PFsense generates ping from wan every minute. Firewall will not block ICMP
-
First off PFsense is awesome. Much kudos.
I noticed every minute my WAN pings my router about every minute, with no fail.
I can find no documentation anywhere about this.
I have surveyed all my local machines very closely to see if they cause this, although I did not have this problem before using PFsense. Sure enough not a trace of ping is seen inside my LAN.
So I set out to make firewall rules, at first blocking ICMP echo from WAN, it did not work.
So then I used the specific IP of my WAN, rather than the variable " WAN address ". Still pinging from WAN every minute.
Is this normal? I don't like the feeling it gives me when I have backdoor pings generating from a un-known source. I would think it is my fault specifically but when firewall rules do not stop it, I can only assume something of the build of pfsense is hardwired into the system generating these pings.I would seriously appreciate someone w/ a answer to reply, as I am about to drop it and just use pf. If my firewall OS is not completely under my control, it is not what I want.
Thank you and good day.

Afaik the tool behind the RRD graphs pings the WAN once a minute to generate the WAN link quality graph.

This totally is what my problem was.
Someone give this guy a raise!
Thx much, I will keep enjoying this awesome firewall. ;D

Well i wouldn't consider it a problem.
Just something to know :)You can disable the RRD graphs under:
Status –> RRD Graphs --> Settings
and then uncheck the "Enables the RRD graphing backend." checkbox.
