Pfsense interface groups
How to setup an alias in pfsense to simplify firewall rules
This shouldn’t be too difficult to execute. With port forwarding, you’ll almost certainly need code to divide the community into member interfaces. Outbound NAT might also require it. I’m not sure if interface groups are useful for outbound NAT, but if they are, they can need a separate line in the rules. debug for each of the group’s interfaces
All WAN can be selected in the screen where rules are edited for users who previously used Peplink Balance routers. Rather than creating a rule for each WAN link, Peplink creates a rule and uses checkboxes to pick one, more, or all WAN interfaces. Please see the screenshot attached.
The current implementation of 20100731-1322 is incorrect:
– using WAN1+WAN2 as a grouping of WAN1+WAN2- ‘firewall nat.php> will generate a rule for WAN1- creating a related filter rule, generates one for WAN1 (= correct)
– now you can edit the related filter rule, changing interface WAN1 to group WAN firewall rules edit.php?id=1>
– after saving, firewall nat.php> now displays ‘WAN’ && firewall nat edit.php?id=0> now displays ‘WAN1’ as interface (!= correct); html source of firewall nat edit.php?id=0> now displays ‘WAN1’ as interface (!= correct); html source of firewall nat edit.php?id=0> now displays ‘WAN1’ as interface (!= correct); shows: option selected=”” value=”wan”> option selected=”” value=”wan”> option selected=”” value=”wan WAN1 WAN1 WAN1 WAN1 WAN1 WAN1 WAN1
Create network interfaces for pfsense
*Using the aliases you created earlier, create firewall rules for each gui. This way, you can build a rule for the NIC you want to isolate, but you won’t be able to list every possible useful link scenario. Note that any link for which there are no rules will be blocked.
Furthermore, I avoid Some like the plague and use aliases wherever possible. In general, it’s best to try not to allow anything and then patch in any specific cases you want to block later. Instead, try to build a ruleset that only makes the traffic you want, and nothing else. This way, there are no unexpected surprises if you forget anything.
DerBachmannRocker has hit the nail on the head. More precise rules are required. Although I don’t believe that creating address objects for the networks is essential, you might use the “Interface Name here> subnet” alias, which is built in and ready to use by default, as a source/destination.
Another security note: Providing rules for ANY (with certain exceptions, such as ICMP/Ping) is never a good idea. Viruses that like to “phone home” to their command and control system are one of the most common explanations. That virus would get out if you had a law that said “ANY LAN subnet to ANY destination on ANY protocol.” Make a list of all the programs that are used on your network, as well as the ports that they need, and set up a set of rules to let all of them out. If you were infected by this kind of virus, it wouldn’t be able to leave your computer to do its dirty work. You must strike a balance between security and usability for users. But, for the love of all mankind, don’t take the less safe route just because it’s convenient. One day, it will bite you in the arse. Investing in good security is always a good investment.
Pfsense setting multiple static wan ip addresses / using
Per account, AirVPN allows for up to five simultaneous VPN connections. When properly configured, this can provide some failover security in the event of an AirVPN server failure or service degradation. One thing to keep in mind is that OpenVPN is single-threaded, which means that no matter how many processors or threads the CPU has, OpenVPN would be limited to a single thread. Load balancing through multiple OpenVPN connections to optimize throughput can be helpful, particularly on lower-spec processors.
The first step is to decide which servers are suitable for your needs. I choose servers that are located in a variety of datacenters that have the lowest latencies as compared to my location. ping can be used to calculate response times from the command line or the Diagnostics > Ping menu in pfSense.
For a set of servers located in the United States, this process generated the table below. Avoid choosing different servers in the same data center, which are usually defined by identical IP addresses, such as 220.127.116.11 and 18.104.22.168. Spreading traffic through several data centers mitigates the effects of a single datacenter outage or service degradation.
Pfsense – assigning the lan interface to lagg
Optional: iDRAC on the Dell server was shared with NIC0. It can be set up for a specific VLAN. If it could ‘enter’ VLAN10 (management) on the trunk on NIC 0, that would be the best option. I’m not sure if that’s possible, but it’s an option.
What is the right way to set this up? Isn’t a vSwitch needed for any physical NIC? I’m also assuming that vSwitch0 (NIC 0) has a port group for each VLAN, allowing internal VMs to link to it. It also has a port community linked to the pfSense VM with VLAN 4095 (passing all VLANs). If that’s the case, how do I bind (tag) NIC 2-5 to the appropriate VLANs? I suppose I’ll have to build a bridge, either in ESXi or pfSense?
Simply add all of your ports to the vSwitch, then build port-groups for each connection and set the relevant ports to be active while the rest of the ports are disabled. They simply linked each of the pfSense vNICs to the proper port-groups.
