<![CDATA[Issues with OpenVPN on pfSense 2.4.5 <-> Robustel R2000-4L]]>I am trying to connect these two devices (and their networks) with an OpenVPN tunnel.

If it matters, the pfsense end has publically routable IP and the robustel end is behind CGNAT. I've had a setup like this (albeit between OpenVPN and OpenWRT) working before but this one just won't work. Feeling pretty defeated. If anyone could take a look at my configs & logs below and give me some insights that would be amazing.

Here is the config on the pfSense end

cat server3.conf
dev ovpns3
verb 6
dev-type tun
dev-node /dev/tun3
writepid /var/run/openvpn_server3.pid
#user nobody
#group nobody
script-security 3
daemon
keepalive 10 60
ping-timer-rem
persist-tun
persist-key
proto udp4
cipher AES-128-CBC
auth SHA256
up /usr/local/sbin/ovpn-linkup
down /usr/local/sbin/ovpn-linkdown
local 80.196.79.35
ifconfig 10.8.0.1 10.8.0.2
lport 1194
management /var/etc/openvpn/server3.sock unix
route 192.168.0.0 255.255.255.0
secret /var/etc/openvpn/server3.secret

and here's the config at the robustel end:

# show openvpn all
tunnel {
    id = 1
    enable = true
    desc = TotRDC
    mode = p2p
    tls_mode = none
    route = ""

I gave up trying to get OpenVPN running on the Robustel. I instead used a OpenWRT based router to connect to the very same pfSense, had it working in under 10 minutes.
