Hello,
I’ve been trying to get DHCP working via AdGuard Home running inside a container on my Proxmox host (PVE). The DHCP Discover requests are correctly received, and Offers are generated. I can see the DHCP Offers on the ens88p0 interface using tcpdump, but these offers do not seem to leave the PVE host.
To troubleshoot, I’ve attempted to broadcast a UDP packet using netcat from within the Proxmox Host:
- This is not seen outside the host.
- This is seen, along with other ports I’ve tried (everything except port 68).
There are no firewall rules or services binding port 68, and I can successfully see UDP port 68 traffic when generating it outside the Proxmox host.
I’m currently stumped on why UDP port 68 is being blocked when attempting to send packets from Proxmox. Any help or insights would be greatly appreciated!
Thanks,
Justatree
