DHCP relay over VPN tunnel to Azure

Hi all,

 

This is my current set up. I only have one physical (host) server (192.168.0.0/24) and a direct tunnel an Azure VM (192.168.3.0/24), serving as my secondary AD server, DNS, and DHCP. However, I'm unable to get clients from the 192.168.0.0 network to request an IP from the 192.168.3.0 subnet due to not being able to relay the DHCP requests over VPN. Is there a way to do this in the Netgeat FVS336Gv3 software? I need to have this config in order to ensure business continuity during the maintance of the host on the 192.168.0.0 subnet. Thanks in advance for your suggestions. --Suggesting another physical server on the 192.168.0.0 is not an option.

No. The solution on the other thread is not an acceptable solution. I want to know if the Netgear router can support DHCP relay for site-to-site VPNs.

@diegobaccino,

 

I'm afraid that it is not supported on the FVS336Gv3.

Re: DHCP relay over VPN tunnel to Azure

Hi All,

 

I'm currently using UDP DHCP relay on M4300-52G-PoE+ switch to point to a DHCP server in our network per VLAN interfcae, server itself is Windows 2012R2 VM. DHCP works perfectly fine.

Now, let's say I want to add another DHCP server for redundancy. Does anyone know if it is possible to have primary and secondary UDP DHCP relays? It seems I can add another entry for relay with a different DHCP server IP address, but it's not clear how it will prioritize (or load balance) DHCP requests between servers? I guess the goal is to use one DHCP server as primary and another one as a backup in case if primary is not responding.

Both Windows DHCP server will be setup in failover.

 

Thanks!

 

Regards,

Dmytro
