vpn routing

Hello,
please help me with routing tp vpn network issues.
I can't ping host in vpn network from lan (192.168.100.0/24).
But when I try directly from mikrotik through vpnclient interface it works.

My configuration:
RouterOS 5.20


/interface print

NAME TYPE MTU L2MTU MAX-L2MTU

0 R KAB ether 1500 1600 9116
1 R LAN ether 1500 1600 9500
2 R NEO ether 1500 1600 9500
3 R vpnclient pptp-out 1460

LAN - local network
KAB, NEO - ISP network
vpnclient - vpn network

/ip address print

/ip firewall nat print

I have two ISP with PPC load balancing
