i have this configuration:

I have config Network on VPN cloud 192.168.1.0/24 and download config and upload on client network on NAS synology.
Synology connect to vpn correctly.
Network Synology is : 192.168.1.106/24 - gw= 192.168.1.254
Pc2= 192.168.29.1 (192.168.29.0/24)
Pc1= 192.168.1.100 (on same network synology - 192.168.1.0/24)
and when i connect to vpn from pc2 on rete2 with network 192.168.29.0/24 -> connect to vpncloud with vpnconnect3
i connect ok
if i ping nas is correct.
The route is correct becouse there is a route that download in automatic from vpn 192.168.1.0 -> to vpn
So when i ping from 192.168.29.1 (pc on rete2) -> to Nas (192.168.1.106) = ping is ok
Now if i want ping another PC1 on rete1 (192.168.1.0) the routing is correct but i think that less another route i think on the pctest2.
becouse from PC1 if i do tracert -> 192.168.1.100 the trace go to vpn but there isn't response after.
So What route i must add for ping PC1 from pc2 ?
Or what is wrong?
Thanks for help.
