DHCP on RED and GREEN

[Guest]

Hi Community,

I am facing follwing issue at the moment:
For some reasons my Internet-router (on red) has to distribute IP Adresses via DHCP. Furthermore my endian has also distribute ip-adresses for all my "usual" network devices on green.

Does someone has an idea, how this should work in my situation? Is it generally possible to block dhcp requests from green devices to the red dhcp (or in the other direction)?

My idea was to block upd traffic of ports 67 and 68 from the router ip () on red to the green interface/network.

Or does someone has a better idea?

Thanks in advance and best regards

if you're not NATTING your router, it can't distribute DHCP behind Endian

oh damn - I think I have found my problem. It was obvoisly a problem with my VLAN configuration on my uplink - switch

Problem is fixed now and working as intended (and described).
