we use a fiber connection in germany, the provider (wemagcom) gives an IPv6/64 Prefix via DHCPv6-PD and IPv4 via CGNAT/Dual-Stack Lite (DSLite) - RFC2473.
Mikrotik becomes an IPv6/64 Prefix via DHCPv6-PD. Thats okay.
IPv4 works over in 4in6 Tunnel (DS-Lite) ... the provider sends the FQDN Hostname of AFTR Gateway (CGNAT) via DHCPv6 Option 64 (OPTION_AFTR_NAME, RFC 6334) ...
in our case is the hostname "aftr.aftr.local" and this resolve to an ipv6 Adress (2a03:b580:b000:1::1) of the AFTR Gateway-Server.
I want to send all ipv4 traffic in ipv6 tunnel to AFTR Gateway via Interface/IPIP6 Tunnel.... the local IPv6 is one local IPV6 Adress of WAN interface and remote IPV6 Adress is the adress from AFTR gateway.
When i create a route under IP->Routes for 0.0.0.0/0 to interface ipip6-tunnel1 (tunnel name) then the gateway is unreachable. When i look under IPv6 -> firewall -> Connections a connection to AFTR is listed... but the status is : unreplied.
I think that is the problem... when the status were not unreplied, then will the route works i think....
under linux works it with follow commands:
Code: Select all
ip tunnel add dslite1 mode ip4ip6 local [local ipv6-adress] remote [gateway aftr ipv6 adress]
ip l set dslite1 up
ip a add 192.0.0.1 dev dslite1
route add default gw 192.0.0.1
Code: Select all
configure
set interfaces ipv6-tunnel v6tun0 encapsulation ipip6
set interfaces ipv6-tunnel v6tun0 local-ip <<LOCAL IPv6 ADDRESS>>
set interfaces ipv6-tunnel v6tun0 remote-ip <<AFTR ADDRESS>>
set interfaces ipv6-tunnel v6tun0 mtu 1460
set protocols static interface-route 0.0.0.0/0 next-hop-interface v6tun0
