Proper way to do fail over wan?

elementalwindx

I've got an office going with the newest pfsense released. Today their cable internet died out and some people were able to get online and some people could not. No idea why. When I changed the default gateway to the working DSL under system -> routing -> gateways, everyone was able to get online.

Here is how I have it setup:
system -> routing -> gateways
2 gateways, 1 cable, 1 dsl.
Both monitor 8.8.8.8, or 8.8.4.4
Primary is the cable because of the highest bandwidth so it's set as default (or was till it comes back up)

Under Gateway Groups:
I have 2 groups:
Failover1 (If CABLE fails go to DSL) Tier 2, Tier 1
Failover2 (If DSL fails go to CABLE) Tier 1, Tier 2

Under firewall -> rules -> lan
I have 2 rules created:

12 /7.50 MiB IPv4 * LAN net * * * Failover1 none If CABLE fails go to DSL
0 /0 B IPv4 * LAN net * * * Failover2 none If DSL fails go to CABLE

Any idea what I am doing wrong here?

Or maybe it's just that the DSL connection just doesn't have enough bandwidth to handle a server and 10 desktops. Ughhhh.
