PPPwn over 2 routers.

[aasd6574]

I have an openwrt router in my room, and want to jailbreak my ps4 in the livingroom.
Openwrt IP address : 192.168.2.0/24
ISP modem Local IP address: 192.168.1.0/24
I have the local networks route together, so it can ping each other, works fine with any other device (SMB share, ssh, etc.)

The openwrt router start the payload, it goes this and get stuck.

The payload goes from the second router (Openwrt) 192.168.2.1 -> wan port -> First router (ISP modem LAN port) 192.168.1.100 -> ISP Other lan port -> PS4.
So it can communicate.
But gets stuck... any idea how to fix it, maybe firewall on the ISP modem for getting the packets back or any other settings?
Any of you got the same issue from getting the payload through 2 router/network?

Forgot to mention, it works when the openwrt router is directly connected to my ps4.. but I don't want to disconnect it from my room and power on it in my livingroom.
