So Sensei was working before the upgrade but now it is failing to find the python library:

```PHP Fatal error:  Uncaught Error: Class 'Phalcon\Config' not found in /usr/local/opnsense/mvc/app/models/OPNsense/Sensei/Sensei.php:113```

So I was using pfSense but the upgrade to 2.5.1 broke (failed to detect partition) so I decided I would give OPNsense a try.

I have two VLANs for now 192.168.0.0/24 (VLAN1/LAN) and 10.0.10.0/10 (VLAN10/10G).  All my network devices are plugged into a Dell N1524 switch and the ips for the VLANs on this switch are set to 192.168.0.252 and 10.0.10.254 - gateway is set to 192.168.0.254

In OPNsense I have setup the interface for the LAN as 192.168.0.254 and for the 10G network as 10.0.10.252 - both have IPv4 Upstream Gateway set to Auto Detect. 

Traffic seems to pass freely from both networks to the internet but when I connect from my workstation on the LAN to the 10G network the connection drops after 30 to 32 seconds.  With SSH the connection drops and with RDP the connection freezes after around 30 seconds and then it eventually reconnects.

This setup was working with pfSense but I've heard good things about OPNsense so want to persevere.

I've attached the firewall rules I have for LAN and 10G.
