We have 2pfsense PC's and each one has its own WAN.
Static routing is engaged, how can I enable access to wan1 on pfsense1 for someone on pfsense2?
Becouse it's forcing him to wan2, and I wan't him to redirect to wan1.

Maybe I dont understand your diagram, but you might want to try policy based routing.i.e.:

If you want to route traffic for 200.20.20.0/24 from the RED firewalls LAN to WAN1 on the YELLOW firewall. Make the first LAN firewall rule
source    destination            gateway
*            200.20.20.0/24      OPT    (assuming OPT is the interface connected to YELLOW)

Then on YELLOW you need to allow the from RED traffic through.

So, RED needs to get out on WAN1. How?  ???

Thanks for any help, I'm kind a newb in all this.

Routes on yellow:
BBPOJWIR2  10.111.2.0/24  10.111.12.2       
BBPOJWIR2 10.111.20.0/24 10.111.12.2

Routes on red:
BBPOJWIR2  10.111.0.0/24  10.111.12.1       
BBPOJWIR2 10.111.1.0/24 10.111.12.1

And all the people from 10.111.2.x have the same IP adress 10.111.12.2 on our local IRC. Why is that?

Becouse it's forcing him to wan2, and I wan't him to redirect to wan1.

I'm not sure if i got you right… I assume your LANs NATed?
If so, the easiest way would be to allow WAN2-IP on WAN1 incoming:

Proto  	Source   Port   Destination  	    Port     Gateway  	Description  	
TCP 	WAN2 	* 	WAN1 address 	443 (HTTPS) 	*        pfsense2 -> pfsense1 

So, anyone from LAN2 would be able to connect to WAN1. As you password-protected your GUI on WAN1, that is no big risc at all.
