Issue with LAN interface after installation on Fitlet2

[aks0811]

Hi,
I've installed the latest pfSense onto a new Fitlet2 but can't get past an issue with the LAN interface. I was able to get an IP address on the WAN port from my ISP without any problems and I set the static address 192.168.1.1/24 on the LAN port. I'm able to ping 192.68.1.1 in the pfSense shell as well as curl from the shell to http://192.168.1.1 to see the login page content of the web ui. But I can't ping 192.168.1.1 from my pc attached to the LAN port directly nor via a switch, or see the web UI login page via http. I tried setting a static address on my pc and also tried to get an address via dhcp but it won't connect.

I'm out of ideas and would appreciate any help. I can see others on the forum running ok with a Fitlet2. Are there any firewall settings I need to change first, that can be done from the command line? Perhaps I've overlooked something simple.
Thanks
Alan
