Hi,
I am using mikrotik as an hotspot/pppoe server, the problem i am facing currently is users are not able to connect to there office VPN. VPN gets stuck during authentication process of it. I have tried allowing 47/50/51/500/4500/1780/1723/49000 ports but no use still the issue persist.
Please help me out.

How have you done that? 47, 50, and 51 are IP protocols, not ports.
What kind of VPN are they using? IPSec? PPTP?
47 is gre /50-ipsec-esp/51-ipsec-ah
both are there
Double check in your filter rules that you have an allow entry for Related as we as Established connections.
I am using the following firewall rules http://wiki.mikrotik.com/wiki/Protecting_your_customers but with limited ports on block [25/135-139/445] . Yes i has a rule to to allow related and established connections.
Do you have pptp or ipsec enabled on the router itself? Perhaps data is getting caught by that instead of forwarded away properly.
Nope nothing…been enabled
