Issues configuring pfsense 2.3.2 with NordVPN

[zbone]

Hi,
I am trying to configure the new pfsense box to work with NordVPN following article here:
https://support.nordvpn.com/hc/en-us/articles/207875115-pfSense-router-setup
with no avail.
VPN connection looks like being established ok but nothing gets through for some reason.
My network config is as follows:
ISP->pfsense box[int 192.168.1.1]->WDR3600 router [192.168.1.2]–cat5-->PC [192.168.1.100]
It's a fresh vanilla install by default except having 8.8.8.8 and 8.8.4.4 set as DNS as shown on the screens.
Everything works fine.
Then I applied the steps as listed in the article below along with a restart in the end.

What happens is when I connect to VPN all IPv4 traffic apparently gets blocked as shown on the screens 10-13. I have very limited networking knowledge and out of my depth trying to troubleshoot it. However, I am pretty certain it's not a VPN issue as I have experienced similar symptoms with ExpressVPN as well and need assistance navigating through pfsense config.

Your assistance would be of great help.
