The N300 doesn't perform SPI
Just for information… ;)
I would be very surprised if that was true. The Netgear is probably running am embedded Linux of some description and using IP tables. That is a stateful firewall. Though you haven't said exactly which model so I suppose it might be possible.
It's the DGN2200v3 N300 Modem Router and states it has IDS and DoS protection. The N600 Modem Router specifies it does SPI and DoS protection. I believe it is running a Linux distro but with the exception of when I ran the Shields-Up scan against it at grc.com, which it classified as a null scan, everything else it logged for the 4 days I ran it before bridging was classified as a DoS attack: ACK Scan.

I have serious doubts it was logging everything it blocked due to the large number of varied log entries I had with pfSense within an hour of setting it to do the firewall duties. It may well be doing SPI, and I run the pf firewall on my computers so I wasn't worried, but it didn't instill any confidence in me for it as far is it being a firewall beyond doing NAT.
