Got a question after reading the Lede online help for IPv6 IPv4 transition protocols.
- Archer C7 V2 with Lede optimized
- wtnet ds-lite connect
config 'interface' 'wan6'
option 'ifname' 'eth1'
option 'proto' 'dhcpv6'
config 'interface' 'wan'
option 'proto' 'dslite'
option 'peeraddr' '2001:db80::1' # Your ISP's DS-Lite AFTR
Using that setup the router only have a DNS for IPv6 and none for IPv4, means that all DNS requests for IPv4 fail. The Pro for such setup is, that i have only one NAT at the carrier's AFTR, against a double NAT cascade when using dhcp on both interfaces.
Why is there a general suggestion to not set a nameserver for IPv4?
