I had IPv6 working for quite awhile, but it stopped working recently. Of course, I can set up an HE tunnel on my router, but I thought I'd troubleshoot things a bit more.
My router: E4200 with Shibby's Tomato Firmware 1.28.0000 MIPSR2-109 K26 USB AIO.
Scripts I'm using:
Firewall (I don't know the escape characters here; backslash is an actual backslash): ip6tables -t mangle -I OUTPUT 1 -o 'nvram get wan_iface' -p icmpv6 backslash! --icmpv6-type echo-request -j RETURN
WAN Up: route -A inet6 del default gw :: metric 1024 'nvram get wan_iface'
I'm using DHCPV6 with prefix delegation /64
Accept RA from WAN is enabled; respond to ICMP is also enabled.
My router gets an IPv6 address 2601:* etc... Link local address is fe80::* etc...
From my SB6120 logs: CMTS-MAC=00:01:5c:3f:3a:4e which shows as a Cadant.
Model Name: SB6120
Vendor Name: Motorola
Firmware Name: SB_KOMODO-1.0.6.10-SCM00-NOSH
Boot Version: PSPU-Boot 1.0.0.4m1
Hardware Version: 1.0
Firmware Build Time: Oct 29 2012 18:07:13
Looking over previous threads, my only clue is that it could possibly be an issue similar to this one:

Any thoughts? I can provide more info if necessary.
