How to connect second mikrotik router to intertet

Hello, I am new in mikrotik configuration and I want to see where is my mistake.
So the hardware configuration is: ISP → Router 1 → Router 2 Connected as follows
ISP in Eth1 on R1 IP adress by DHCP.
Eth4 on R1 connected to Eth1 on R2
Eth2 on R2 Connected to PC.
Configuration that i made is as follows:
R1
IP addres eth1 192.168.168.99.260/24
IP addres eth4 10.0.0.1

Ip routes
0.0.0.0\0 → 192.168.99.1
10.0.0.0/24 → 10.0.0.1
172.19.3.0/24 → 10.0.0.2
192.168.99.0/24 → 192.168.0.160

R2
IP addres eth1 10.0.0.1
IP addres eth2 172.19.3.1

Ip routes:
0.0.0.0\0 ->10.0.0.1
10.0.0.0/24 → 10.0.0.2
172.19.3.0/24 → 172.19.3.1
192.168.99.0/24 → 10.0.0.1

There is ping between both routers, from the R1 i can ping 192.168.99.1 (ISP gataway ) I can ping and 8.8.8.8

BUT
From R2 i can`t ping neither 192.168.99.1 neither 8.8.8.8
Please Help what can be the problem.

Best regards
