Well, If I were you, I would draw my network schema and then I try to think
why there are some packet loss on my network, maybe because of long cables,
internet speed, packet jumps ( router devices ), big network traffic,
firewall state tables, other things you know.
Also it effects how many devices do you use in your network. For example
when a package try to goes to internet, how many routers is this packet
going through? For example 2 devices, 4 or 10? :)
Well my friend many things can effects for packet loss.
Your questions which is about pfSense ICMP limitations. I think, the
problem is not about pfSense or ICMP limitations.
I will make a check list that you can might be solved the problem after you
looked this things.
- State tables => Diagnostics > States ( Is it full? )
- RAM usage (dashboard)
- CPU usage (dashboard)
- TOP command for processes of services. => Diagnostics > System Activity
- Traffic usage => Diagnostics > Traffic Graph
Send here a picture of your gateways status please. Status > Gateways
I hope, you can solve the problem. Well, These are my thoughts, I wish I
could help you.

Post by DanielHi,
not sure. Problem is - I have in my network packetloss and we started to change everything.
Cabling, Switches and so on. On the thing what we didn’t changed was the firewalls.
So I installed Smokeping on a Server which is behind the firewall. I
configured to monitor WAN und LAN interface with ICMP and here I see some
loss.
All other internal Hosts has no loss just both Firewalls. Traffic which is
routed thought the Firewall is just few Mbits – So not overloaded or so.
I thing, or my opinion is that pfSense has some ICMP limitations which
shows me loss but this is just a case of some limitations.
But more funny is – I see the same loss on both Firewalls.

Hi Daniel,
I hope that I did understand you :). You should go to System > Advanced >
Firewall & NAT > at the bottom of this tab, you will see state timeouts.
There is ICMP timeout. If it's not that you're talking about, let me know.

Post by DanielHi there again,
just wanted to know if pfSense has per default any ICMP rate
Limitations
Post by Danielinstalled?
Problem is I see some small loss in WAN/LAN interface but actually I
have
Post by Daniela any/any rules.
I see this on both firewalls I have installed.
Cheers
