pfsense allow ping only from 1 ip

Hello,


We are a dutch company with an office in the USA.
the usa has an pfsense firewall. For this example there ip is 182.12.12.12

we have an ip for example of this: 100.12.10.12

Is there any way that we can set up an rule in pfsense that we in the netherlands can ping 182.12.12.12 every 5 mintues(we already have a program for that) but only we can so i cant ping the usa office for example when i am at home.

If so where can i set that up in pfsense?
