Therefore, if you configure the control port to port 4131, the default data port is port 4130. Most FTP clients use passive mode FTP. This means that the client first connects to the FTP server by using the control port. Next, the FTP server assigns a high TCP port between ports 1025 and 5000. Then, the client opens a second connection to the FTP server for transferring data. You can configure. When you configure a L2TP/IPSec VPN on a MikroTik RouterOS device you need to add several IP Firewall (Filter) rules to allow clients to connect from outside the network.

How to block specific network protocols and ports by using IPSec Summary. Internet Protocol security (IPSec) filtering rules can be used to help protect Windows 2000-based, Windows XP-based, and Windows Server 2003-based computers from network-based attacks from threats such as viruses and worms. This article describes how to filter a particular protocol and port combination for both inbound. IPSEC has no ports. In IPv4 IPSEC, or to be more precise AH (authentication header) and ESP (encapsulation security payload), are two IP protocols just like TCP and UDP. In IPv6 IPSEC is part of the protocol are there are two extension headers one for authentication and one for encryption OVS IPsec Tutorial¶. This document provides a step-by-step guide for running IPsec tunnel in Open vSwitch. A more detailed description on OVS IPsec tunnel and its configuration modes can be found in Encrypt Open vSwitch Tunnels with IPsec Port forwarding on port 500 or 4500 will cause IPSec traffic to be misdirected and disrupt proper tunnel function; Additional Information.
