When I set IPv4 and IPv6 addresses at the same time on the LAN and WAN interfaces, the system can automatically generate IPv4 outbound rules, but cannot generate IPv6 outbound rules. I need to add these Outbound rules for IPv6 manually.
Hey,
do you mean "automatic outbound rules" in Firewall/NAT settings?
You should know that IPv6 does not require NATing, so you don't need any automatic rules.

Yes，But I just want to use IPv6 NAT like in IPv4.Because IPS cannot provide dynamic IPv6 address correctly by dhcpv6 or SLAAC.
Ok, this is not recommended and a bad idea. You should really have a good reason. You can configure IPv6 NAT rules by yourself. This will not happen automatically.
I've tested it here and configured a manual rule. Its working. So if you really want to do this, what exactly doesn't work on your setup?

Be careful! I didn't mean that adding manually not work. I just want automatic generation should be supported like IPv4. Although IPv6 is enough, it does not mean that NATv6 technology is obsolete.
No, it should not. IPv6 was explicitly designed to eliminate NAT.
I might add that even manual outbound didn't work for me with dynamic public ipv6 addresses. After a few changes it stopped switching the outbound NAT IP.
