OpenVPN as client with dual WAN

[naltalef]

Hi.
I need to migrate to OPNSense a firewall that currently is running on OpenBSD and functions as an OpenVPN client for several servers.

It has two internet links and in each case one is used as primary (active) and the other as secondary (standby).
To get this in each OpenVPN client there's a config file such as the following:

# Primary
<connection>
        remote REMOTE_IP 1194
        local LOCAL_IP1
</connection>
# Secondary
<connection>
        remote REMOTE IP 1194
        local LOCAL_IP2
</connection>

In the case that one of the links fails, an external script restart each OpenVPN daemon in order to establish the VPN using the secondary link.

My inquiry was about implementing this one function into OPNSense and having it work in a similar manner.

I will be grateful for any suggestions you can make.

Regards
Norberto
