Cannot ping Remote Site to Site
My client bought a USG20-vpn appliance rather than a Ubiquiti USG appliance.
Since I got lemons, I'm making lemonde.
The Zyxel is now up and working and connected to a remote pfsense appliance for IPSec VPN.
The issue I have is I cannot figure out why I cannot ping remote hosts.
My other IPSec connections to other sites with the pfsense are working just fine.
Is there a rule or something not configured properly?
Here are the rules configured on the Zyxel.
Any help would be appreciated.

Hi @Nappy_d,
It is probably blocked by the pfsense and you need to create a Firewall Rule on pfsense.
Navigate to Firewall / Rules / IPsec. Click on Add. Enter values as the following:
1. Change Protocol to Any
2. For Source select Network
3. Enter the Subnet of USG.
4. Enter a Description
5. Hit Save & Apply Changes
