Secondary IP On Cisco ASA
While decommissioning some old routers, I need to transfer an IP address to an ASA on a subnet. Unfortunately the ASA’s don’t allow you to do this. The standard “ip address X.X.X.X Y.Y.Y.Y secondary” doesn’t work. I did a quick google and this beautiful bastard had the solution, static ARP with proxy-arp. Figure out what…

It seems that as of version 8.3 of the ASA code, you have to have 2GB of RAM in your 5520 and 5540, a meager 1GB is necessary for your 5510. The funny thing is that prior to February, all of these devices shipped with only 512MB of memory…that’s a pretty significant jump, wouldn’t you…

I noticed that the ASA said that the connection was using NAT traversal,…

Cisco ASA IP SLA – Failover Routing
It seems like everytime I want to do something funky with an ASA, Cisco says “ASAs are not routers, use them what they are designed for.” This really doesn’t help me…heh. ASAs can’t do PBR(Policy Based Routing – aka route maps)…which would have been useful more than a few times. Back on topic, failover routing.…
