Hello,
I recently started with a new company as a Sys Admin, their Network Admin just left. They have been having some issues with their fail-over connection using too much data and have ask me to look into it.
At my office we have an MX84. Wan 1 is configured with a Comcast fiber connection, Wan 2 is a Verizon LTE connection via a Cradlepoint Router in pass-through Mode. I have the MX84 configured to use WAN 1 for the primary and only to use WAN2 in the event of a fail-over.
VPN Topogrophy: We have 10 other offices and 1 data center, the satellite offices are all using MX84's as well and are connected via VPN utilizing Meraki Mesh. The Data Center is using a ASA 5545, it has IKE V1 connections to all of the MX 84's including my office.
The issue we are having is that even though there hasn't been a fail-over, we are still consuming 18GB of LTE data a month and incurring overages with Verizon (the plan the company had was to pay for the 1GB per month plan and upgrade to a larger data package if needed in the event of a failover). I would argue to just keep the higher plan, but those decisions aren't left to me and here we are. I believe that its the Active/Active Auto VPN that is causing the excess data usage, but I can't figure out how to disable it for WAN 2.
Any help or information would be greatly appreciated.
Best Regards,
SML I.T.
