VPN not working after migration to Mikrotik

RouterOS Beginner Basics
1

Hi ,

we just bought mikrotik (RouterBOARD 3011UiAS) to our LAB env, but we have problem with PPTP VPN, clients in network cannot connect to external PPTP server (not mikrotik) error 619

on the old router Linksys everything works fine,and with different router it is working without problem, so problem is in mikrotik.

Service ports for pptp is enabled
/ ip firewall service-port enable pptp

no firewall rules

NAT rules

0 ;;; Masquerade Public Traffic
chain=srcnat action=masquerade src-address=10.10.10.0/24
out-interface=WAN1-ether1 log=no log-prefix=“”


client pc —> Mikrotik —> ISP ----> pptp server not working
client pc —> linksys ----> ISP ----> pptp server working


and we cannot change PPTP server, so try different VPN is not an solution :confused:

can anybody help me here ?

Thank you

Enable debug logs. It will give you more information to help you troubleshoot your connection.

/system logging add topics=pptp,debug,!packet

PPTP VPN uses TCP port 1723 and GRE (47) protocol. You need try to enable service-port GRE, if it not works, you must create firewall rules to accept or passthrough for GRE protocol and TCP port 1723
