To do this, we will navigate to Firewall > Aliases:Īs you can see, we can create aliases for IP, Ports, and URLs. Therefore, let’s configure two aliases: one for SSH and HTTPS and the second one for the hosts 172.16.100.200 and 172.16.100.201. With aliases, instead of specifying the individual objects, you just specify the alias name. This feature is similar to object groups on the Cisco IOS, where we group similar objects together to make configuration simpler. I decided to include this policy here so that we could see another feature available in pfSense – Aliases. Let’s leave this rule configured but, by walking through the steps of configuring firewall rules for policy #3 and #4, you can understand how this rule was configured. In the last article, we configured a firewall rule that allows ICMP from the DMZ to any destination, as shown below: Therefore, we don’t need to do anything extra to configure this security policy. Keep in mind that, if you are using DHCP, the host PC’s IP address may change from the one you configured in the firewall rule and you won’t be able to access the webGUI anymore (depending on how strict your rule was).Īs we have seen above, all traffic (IPv4 and IPv6) from the LAN is permitted by default. Therefore, I will leave the rule for WAN access open.
#Pfsense vlan priority Pc#
Note: Because I’m trunking the VMware interface used for both LAN and DMZ, I may not be able to access the webGUI from the host PC anymore via the LAN IP address. Let’s configure a sample security policy as follows: This is similar to how a Cisco router processes access lists, so one should be careful to put more specific rules at the top so that they are matched before generic rules. This means that any traffic seen on those interfaces will be denied, even traffic destined to pfSense itself!Įxcept for rules defined under the Floating tab, firewall rules process traffic in the inbound direction only, from top to bottom, and the process stops when a match is found. Hint: In that article, we also saw that there are no firewall rules defined by default for new OPT interfaces. We can view/configure firewall rules by navigating to Firewall > Rules:
However, all connections from the WAN are denied.
#Pfsense vlan priority install#
When you install pfSense, all connections from the LAN are automatically permitted by default. In this article, we will take a deeper look at configuring firewall rules on pfSense.Īmong the most important features you will configure on a firewall are the firewall rules (obviously). In that article, we also touched a bit on firewall rules. In the previous article, we set up VLANs on pfSense so that we could use pfSense for inter-VLAN routing. Welcome back to this series, in which we discuss and configure the various features of pfSense.
