I have just installed LEDE latest version on my WNDR3700. I have connected the WAN interface to a Fibre (FTTP) router that is in bridge mode. LEDE is awesome! I have mwan3 running as well to failover to my secondary line - works a treat!
WAN interface has PPOE enabled with my providers credentials entered.
Question - should I be using WAN or WAN6, and what is the difference? Both interfaces appear to work and both get ipv4 and ipv6 addresses. In fact if i enable both together i get two seperate ipv4 addresses, one on each interface
My ipv6 address is a /128
Possibly related question question is why I only seem to get 1/2 bandwidth on any one connection. My connection is 30Mb/s but each download gets max 15Mb/s. I can however run two downloads and get the full 30Mb/s.
