That's an excellent start.  I would add

* availability of global IP addresses (0-n)
* ability to connect to "unusual" ports (falls under "filtering")
* ability to accept connections
* interception of common TCP ports such as 80 and 25
* transparency for various header fields (addresses & ports=C2=B8 DSCP...)
* rate-limits for specific protocols (ICMP, BitTorrent...)
* latency and throughput for some popular sites/resources, including
  those using CDNs, at various times of day/week
...and of course...
* availability of IPv6
