Block VPN access using Mikrotik. To get to the configuration stage we must first understand how VPN (Virtual Private Network) works. Usually people use VPN access to be able to access the sites that we have filtered.
To avoid internet access used for negative things as network admins sometimes we need to do some filtering access. Here’s how to block VPN access using Mikrotik.
Among the several VPN protocols that exist, the most widely used are PPTP and L2TP/IPSec. Each VPN protocol has its own port, from that port we can already start the configuration on Mikrotik. Here the VPN port data is PPTP and L2TP/IPSec.
Point to Point Tunneling Protocol ( PPTP )
- TCP/1723 : digunakan oleh pptp control path.
- GRE : digunakan oleh pptp data path.
Layer Two Tunneling Protocol over Internet Protocol Security (L2TP/IPSec)
- UDP/500: Used by IKEv1/IKEv2 IPSec control path.
- UDP/4500: Used by IKEv1/IKEv2 IPSec control path.
- UDP/1701: Used by L2TP Control.
