Firewall – pfSense allow ping only from 1 IP address

firewallpfsensepingrules

We are a dutch company with an office in the USA.
This office has an pfSense firewall device with the 182.12.12.12 IP address .

In the Netherlands' office we have an IP address like this: 100.12.10.12

Is there a way that we can set up a rule in pfSense that we (in the Netherlands) could ping 182.12.12.12 every 5 minutes (we already have a program for that) but just from the Netherlands' office so I can't ping the USA office let's say from my home.

If so, where can I set that up in pfSense?

Best Answer

ping uses ICMP protocol. So basically you need to add/edit a rule in your pfSense firewall to allow ICMP echo requests if the IP address is 100.12.10.12.

Go to Firewall > Rules and add a new rule which should have above criteria.

Action > Pass, Interface > WAN, Protocol > ICMP, Type > Echo request, Source > 100.12.10.12, Description > Add description

Then click Save

This should do it.
