Different DUID for different WAN interfaces

[Cloud]

Hello OPNSense,

I have a cable modem with 3 WAN interfaces. My cable provider allows me to pull 3 IPv4 WAN IPs and a /60 max on each unique DUID. I have two WANs connected to my OPNSense from the cable modem. I can pull one IPv4 on both, but I can't pull IPv6 for both since the DUID IPv6 identifier is the same.

Is there any way I can make the DUID different on one WAN interface and different on the other? One /60 is exceedingly not enough for me.

dhcp6c only supports one DUID. It supports multiple WAN interfaces but your ISPs config is a bit unusual.
