Chapter 4 - Layer 3 Command Set - IP Networking Ipfw Command (IP Firewall)
Alvarion BreezeNET B130/B300 GigE 187 Operational User Manual
IP Firewall registers all rejected packets, writing appropriate message in the
system log. Registering all accepted packets may be additionally requested by
putting a log keyword:
ipfw add accept log icmp from 0/0 to 0/0
The above command will register all incoming ICMP packets.
CAUTION
A large number of logged packets may cause system log overflow (if you have redirected log
messages to a remote workstation).
