Hi, I've been working on replacing my Raspberry Pi which is today my OpenvPN Server.
I'd like to have my ER-Poe5 as OpenVPN Server.
It's been a week of complete Reset the device bescause I'va made incorrect settings and distroyed my actual setting...
Here is the topology of my Network :
ETH0 (WAN1) => 4G Modem (yes I know, I've got 3Mo of ADSL...) can't BRIDGE the modem
ETH1 (WAN2) => ADSL can't BRIDGE the modem
ETH2 => IP CCTV
ETH3 => Ubiquiti UAC Pro
ETH4 => LAN
Switch => ETH2 + ETH3 + ETH4
LAN for ETH0 is 192.168.8.0/24 subnet
LAN for ETH1 is 192.168.1.0/24 subnet
LAN for SWITCH is 192.168.10.0/24 subnet
The actual setting is that ETH1 is failover ETH0, so when I loose my 4G connection I've got the ADSL connection : that's working lovely !
Now what I want is the following : I want OpenVPN server working as it is today with WAN failover, and when I want to connect to it, it should use the ADSL connection to get to my LAN from outside.
I hope you'll understand my problem and have any idea what it is not working today
I thinking my problem is a NAT thing but I can't figure it out...
Here's a cat of my conf :

THANK YOU for having a look at it !
Sorry for any mistakes I'm French.
