I know how enable DHCP (Local and Gateway DHCP) on segments. And everything is working if DFW is ALLOW for ALL traffic.
Unfortunately communication between workload VMs and DHCP server (running on segment) stop working when we configure REJECT on default layer3 rule.
How should looks like rule which will open traffic only for this DHCP server and where should i put this ? I tried many combination for now without success.
Can you please explain what are you looking to achieve?
You have an on-premises DHCP server that will be leveraged by many segments on VMC with Relay DHCP, right?
In my specific case i prepared training class for our internal purpose. We don't have onpremise datacenter.
Haw can we reconstruct this issue:
1. Created 1 segment with enabled Local DHCP enabled (or can be also Gatewal DHCP nevermind)
2. Deployed 1 Windows Machine inside this segment.
VM (inside VMC) can receive IP from DHCP (enabled on segment) if default rule in Distributed Firewall Rule is configured to ALLOW. If this rule is configured to REJECT then VMs can't connect to DHCP.
I tried different types of FW rule without success. Maybe some suggestion how use this VMC DHCP in this scenario ? 🙂
