Could you please make a video about Traffic Shaper with multiple WANs with different bandwidth? I have 2 internet connections, one is 40 mbit optic fibre and the other one is 90 mbit LTE. I want to use them for load balancing, but the issue is the whenever the LTE connection hits it's limits then the loaded latency goes to like 400 ms. Unloaded is like 23ms. When I set a traffic shaper and limit the connection speed to 70 mbits the loaded latency is just 53 ms. But the issue is I cannot set this traffic shaper to be per interface, instead I have to use the limiters in the LAN firewall rules, which limits the whole connection in the load balancing lan rule. I can't find a solution anywhere and I've been looking a lot. I thought I should be able to do it via the Traffic Shaper > By Interface, but nothing happens when I edit things there. What's going on? Please help!

@PowerUsr1 Год назад

Came back to this video as I had a client that needed failover. Just….really great stuff you have here Tom. Seriously. The Netgate docs are so good it just makes the whole thing easy. Makes me wonder why other vendors make networking much harder than it needs to be (Larger enterprises not counted).

@urzu181 Год назад

But also to be noted that if you have different subnets/vlans that you need to access from your LAN side and you set the rule to use the gateway group for loadbalance/failover, you won't be able to access those other subnets/vlans. For that you'll need to create separate rules on top of the gateway group rule to allow access from LAN Net/LAN Address to the other subets/vlans using the default gateway.

@shempasta Год назад

Had this problem. Why does this happen?

@SuperDydx Год назад

@@shempasta because your one "allow any" rule on the LAN side forces traffic out the load balanced gateway group, which won't contain a route to your VLAN. You just need to change your one "allow any" rule to only be applicable for traffic which would be leaving your internal network, and create more rules to allow LAN to VLAN traffic.

@shempasta Год назад

@@SuperDydx Thank you for elaborating!!

@Max-jv3yg 6 месяцев назад

This is such an important comment and should of been vital to this video. The best/easiest fix for this is to create a RFC1918 alias, then create a rule ABOVE the gateway rule to send traffic to the default gateway. The pfsense Docs actually cover this in good detail; search Google for “pfsense bypass policy routing”. In addition to this, it’d be a good idea to block RFC1918 addresses from traversing the internet. Without the above rule in place, traffic destined to a local address (ie. 192.168.1.x) will actually go out the WAN interface(s). Search Google for “Preventing RFC1918 Traffic from exiting a WAN interface”. Maybe Tom can create an updated video in 2024 to include these important details. Hope this helps.

@MT-yo3mg Год назад

Gosh Tom, this video just cost me 30mins... :-) (great video though, thanks!). Watching it got me creative and made me subscribe to a 2nd vpn provider, so I could group the 2 for failover functionalities for my guest-lan, so they could go out forced via the tunnels. After creating the openvpn client, all my local clients lost connectivity.. Didn't get it at first, but then discovered their dhcp provided my openvpn client with a lease which overlapped with one of my local subnets. Bringing it down restored connectivity again! :-) Changing it on my end would mean alot of work unfortunately, so I'll check out another VPN provider I guess :-) Just wanted to share; keep up the great work! Appreciate your videos a lot! greatings from The Netherlands!

@HansVledder Год назад

Excellent video Tom! Tip: under System / Routing / Gateways (pfSense v2.6.0-RELEASE) you are provided the option to set the system wide default gateway(s). When selecting either a Failover or Load Balancing gateway group, either one of them is set system wide. No additional firewall rules needed.

@LAWRENCESYSTEMS Год назад

Nope, you still need the gateway rule for the LAN or the load balancing plan will not work and while failover will work if you set that but it will force switch the gateways and disrupt connection when a failover member comes back online.

@jerryfaircloth Год назад

Great video Tom, some of the things some folks run into though would be as one of the paths starts to saturate the gateway down detection will start to think the link is down and switch gateways erroneously. You can add some prioritization to fix that but it would be best to use AQM like CODEL. And I am not sure if pfsense still has a bug using CODEL on dual WAN's or not. I switched over to OPNsense about a year ago because of that. It still does not work perfectly with CODEL but better than pfsense at least in my case.

@fredbrunken502 Год назад

Love your videos about pfsense. In this case though, there is one, very important information, that was overlooked. The DNS setup, under SystemGeneral Setup, you need to assign one GW for each DNS you have. Otherwise you start having problems with DNS resolver.

