Cant get Comcast IPv6 to work through Zyxel WyWALL 110 Firewall

I am trying to enable IPV6 through my ZyWall 110 with my ISP (comcast). If I connect directly to the comcast router the IPV6 works, however, through the firewall it doesn't work.

Here is the dedicated information I have been provided by Comcast:
Static IPv6 Information: 2603:3001:390b:6d00::/56
Static IP Range: 96.93.179.209 - 96.93.179.221
CIDR Block Number: 96.93.179.208/28
Gateway IP Address: 96.93.179.222
Subnet Mask IP Address: 255.255.255.240

I followed the instructions located here, but to no avail:

and tried http://forums.xfinity.com/t5/Your-Home-Network/ZyXel-USG50-IPV6/td-p/1997983

 

You can see the wan configuration here:

You can see the lan configuration here:

When ssh'd into the router this is what I see:

Then I ping google and it works:
Router> ping6 ipv6.google.com
PING ipv6.google.com(2607:f8b0:4002:802::200e) 56 data bytes
64 bytes from 2607:f8b0:4002:802::200e: icmp_seq=1 ttl=55 time=49.0 ms
64 bytes from 2607:f8b0:4002:802::200e: icmp_seq=2 ttl=55 time=28.7 ms
64 bytes from 2607:f8b0:4002:802::200e: icmp_seq=3 ttl=55 time=27.0 ms

--- ipv6.google.com ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2002ms
rtt min/avg/max/mdev = 27.082/34.962/49.024/9.967 ms

 

Then I connect my pc to the LAN port (ie DPFW1) and here is my setup:

And here is my routing table:

But when I test pinging google, it does not work. I can ping the LAN (DPFW1 Interface) but not WAN (xfinity) interface:

Hello digitalpioneers and welcome to forums,

 

I apologize for the delayed response to your post. Unfortunately I cannot speak to proper configuration on your 3rd party network equipment. I did want to confirm with you that you only have one device pushing IP delegation i.e. disable DHCP in our gateway or on your network device. This may be one configuration step closer to getting you IPv6 routing properly. Please let me know if your gateway has any issues with your connection.

 

Thank You
