Does pfsense support multi wan on same gateway on multiple interfaces
-
Reason I ask is because I am pretty sure one of my connections is down but it still says online. When I check my ip address, it always comes up as the first modem.
I am doing load balancing and failover, but I do not think it is functioning correctly. Anyone else have any advice?

As far as I know it does not support this. It doesn't matter if there is just one interface with VLANs or different interfaces on pfsense. The reason is the gateway.
Probably you already read this on the forum: You can use double NAT to get different gateways.
-
Can't do that, each WAN must have a unique gateway IP.
-
when you say double nat, do I have to buy another cheapo router to accomplish that? Or is there some magic I can do?

Generally people do it in the modem as well as the firewall in that case, or if your modem has no ability to do so, yes a cheapo router will suffice.
-
Yes, I use somecheap router which only does NAT. The firewall is disabled so there is not much load on that router and the firewall settings can be all configured on pfsense.

You can use the same gateway, i do that and work fine!!
You need to setup a different monitor IP address for every WAN, and configure monitoring for packet loss or high latency, for it to detect when they are offline.

it's not working for me, even with different monitor addresses.
i will see how the dx-e402 goes, I just bought it for 10$.
Now to play the waiting game, will post back to tell you guys if it's poop.

No it won't. It'll only use one of the connections that have the same gateway IP. It may rotate unpredictably between them, but generally will stick to only one of them.

I'm using it with 2 PPPoE wan that have the same gateway, and the two WAN are being used with no problem.
But if I don't change the monitor IP it can not detect when only one of them is offline.

Ah, should have clarified, in 2.0.1 and newer you can indeed use multiple PPPoE connections with the same gateway. That's not true of any other type of connectivity.
-
No, It won't work. I tested it and it only use one connection while the other one just idle
I don't see any point having two different WAN with same gateway….

No changes are needed in the Monitoring Gateway IP anymore? Both connections can be using the same gateway?
So for all who are atm using a cheap modem/router for the second WAN(PPPoE), we can just switch WAN2 to PPPoE, remove the cheap modem/router and have full functionality?
(having setup Load Balancing correctly) -
You have to have unique monitor IPs, but with PPPoE you can have multiple PPPoE connections with the same gateway in 2.0.1 and newer.

great! thank you very much!

So if I have two simple ethernet-wan connection:
IP address 212.55.80.123
Subnet mask 255.255.255.0
Gateway 212.55.80.10
2.
IP address 212.55.80.124
Subnet mask 255.255.255.0
Gateway 212.55.80.10Can I use It on 1 pfsense server? I must to setup a different monitor IP address for every WAN, and configure monitoring for packet loss or high latency, for it to detect when they are offline? Or it not possible?
-
To make load balancing or failover work when both connections have the same gateway you must:
Be running 2.0.1
Be using PPPoE
Configure different monitoring IPs on each connection.Steve

Was wondering about this. Have got 24 PPPoE ADSL's that i would like to load balance. Gateways would unfortunately be the same for all from service provider. Would be a problem to find 24 different ip's to monitor. The other problem is the gateway ip is the ip that would be pinged to test latency. Saw a lot of times people say set up PPPoE on modem, but this will break fail over. If PPPoE on modem is down, PF Sense will se the ip to the modem and you cant use ping because of above mentioned ping problem. So sad, to bad. :-)