@unmesh59 Год назад

My ISP is beginning to have outages more often and this video has me thinking I should get a hotspot with an Ethernet port from a mobile carrier and set it up as my failover WAN. I have several LANs, however, and I was wondering if there is a single setting to get all of them to use the failover gateway group or whether I have to do it for each of them individually. On a similar note, if the firewall for an interface has several rules, does the gateway have to be changed for every rule indivdually? (I suspect the answer is yes)

@spreenjeff 4 месяца назад

how do you force 1 lan ip address, to force to use a backup wan, so it can be on that wan, and the rest of network uses the default wan... or can u have a 2nd set of failover wans the specific devices can use?

how do you set this up if there will be an additional two switches after the pfsense? does this mean that my pc should have 4 NICs or could I use a splitter to transfer the connection from the pfsense to the two switches?

@brunosolothurnmann9205 Год назад

Thank you. I successfully installed on pfsense dual wan. I workes fine, except of the VLANs. I can't use the Gateway Group for the LAN. I saw now what urzu181 wrote. As I'm not a professional, I was not able to extend the firewall rules, so that it will work as expected. For each VLAN I created on LAN a rule for local traffic with the default gateway. As the last rule I use the gateway group loadbalance. I appreciate very much if you could let us know an example for VLANs.

@LAWRENCESYSTEMS Год назад

You need a rule for load balance or fail over rule each VLAN

I have two separate internet connections on my pc. One is from regular lan cable to router. Other is over mobile hotspot 4g internet connection. I wish to utilize both at the same time on my pc. Is that possible? Is there software on windows system that can support such use of two separate internet connections at the same time. My main issue is that I have better download speed on one of them, namely the Lan connection. While my upload speed is better of the 4g. I would be using lan internet for regular playing and connectivity, while I would be using 4g to upload my stream. However I am open for any suggestions you can give me. Thank you upfront for any useful comment you guys provide.

@PowerUsr1 Год назад

I need clarification when it comes to failover. If i have 2 upstreams, Tier 1 and Tier 2. Tier 1 fails and now Tier 2 is primary. Once Tier 1 is "fixed" does that bring Tier 1 back to primary again? My second question is, if my primary Tier 1 circuit goes down can you make it so that if it does come back up again it is not used as primary? Maybe you want to bring it back in service during a maintenance window as to not cause an outage

@LAWRENCESYSTEMS Год назад

If Tier 1 is primary and Tier 1 fails Tier 1, Tier 2 becomes primary, if you have the LAN Gateway rule Tier 1 coming back does not disrupt users because it just offers a favored path, but does not force the use of that path.

How do you load balance with multiple VLANS already in place?

@Zeric1 10 месяцев назад

It's just like the video shows for LAN. You have two options, one can change the default gateway (System>Routing>Gateways>Default gateway) from WAN_DHCP to the balanced gateway group you created so it will apply to every LAN/VLAN that is using the default GW. The other option is to go into each VLAN and change the firewall rule that allows traffic to the internet (typically the last firewall rule for the LAN or VLAN in question) from the default gateway to the balanced gateway group. Note, it's an advanced option for the firewall rule so you will need to click the "Display Advanced" button first.

You could make an Video about HA pf/opn sense. But with 2 different hardware boxes, or an physical and virtual instance. Dual-wan in pf/opnsense is something that already everyone knows and there are 200videos about and 1000 google results including official documentation. About ha on different hardware connecting to one pppoe connection (active/passive), since you can logon only with one box to pppoe and not both at same time. That sort of videos doesn't exist. Cheers

@@LAWRENCESYSTEMS luckily i have 2 proxmox nodes here. If one node goes down, i still have internet access because the vm on the other node goes up. Luckily i have my opnsenses virtualized and proxmox has a nice way to realize such things with scripts. The thing is, i need to reboot my nodes, because of updates/bios updates etc, once i wasn't at home and family made with a mixer a short. The server turned off, the other Server started the opnsense instance and they had still internet, till i returned. Such cases happens quite often in every home. And i seen already an HA discussion about pppoe failover, there is even an plugin for it. So HA failover looks like a more teliable way to me. Different hardware is no problem either, since you can explicitly select what you want to sync, it's just not very granular. And i see nothing that speaks against it. Just didn't had time to realize it myself. I mean if you don't want to make an video about that, that's absolutely your free will, im just saying that such videos, who everyone on the planet already knows, make no sense to produce. Additionally to that, that almost no home user has 2 internet connections. That's only sth for some businesses, but i doubt that any of those watch your channel. They have usually a contract anyway with an it company that supports them. So dunno actually who you even want to reach. Cheers
