I had to play with Dual WAN recently because my WAN port started negotiating at 100Mbit. So I used dual wan mode to make the 2.5Gb LAN port as the primary WAN. As I remember it, it required that I still keep the WAN port as alternate, so I couldn’t repurpose the WAN port to LAN (I wanted to perform more cable tests).For those of you that have this router is it possible to set it up using one of the 4, 1g LAN ports as primary WAN? I don't have dual WAN to make use of that and not sure if that's something you can configure.
The reason I ask is I only need 1G for WAN but have a use for both 2.5G ports in the LAN as both my main pc and NAS have a 2.5g capable port and the enhanced copy speeds for backups SSD to SSD would be great.
I could be mistaken, but that’s how I remember playing with it on the stock firmware. The router is shipped off to Asus now, so I cant confirm my own B.S.
