Help with multiple wan configuration

[scatt]

Hi there,
i'm running pfsense for a while to use load balancing with my 2 wan, but now i have a bit of trouble.

Since a couple of days the setup was:
Wan1(78.26.x.x)
Wan2(192.168.2.1/24)
Lan(192.168.1.1/24)
Every was working for wan1, some little trouble with FTP and other with wan2 but normal web surfing was acceptable.

Now i have changed the setup as follow:
Wan1(78.26.x.x)
Wan2(172.16.1.1/24)
Lan(192.168.1.1/16)
as before Wan1 is correcly working, no problem at all, but on the other wan i continue having blocked traffic,```
Default deny rule IPv4 (@4)   172.16.1.2:64138   216.58.205.101:443

On wan1 i have multiple static ip adresses and since i use only 1 i have used one of the other for the wan1 interface on firewall, but on the other interface i don't have other ips, i'm quite sure that the wan2 setup is not ideal, can someone help me to solve this issue?

based on my research i have figured out that should be a double nat problem, i will open a post on the NAT section
