If you look at:
Pop3 Proxy
You'll notice that the 2 filter options come in the following order.
Expression Filter:
File Extension Filter:
However if you look at the SMTP Proxy you'll notice they are flipped.

When reading the "Online Help: ICMP" it says the following:
:: Ping settings::
These options apply only to the ICMP traceroute sub-type. To make your firewall answer ping packets, activate the Firewall is ping visible function. To make your firewall forward ping packets, select the Firewall forwards pings option. To be able to use the ping command on the firewall, activate the Ping on firewall function.
There are a number of mistakes in this however the one that should be noted is 'Ping on firewall function' there is not such choice. Should it read 'ping from firewall function'?
