l2tp help with accessing lan from hq to branch office

Hi guys,

This is my first time asking question on this particular VPN topic. Currently, the HQ lan ip is 192.168.0.0/24, while branch office lan ip is 192.168.2.0/24.
I’ve setup the L2TP with IPSec VPN, so there is no problem where branch office PCs can access to HQ lan. For the other way around, i can’t seem to access anything. I’ve added route as well…maybe someone can look into this matter?

My setup is as follows : -

HQ Static IP : - Acts as the VPN Server.
Branch Office on 4G LTE, uses the VPN to connect to the HQ, and traffic is route through there.

Thanks!
