Allow DHCP Server

[hungdnv9]

Hi Everyone,

I'm setup SoftetherVPN server on Linux Server, and create a local Tap Device, bound DHCP server on Tap (tap0) device.
If I disable CSF, client user can get IP by DHCP normal. But when enable CSF, client can't request an IP.

So, how do i allow DHCP on CSF? I have also allow dhcp IP range on csf.allow but nothing change.

Thanks for your help, guys.

I'd recommend starting with opening ports 67 & 68 via UDP.
