Wireguard - Unable to pass traffic between instances

[xnadmin1337]

Been searching for a while, can't really find anyone with a similar problem.
I've got 2 wireguard interfaces, wg1 and wg2. wg1 hosts remote access peers like phones and laptops, wg2 hosts site to site connections. I've established a connection on wg2 and it can pass traffic from one LAN to the other LAN, at least from the firewall. However, clients on either LAN can't access the other side, as well as remote access clients being unable to access the remote LAN.

I've tried every firewall rule I can think of but nothing works, the firewall log does show traffic being passed in some cases but ping tests always timeout. I'm at a loss trying to figure out how to make this setup work.
