ASA DHCP Relay configuration

  • 772

I'll make it simple,

I have locations in different cities, connected using 2 Cisco ASA devices.

my main location, corporate, use the IP 192.168.1.x The second location, remote store, use the IP 192.168.3.x

I have a DHCP server (192.168.1.254) at my corporate location. I have created a scope for the 192.168.1.x which works fine for the corporate location.

I created a scope for the remote location (192.168.3.x) on my DHCP server and tried to configure the remote ASA DCHP Relay,

on the remote ASA: I disabled the DHCP Server on the inside. I enabled DHCP Relay on the inside, with set route set at yes.

I set the Global DHCP Relay Servers, specify up to four servers to which DHCP requests would be relayed. I added my DHCP, 192.168.1.254

I flashed these settings to the ASA and gave it a try, didn't do anything.

am i missing something - forgetting something. not really sure what im doing wrong.

DHCP Settings on remote ASA:

dhcp-client update dns server both

dhcpd dns 192.168.1.254

dhcpd ping_timeout 750

dhcpd domain JEWELS.LOCAL

dhcpd auto_config outside

dhcpd update dns both

!

dhcpd address 192.168.3.2-192.168.3.33 inside

!

dhcprelay server 192.168.1.254 outside

dhcprelay enable inside

dhcprelay setroute inside

dhcprelay timeout 120

On main ASA:

I have two ACLs to permit flow from the remote locations static ip for inbound UDP port 67 and 68 connections

dhcp cisco-asa

    You need to create a scope in the same subnet as each remote location. so at site 192.168.3.x you need a scope that falls withing the 192.168.3.x subnet.

    EDIT:

    Is that a typo in your question (102.168.3.x)? What's the scope you set up?
