Haven't made any IPv6 rules yet. Figured the ANY ANY Default Network Policy would cover it.
Hi,
I think I see the issue, you are trying to use a bridge mode? Has your isp assigned you an address range for your internal network eg /56 or /48?
if not a bridge you need a different ipv6 /64 address range for your interfaces.

Port 1 & Port 4 are in a bridge mode with an IPv6 of fc00:2222:3333:4444:cccc:dddd:eeee:ffff/64
This is where the server we are trying to get to connect to the Internet via IPv6 is. What IPv6 should I use for the Port 1 & Port 4 bridge? We don't think our ISP isn't giving out IP's, but then we're not sure how the IPv6 on ABCDOM01 was obtained automatically and since it starts with the 2600: it would appear to be from our ISP Spectrum. By the way, now with the new automatically obtained IPv6 we are no longer able to get a reply from the internal WAN interface.
If we enter fe80::7e5a:1cff:fe82:7215%3 on Port 1 for the IPv6 is says invalid. Sorry, we just aren't well versed in IPv6 yet and don't know how to translate the %3.
