX88u main router on Merlin 386.3_2 and an AC68u as a mesh client running on stock 3.0.0.4.386_46065. Also a Open vpn server is active on the AX88u.
According the change log for 386.3_2 , dnsmasq version 2.85-openssl is used.
In the Asus Gui DHCP lease time is set as :
I just noticed a odd behavior of the DHCP lease time when monitoring the dnsmasq logfile.
In dnsmasq.conf the lease time is set as :
When looking at the dnsmasq logfile, I grabbed for DHCPREQUEST for one client:
The time between these requests is not 16m as expected but only 8m.
When changing the lease time in the ASUS GUI, dnsmasq will always use half of the set lease time for a DHCPREQUEST!!
Something similar is going on in the Asus Gui.
Looking at the DHCP leases log , it will start at 16m and counting down, but will not go down below 8m!

Can anyone else confirm this odd behavior in the newer firmware (updated dnsmasq ) or is it as intended?
