Traffic Shaping In PFsense




Traffic Shaping:

We can define traffic shaping by two ways.      1: By interface 2:By Single User 
Traffic shaping by interface: By Interface

Traffic shaping by single user: Limiter
We can control bandwidth usage per client with adding download and upload limit. For controlling bandwidth we need to follow these simple steps

1-      Select Limiter option under firewall tab.
2-      Hit on “+” sign create new limiter
3-      Fill some fields and enable this rule. Like as Click on enable switch then add name as Download or upload after that we need to add bandwidth in kb/s or Mb/s etc. we can add description here too.
4-      Save and apply changes

Layer 7 Rule: Layer 7 filtering or shaping is identifying traffic at layer 7 of the OSI model. Some time we cal layer 7 as Deep Packet Inspection (DPI).
In TCP/IP, the application layer contains the communications protocols and interface methods used in peer-to-peer communications across an Internet Protocol computer network.
So let see the settings in PFSense about Layer 7 

1-      Select Traffic shaper option Under Firewall tab then select Layer 7 option.
2-      Hit “+” sign to create new layer 7 rule.
3-      First Enable this rule by adding check box then add name after that we can add description too
4-      Add rule here by clicking on “+” sign. Add Protocol, structure and Behavior
5-      Save and Apply Setting

We can add more here by hitting on + sign. More other ports, etc
After adding Layer 7 Rule we need to go firewall section to add layer 7 setting in option Rule under Firewall Tab.

1-      Select option rule under firewall tab and find out layer 7 option
2-      Pull down layer 7 option and select created layer 7 rule.
3-      Save and apply settings.

Port Forwarding



Port Forwarding:

Port Forwarding means to forward request through a specific port to the required Destination called port forwarding.
We can explain port forwarding with a reliable example.
If you want to remote any system that outside from your network then you can select MSRDP port and target our request to the destination with public source Interface.
According to the Pfsense I can explain with little bit description and print screen that will help to solve your port forwarding issue quickly. Follow instruction step by step.

1-      First we need to select  NAT option under Firewall tab.
2-      Add rule here after hitting on “+” sign
3-      In this  page we will add
     Interface(WAN interface)
     Protocol(TCP/UDP)
     Destination(any)
     Destination Port Range(From: MS RDP       TO: MS RDP)
     Redirect Target IP ( Machine Ip that we want to Access)
     Redirect Target Port( MS RDP)
     Save and Apply changes
That’s all for port  fording in PFSense. I attaché here print screen for more help.
If we have multi wan in network then we can add more rules under firewall tab NAT option. This way we can reduce the down time .
