VPN blocked?

RouterOS General
1

I am getting error when I try to connect to SMB server through VPN; my mac says server doesn’t exist or is unavailable, and wyhen I try to ping IP in local lan I get:

36 bytes from 188.252.172.1: Communication prohibited by filter
Vr HL TOS  Len   ID Flg  off TTL Pro  cks      Src      Dst
 4  5  00 5400 bcff   0 0000  3e  01 98ec IP IP

Can someone please point me where to look? I have had this working before.

Router is RB3011.

You should check firewall rules on 188.252.172.1.

Heh.. I am not sure I have anything with that one. It is not my router, just checked the public IP??
Might be ISP? But the rule does look like a problem with something blocking.

Any way I could probe this somehow?
