Adjust WAN DHCPv6 Send or Request Options? Lease time?

[the1corrupted]

Hello,

I am trying to find ways to adjust the DHCPv6 options in the same way you can change the DHCPv4 timings in OPNSense

All I see are "Send Options", and "Request Options"

For DHCPv4 there are various timing options.

Right now, I feel like the DHClient on the WAN interface is rolling too frequently given that the v4 lease is 3600 (3 days) and it's going every couple hours, spurts for a few minutes in a row then quits.

DHCPv6 is setup as:
* Request prefix only
* (Optional) Interface ID is 1
* VLAN Priority 0
* Prefix Delegation Size 60

LAN is set to TRACK WAN interface.

My existing OPNSense system was updated many many times. The last time I did a full re-install was 24.1 so I decided to completely reinstall and reconfigure for 24.7 just in case something silly would come up

After completely re-installing the OS, I get the same issue. DHCP6 script is running every couple minutes when I'm certain it doesn't actually need to.

I'm just wondering if there are any options to slow it down to an hour or a day?

After much further research, there does not appear to be a good client-side solution to implement for IPv6.
