DHCP relay type REGULAR or IPSEC

[RDY77]

Hello all.

Can somebody explain me what's the difference between the two DHCP relay modes?

I've spokes connected to hub via DIALUP IPSEC VPN.

DHCP server is behind the hub.

In the spoke vlans I configured DHCP relay feature.

I don't understand if I need to configure in REGULAR or IPSEC mode.

Many thanks.

I can't tell you what the scenario is exactly for using IPSEC mode, but I can say that my DHCP relay works fine using regular mode with the same topology you just described.
