Hello,
I need some help to configure correctly the dhcp relay with vlan.
In fact, I can get address with DHCP in my vlans, but only from the 1st interface configured and listed in the 'DHCP Relay Interface Settings'
The Dhcp Server is Windows Server 2012R2, ip 192.168.100.1 in SRV Vlan. Scopes are configured for ranges 192.168.10.0/24 (ASI) and 192.168.50.0/24 (SAD)
With Statics IPs, everything is pingable from everywhere.
Here is some experiments with the relay agent :
Interface Server 1 Server 2 Server 3 Server 4
------------ --------------- --------------- --------------- ---------------
ASI 192.168.100.1
SAD 192.168.100.1
Only PCs in VLAN 'ASI' will get address via DHCP
Pcs in SAD Vlan never get a response from the relay. wireshark on PC and dhcp server show that the request is effectively received by the server, it sends back an offer via the relay, but the pc never sees anything back from the relay
Now, if I remove the ASI interface from the relay settings, thus having :
Interface Server 1 Server 2 Server 3 Server 4
------------ --------------- --------------- --------------- ---------------
SAD 192.168.100.1
Pcs in VLAN 'SAD' now get offers via DHCP !!!!
I think I have missed something obvious, so any help or advice will be greatly appreciated !
Thanks!

- What region are you located?
Is there any information in the user manual regarding this?
-
We are located in Europe > France
There is no such restriction in the user manual concerning the number of interfaces that can be relayed via the DHCP Relay Interface (WEB_UI reference , chapter 10, CLI_Reference chapter 22-2)
-
Any status on this? ???
You might want to phone contact your regional D-Link support office for help and information regarding this.
