L2TP + ipsec - no ping to /23 LAN

hi, i have fresh 6.34 mikrotik

configured internet, l2tp, ipsec… all working, except one. how to ping all /23 network ? for ex. 192.168.4/23

if i got ip from pool 192.168.4.* - i can ping only 192.168.4.*
if i got ip from pool 192.168.5.* - i can ping only 192.168.5.*

but i need to ping all network..


it works, i dont know why, but works, all i do is put dns and domain to dhcp server config
