After setting up my Cisco ASA5505 to perform NAT (Network Address Translation) I wasn’t able to access the server from outside the firewall.

I tested this on a few different 8.4 versions with success but since it isn’t a supported feature I wouldn’t really rely on this for anything mission critical but it something to keep in mind if you are in a pinch. If you haven’t done this yet or lack faith in your NAT setup, I have also posted instructions on how to set up a NAT on the Cisco ASA 5505. 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. For those of you searching the Internet to try and find a good or simple example of how port forwarding is done on a Cisco ASA 5500 series firewall (in this example, it is a Cisco ASA 5505 version.

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. It delivers high-performance firewall, SSL and IPsec VPN, and rich networking services in a modular, immediately operational appliance. However setting up a static ARP entry provides a quick work around for this feature. The Cisco ASA 5505 is a full-featured firewall for small business, branch, and enterprise teleworker environments. We can only speculate as to why such a simple feature would be excluded. 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. will this cause any slowness in the firewall asa 5505 and will this block the ddos for good or just hang when the ddos tries to reach the network user3376096. 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 will a cisco asa 5505 or even 5520 hold in that or will it slow things down/hang etc.

So the Cisco ASA 5505 is the smallest ASA firewall in the ASA family, only designed for SOHO and real small branch office.
