Static routing question

[Nisha555]

Hello,

I have 2 pfsense machines and 2 esxi servers.
Each pfsense has 3 VLAN's and on each esxi server is a machine connected to a vlan and they succesfully get a ip from the dhcp server on pfsense.

On side 1 the ip ranges are:

VLAN 10 : 172.16.16.1/20     
VLAN 1  : 192.168.2.254/24 
VLAN 25 : 10.0.0.30/28

Side 2:

VLAN 10 : 172.16.0.1       
VLAN 1  : 192.168.0.254   
VLAN 25 : 10.0.0.14/28

For now there is a ethernet cable between the 2 for testing which will be replaced by a wifi bridge.
Because of that ethernet cable they both get dual WAN
Which static routes should I add so the machines on the VLAN's can ping the machine on the other side of that VLAN?

Thanks in advance.
