Going to get a small PIX for training/testing. Not interested in performance (throughput, users etc), DMZs or failover. Is there any other real advantage to go for a 506E over a 501? You can run the same OS on all PIX models can't you?
Then go for the 501. 506e only supports 2 interfaces, no failover, and no vlan support. If you need vlan/failover/ or a dmz testing environment, go for a 515 or a 520, otherwise, a 501 is fine, provided you can live with the 10 (or 50) user version
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
