ASA DHCP Relay

[rmeans]

I am moving a network from a n7k to an ASA.  With the network on the ASA, the clients on the local subnet are not getting IP addresses from the DHCP server.

Years ago, I moved the network a 6500 to the N7k.  I recall adding "ip dhcp relay subnet-broadcast" to the n7k SVI to make DHCP to work.  I am now trying to move the network from the n7k to the ASA.

On the ASA...

interface net995
 description netmotion
 nameif net995
 security-level 70
 ip address 172.18.0.1 255.255.0.0 standby 172.18.0.2

dhcprelay server 192.168.200.14 outside
dhcprelay server 192.168.200.15 outside
dhcprelay enable net995

Other networks needing DHCP are working correctly.  I can't help but feel the ASA is missing something similar to the n7k from years ago.

Hi,

I think you can try and configure this command and see if it makes any difference:-

dhcprelay setroute net995

Hi,

In that case , I think you would need to capture the traffic on the ASA device for the DORA process and debugs to look into this issue further.

Thanks and Regards,
