Proxy DHCP ports

I was just trying to find out what ports the Proxy DHCP server listens for requests from? I thought that it was 4011, is that correct? UDP was another thought on my part. Can someone let me know if that is the correct information?

Thanks

Re: Proxy DHCP ports

According to the RFC:
The Proxy DHCP service may also run on the same host as the standard DHCP service. Since two services cannot share port 67/UDP, the Proxy DHCP runs on port 4011/UDP and expects the extended DHCPDISCOVER packets from PXE Clients to be DHCPREQUESTs. The standard DHCP service has to send a special combination of PXE options in its DHCPOFFER, so the PXE client knows to look for a Proxy DHCP on the same host, port 4011/UDP.

Re: Proxy DHCP ports

If it's "not" running on the DHCP server, then I believe it just binds to udp/67.
