Re: What firewall are you using that is capable of 50 Mbps?
With my own testing, I've found that my Netgear WNDR-3700 v2 router tops out at about 150 Mbps when running DD-WRT, and 500-550 Mbps when running stock firmware (I think it might be OpenWRT based). SPI firewall, NAT, and port forwarding are all in use. -- KI6RIT
