Route traffic to specific network through specific interface

I have a Ubuntu server hosted on Digital Ocean and used as a VPN and through it I would like to access my other servers there over the local network (Private Network). But I am unable to access other servers from my PC over the VPN (Request timed out on 10.8.0.1 = VPN server).

Route table on the VPN server:



default _gateway 0.0.0.0 UG 0 0 0 ens3
10.8.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0
10.19.0.0 0.0.0.0 255.255.0.0 U 0 0 0 ens3
10.19.0.0 10.19.0.1 255.255.0.0 UG 0 0 0 ens3
10.135.0.0 0.0.0.0 255.255.0.0 U 0 0 0 ens4
10.135.0.0 10.135.0.1 255.255.0.0 UG 0 0 0 ens4
7.7.7.0 0.0.0.0 255.255.240.0 U 0 0 0 ens3


tun0 is VPN network

ens3 is to the internet

ens4 is LAN
/Public net masked as 7.7.7.0/



So I would like to route all traffic going from 10.8.0.0/24 to 10.135.0.0/16 over ens4 (10.135.4.48) and all other traffic through ens3.



Do I have to change routing on my local machine?
