Hi, i have a strange problem with pptp server.On some routers it works but on some its not working. Today i set up pptp server on mikrotik, just enabled pptp-server, in secrets i added user, pptp client connects but i cannot ping computers in network. Here is configuration od mikrotik, i dont know what i miss.

[admin@MikroTik] > ip address print 
Flags: X - disabled, I - invalid, D - dynamic 
 #   ADDRESS            NETWORK         BROADCAST       INTERFACE  
 0              ****                                                              WAN
 1   192.168.1.37/24    192.168.1.0     192.168.1.255   LAN




[admin@MikroTik] > ip firewall nat print 
Flags: X - disabled, I - invalid, D - dynamic 
 0   chain=srcnat out-interface=WAN src-address=192.168.1.0/24 
     action=masquerade 

 1   chain=srcnat out-interface=WAN src-address=10.0.0.0/24 action=masquerade 

 2   chain=srcnat out-interface=WAN src-address=10.45.0.0/24 action=masquerade

You need to change ARP on the LAN interface to proxy-arp.

I already done that but no results.
