However, one small caveat this feature is not supported by Cisco TAC so if you put in a ticket about DHCP reservations and static ARP entries you won’t get too far. When the scope was configured with a single address and a static ARP entry, I connected a different PC and the ASA would not hand out that single IP address to a different host. The end device configured with the static entry got the IP address in the static ARP entry configuration. I tested this out with a scope handing out a single IP address and a scope handing out multiple addresses with the same result. Somehow when the static ARP entry is configured, the ASA apparently knows not to hand out the address to a different host. However setting up a static ARP entry provides a quick work around for this feature. We can only speculate as to why such a simple feature would be excluded. In this scenario I’m going to have two VLANs, one for my wired clients, and one for a ‘Guest WiFi’ that I’m. If you use a platform such as an ASA 5505, which uses VLANs instead of a physical interface, you need to change the interface types as appropriate.

This way you can set multiple VLANs to use this interface as a gateway at the same time whilst still separating the traffic. This document was written with an Adaptive Security Appliance (ASA) 5510 firewall than runs ASA code version 9.1(1), but this can easily apply to any other ASA firewall platform. One of those of features is the ability to setup a DHCP reservation, the 5505 can run a DHCP server with various scope options but the ability to setup reservations has been left out. You can take the physical interface of a Cisco ASA firewall, (or an ether channel) and split it down into further sub-interfaces. It’s even cheaper than most of the current 800 series routers, can provide IPSec VPN access, An圜onnect access, and basic routing sounds like a great deal right? Well, it is however after a while you will notice some functionality is missing from this nice ASA that we take for granted in our normal everyday ISR Routers. So the Cisco ASA 5505 is the smallest ASA firewall in the ASA family, only designed for SOHO and real small branch office.
