Cannot ping from Internet

When I try ping router from Internet, I have no reply at all, I removed all deny rules in all firewall and I have only masquerade NAT rule on ADSL interface. I’m using MikroTik v2.9.6
I can connect to router with telnet without problems, but I cannot get ICMP echo-reply packets. From Lan, ping working normaly.

What can I do to ping working normaly from Internet ?

Just a thought: IS your adsl modem firewalled in any way ?

does your adsl require pppoe? if so is mikrotik doing the pppoe login ? or the adsl modem

Maybe your provider stops ISMP stuff from outbounded addresses.
