MikroTik Port Fowarding


MikroTik Port Fowarding
Port Fowarding is one of the features of the mikrotik router (RB450g, RB750g, RB1100Ahx and other mikrotik router series). Port Fowarding on mikrotik router is used to redirects from destination address (external ip address/ ip WAN Public) to source address ( internal ip address / IP LAN) based on port number. This technique is most often used to make a host (such us web server, ftp server, ssh server, personal pc and other network devices)  that is on the internal network can be accessed via the external network (the Internet) and protected without going through a dial-up VPN or other type of vpn.

Configure Port Fowarding on Web Server
Standart ports web server is TCP 80 (http) and 443 (https). Many network devices can be accessed via web based by using port TCP 80 and other port, for example cctv, ip camera, dvr, and other. This example will show you how to foward port web server (tcp 9000) to destination NAT.

Fowarding Port using Winbox
Login to Mikrotik Router Using Winbox Application
Go to IP
Firewall
NAT
Click on General Tab
Chain = dstnat Dst
Address = WAN IP Address Mikrotik Router Protocol = TCP
Dst Port = 90005-22-2015 2-49-43 PM

Click on Tab Action
Action = dst-nat
To Address = Internal Destination IP Address (Web Server IP Address)
To Port = default port (Port 80)5-22-2015 2-51-00 PM

Mikrotik Port Fowarding FTP Server, SSH Server, Mail Server, RDP (Remote Desktop Protocol)
FTP Server = 20 & 21 TCP
SSH Server = 22
Mail Server = POP3 – port 110, IMAP – port 143, SMTP – port 25, HTTP – port 80, Secure SMTP (SSMTP) – port 465, Secure IMAP (IMAP4-SSL) – port 585, IMAP4 over SSL (IMAPS) – port 993, Secure POP3 (SSL-POP) – port 995
RDP (Remote Desktop) = TCP port 3389 and UDP port 3389
RSTP (Real Time Streaming Protocol) = TCP port 554, UDP Port 3389

Enter Default Port of Network Protocol that will be Forwarded5-22-2015 3-59-06 PM
