ASA 5505 Restore to Duplicate Unit.

I have a Cisco ASA 5505 with Security Plus license configured for WAN, LAN and DMZ, which has been working great for several years. I just purchased a new ASA 5505 with SP on Ebay (Yes, I know I probably should have purchased it through a Cisco partner) as strictly a backup unit to swap out if the original dies or if I need to bring it down for upgrades or repairs. However I cannot get the backup to work.

This is what I have done in an attempt to duplicate the new ASA 5505 device as a backup:

Using the console, I saved the running config from my working 5505 to my tftp server, and then copied the running config from my tftp server to my new 5505 as startup config. After issuing the reload command, the unit booted up properly with a running config identical to my working 5505. However if I swap out the devices, I cannot get to the WAN or DMZ through the backup device.

Both units are running ASA 8.2(1) with ASDM 6.2(1).  The units are identical except for the fact that the working unit has 1GB of RAM and the backup has 256MB. I printed out the running config from both units and compared them line by line, and they are also identical except the backup unit has 1 added line: anyconnect-essentials.

I am not an ASA expert by any means, and am wondering if I missed something, or should it work based on the steps I took?

Turns out it was the ARP table in the modem/router. After rebooting the modem, everything works as it should.  I have to give jcarvaja over at the Cisco firwall forum credit for this fix as he pointed me in this direction.
