Allow LAN1 to access devices on LAN2

[derril]

My LAN1 network 192.168.1.1 and LAN2 is 192.168.18.1
I have an AP and a server running in LAN2 i would like to access from LAN1.
I see a lot of results for this but people usually need blocking or specific ip accessing specific ip.
I have named LAN2 network AP. I tried to add rule in LAN1 but i keep messing because i don't know if i need to use LAN net LAN address etc same for AP net AP address...
I am the sole user of this network so i would like all these devices to be able to communicate between them, maybe even make a network dir on the server to share with the TV etc.

There is a default LAN IN rule that should have allowed to get from LAN1 to LAN2 but if it's not there for some reason, you can simply create it to achieve your goal.
Firewall > rules > LAN1:
Action: pass
Interface: LAN1
Direction: in
Source: LAN1 net
Destination: LAN2 net #for allowing only going across from LAN1 to LAN2
Destination: Any # this is the LAN default which means allow all traffic into the interface, regardless of destination. This is a rule that should have been created by default but please check if already exists, it should just work.

Leave all other fields with default values, except "Quick". as you might want to see if this is what you want.
