Disabling WAN connection after a certain amount of traffic?

[Sanek]

Hello!

I have 2 different WAN connections from different ISPs that I'm load-balancing. Unfortunately, the second connection has a monthly bandwidth cap (90GB), while the primary connection does not.

Is there a way for me to utilize both connections until the traffic limit is reached on the second connection and then to disable the second connection until the next month?

Thank you in advance for any help!

what happens when you exceed the 90GB cap ?

if the provider shuts you down completely (no pings get out) then the gateway or monitor ip should automatically go offline

They start charging overage fees ($1.75 / GB I believe) :(
