PPPoE server

Hello,
I have a problem:
Mikrotik 2.9.27 set-up as pppoe server
Clients (winxp) can connect succesfuly to pppoe server and access internet

How to put a route to access from PC0, PC1, PC2 >> the PC3
Every client can ping 192.168.0.1 but can`t ping the PC3 (192.168.0.4)

10x in advance

Hi,

in winXP, when you create your VPN, you have to disable one option.
Is like in VPN connection properties, LAN functions, TCP/IP, properties, advanced options, use predeterminated gateway in remote connection.

no, not work these setings.
any else?

Check the firewall for icmp
