Pings on the internal network to the firewall server are being blocked.

[FosterSM]

I have just noticed that on my internal network I cannot ping my firewall server all other destinations internal and external are fine.
I expect that pings from the internet to the external interface should be blocked but not the internal ones.
I am currently using v2.1.1.
My config file:
firewall.conf.txt
What do I need to change.
Thanks

Hi @FosterSM : diff'ing your config from the default firewall.conf, you have many changes, among them:

 # Enable to ignore all ICMP echo-requests (IPv4) on ALL interfaces.
 # ------------------------------------------------------------------------------
-ECHO_IGNORE=0
+ECHO_IGNORE=1

Try setting ECHO_IGNORE=0 which is the default.

Thanks for the help, ping now works.
Is there anything else in my firewall.conf that is wrong, it has evolved over different releases of the the firewall and I am now concerned that it may be compromised.

@FosterSM : A quick look, nothing jumped out at me.

Possibly a good idea would be to diff your current config with the default and revert to the default any changes you don't recall doing.

For v2.1.1, the default firewall.conf is:
https://raw.githubusercontent.com/arno-iptables-firewall/aif/2.1.1/etc/arno-iptables-firewall/firewall.conf

I have checked with "SheildsUp" everything is green apart from port 445 which is shown has closed.

I will review my firewall.conf thanks.
