I am trying to get dhcp snooping to work with option 82 turned on. from my understanding, to use ip source-gaurd for non-ip traffic, this "requires" the use of option 82, so I am trying not to disable option 82 on the switch. If I have a router acting as a dhcp relay and/or dhcp server, I can configure the router to accept option 82 packets from the switch. This is done with the following command: interface fa0/1 (interface facing the dhcp client) ip dhcp relay information trusted now this lets the router accept dhcp requests with the option 82 set from the switch and everything works great. Now here is where I am running into trouble. If I configure an asa as a dhcp relay or dhcp server instead, the firewall ignores the dhcp requests with option 82 set from the switch. Is there a way to allow the dhcp request to be accepted (in exactly the same way as the ios router)?
