Need help, 2 WAN, 1 LAN, Load Balancer

This is now fixed in CVS. If you are running a full version then issue this command from a shell:

cvs_sync.sh releng_1

Next go to System -> Static Routes and create a "Interface Gateway checked" route through the correct WAN interface with the destination being the DNS server/32. Repeat this for any other DNS servers.

This will force traffic for the DNS server out the correct interface and will solve this problem during WAN port down times.

Hi Scott,

Just had a look at the static route form and I dont have this option to select the Interface as a gateway there. Is this option been included in the latest snapshot. I am using a full Beta2 version less snapshot.

Thanks Scott,

I give this a go later tonight after work finishes and I have time to play with it a bit.

Thanks for all your help.

I just realized that this was breaking the routing in certain situations so I have removed it.

The way to force the gateway correctly for DNS is to put in the next hop router to force the traffic out the correct pipe.

Sorry about that!

May you explain in more detail?

What's "next hop router" in your situatioin?
e.g. if WAN-1 ISP gateway is 111.111.111.1, will that be your next hop router?
What about WAN #2's gateway? What should we do about it?

After one figured out what's their "next hop router", where should they put "next hop router" info in pfsense? e.g. on which configuration page, under what options? Thank you.

sullrich

Whatever the gateway is of that interface.

For example if your wan is fxp0 do:

route get default fxp0

Then use the gateway listed as the next hop gateway.

Actually it's a copy/paste error it should be LAN (source) (169.254.1.0/24)

Sorry about that
