Static IPv6 Routing Blocked by Modem Firewall
My ipv6 is working fine over the default /64. I have the Cisco 3939 modem. I have a /56 static prefix delegated to the modem.
I'd like to statically route an additional /64 to my internal router.
I've set up my internal router to send a router advertisement for the prefix.
Once I enabled this, I now see the following in the firewall logs for the modem:
| FW.IPv6 INPUT drop, 2022 Attempts. | 2016/12/07 04:23:23 | Firewall Blocked |
| FW.IPv6 FORWARD drop, 241 Attempts. | 2016/12/07 02:31:38 | Firewall Blocked |
The IPv6 firewall on the modem already has "Disable entire firewall" checked.
My guess is that the firewall has a default ruleset to only allow the base /64 through and is dropping packets from the new /64.
Is there anything I can do to truly and completely disable the IPv6 firewall on the modem? It seems that this is the only thing in the way of my routing working.
Note that I am not trying to do prefix delegation. This is a static subnet route.
