Hello all, I am trying to setup dhcprelay on an ASA 5505, but I'm having an issue enabling the feature. I removed the default dhcp server & range off the config and issue the following commands:
dhcprelay server 192.168.1.100 LAN
dhcprelay setroute LAN
dhcprelay enable LAN
DHCP: There is a DHCP Server '192.168.1.100' configured on interface 'LAN'!
DHCP Relay cannot receive DHCP requests and forward them on the same interface.
However, as you can see, I get an error when I try to enable dhcprelay on the LAN (inside) port. I am using a Windows 2008 Server as my DHCP server (will be plugged in to port 0/2). I have an ASA 5505 with the basic licensing package. Any help is greatly appreciated!
Here's my current config:
