I have a RB5009UG+S+IN router currently set up with IPv4 and Comcast. Everything with IPv4 works perfectly and I’m trying to set up IPv6 with the unit. It seems that I can’t get the Mikrotik router to pull an IPv6 prefix. Ether1 is the interface connected to the Comcast cable modem. This is the IPv6 config on the router:
/ipv6 dhcp-client print detail
Flags: D - dynamic; X - disabled, I - invalid
0 interface=ether1 status=searching… duid=“0x00030001789a18f73bf9” dhcp-server-v6=:: request=prefix
add-default-route=no use-peer-dns=yes dhcp-options=“” pool-name=“pool_ipv6” pool-prefix-length=64
prefix-hint=::/0 dhcp-options=“”
/ipv6 dhcp-client print
Columns: INTERFACE, STATUS, REQUEST
INTERFACE STATUS REQUEST
0 ether1 searching… prefix
It never seems to get past the “Status: searching…” and never gets any IPv6 info from Comcast. I have directly connected a spare laptop to the Comcast modem and it successfully pulls an IPv6 address and I can go to an IPv6 test website and it passes. Also I have an Asus router that supports IPv6 and I’ve tested that on the same Comcast line and it also passes the IPv6 test 100%. Do I need to reconfigure something on the firewall on the Mikrotik to allow it to receive an IPv6 prefix from Comcast? Thank you.
