8. Routing Performance

Routing performance was a case of uncovering something both fantastic and terrible. Connecting LAN to WAN, I was able to consistently achieve a truly fantastic transfer rate of 88.5 Mbps! Considering the overhead that a TCP connection naturally has, this is an amazing number.

On the flip side, I was completely unable to get UDP streaming numbers after spending many fruitless hours checking and rechecking configuration settings, including completely disabling the firewall's SPI features and putting the LAN machine in DMZ.

I was able to send UDP packets from the LAN to the WAN but the streaming test would not complete due to the inability of Qcheck to return its results from the remote endpoint. Going from WAN to LAN was even worse, since no communications would connect inbound when using a static WAN IP.

The UDP problems are common when using Qcheck to test routers with SPI + NAT firewalls, since Qcheck isn't designed to handle this newer, but now common firewall. But the complete inability to run any WAN-LAN tests is a new behavior and I wasn't able to resolve the cause of it with SMC.
