DUAL WAN setup doesn't work
-
Which tutorial did you follow?

I followed these tutorials:

http://www.tecmint.com/how-to-setup-failover-and-load-balancing-in-pfsense/2/

The tutorial looks comprehensive. Did you configure the gateway monitoring and its trigger parameter? That has to be configured properly in order for the Load balance fail over to work.
Also, check your DNS and make sure both ISP has its own DNS under general setup
-
No i didn't configure those cause that wasn't suggested in the tutorials and isn't suggested in the pfSense book. I also tried to configure a fail over only (no load balance) and it doesn't work.. However i can succesfully do a tracceroute via my 2nd wan to the internet.. Do you have any suggestions what i should configure for the trigger parameter?

I am really surprised that it is not covered either in cookbook or in the tutorial. Please see my screenshot as reference.
You can configure gateway monitoring under routing > gateway > edit gateway
 -
Ok thanks i'll give it a try.. Are those settings for both gateways or just one..
And or the other settings left on default > see attachement..

My dual-wan setup works best when using Open-DNS for GW monitoring. My setup is load balanced, with failover in case one WAN goes down.
I originally used Google DNS 8.8.8.8 & 8.8.4.4 but found the failover was unreliable. After changing to Open DNS addresses, it worked great. Since then I have found out that using same IP for GW Monitor and System DNS causes problems where clients try to use the wrong DNS. See this thread https://forum.pfsense.org/index.php?topic=83721.0
So now I have Pfsense & Google as client DNS, with OpenDNS as GW monitors.

Great to hear that it works well for you.. What tutorial(s) have you used to setup multi WAN on your pfsense. Maybe you can help me out to configure mine properly since i can't get it to work…
-
Perhaps not obvious but if you are using dual wans, you must manually add LAN firewall rules selecting the load balancing gateway group as the gateway (this is in advanced options). If you have multiple lans, and you are trying to direct traffic from one lan to another then you must also add rules using * (default) above the gateway group rule.
This is not explained very well in the multi-wan documentation.

I already added the rule(s) on my LAN Interface… I configured the advanced options under gateway settings but it still doesn't work...
