I'm already using 2 OpenWrt routers and want to buy a third one, to create a DMZ to isolate my LAN from my webservers. But if the servers are in the DMZ on the WAN side of the router and my other computers on the LAN side, I need a really good NAT throughput so streaming and file transfers keep at Gbit speed.
I looked through some routers and often it is said, that OpenWRT isn't able to use the hardware NAT of the router so thoughput goes down to 450Mbit/s for example.
Is there a router able to use hardware NAT with OpenWRT? Any recommendations?
And did someone already benchmarked the NAT throughput of the TL-WDR4300?
