Bridge OpenVPN (preshared Key) with Pfsense & Router Robustel

[Arduro]

Hi everyone,

I am trying to make OpenVPN bridge (preshared key) TAP, with Pfsense and a router robustel R2000-4L. I followed these guides:

https://docs.netgate.com/pfsense/en/latest/book/openvpn/bridged-openvpn-connections.html
https://www.backloop.biz/2016/09/16/stretched-lan-tra-diverse-sedi-con-pfsense-e-openvpn/

The server OpenVPN is enable and listen the port 1194, firewall rules were set in:

WAN firewall rules:

BRIDGE firewall rules:

LAN firewall rules:

The problem is that the router robustel is not able to connect to the VPN, all the settings in the router seems to be ok, but i dont know where could be the problem.

Checking the router i got some *.pac (with the snifer tool) and I got that these error in the packet captured.

" Malformed Packet" & "Nov 3, 2013 18:13:58.000000000 ora solare Europa occidentale (I am not sure if this is correct, I think it must be the right local hour of my region)", so I checked the hour settings of the router and this is ok.

Please your help
