VPN Ping is working only with gateway

Hello guys
I set up PPTP VPN connection. My clients can connect to VPN, but something strange i happenig. When I am trying to ping anything, I have only access to gateway (192.168.88.1). I can’t access anything else from my network.
Here are some screens with my configuration:

So your gateway is 192.168.88.1, correct?
What range is the VPN IP pool in?
If it is in the 192.168.88.0/24 range as well, you’ll either have to set your local bridge to proxy-arp or (even better) give your VPN pool a seperate IP range (like 192.168.90.0/24).

Write ip pool?
And should add your pool in firewall nat and action masquerade.
And in pptp server don’t select “chap, pap” select only mschap1 mschap2.

This is my setup for L2TP VPN, maybe you’ll find something that will help, I don’t mess with PPTP.
