Generic questions for all dual WAN routers:
1-When you have a dual WAN situation configured, and both WANs are configured for 'use DNS from ISP', and each WAN ISP gives the router two DNS servers, which DNS servers do the LAN network clients get from the router and how do the clients determine which DNS servers to use?
2-Network interruption detection. I see various metrics used to flag a failover situation, yet I can't see if this failover is specific to IPv4. Do any of these dual wan routers failover ipv4 and ipv6 separately, such that ipv6 can be in a failover state in wan1 (ipv6 packets then directed to wan2) all while ipv4 continues to work fine on wan1?
