Multiple OpenVPN tunnels between the same sites

[madas]

Hello all,

Here is my problem

Site A : Cable Modem + LTE Backup
Site B: Fiber

I currently have an OpenVPN server running at Site B and Site A connects (site-to-site tunnel) using an interface failover group. When the cable modem goes down the LTE backup brings up the tunnel and it works great. The problem is that the tunnel never fails back to the cable modem until i manually intervene.

I'm wondering if there is a better way to handle this?

Can I create two tunnels

Cable Modem --> Site B
LTE --> Site B

and give the two routes different metrics (lower metric for cable modem and higher for LTE) ?

Would appreciate some suggestions.

Thank you

M
