Use ipfwadm to do this. This assumes you have firewalling compiled in the
kernel.
ipfwadm -I -a a -P icmp -S 0/0 -D mymachine 8 -W ppp0 -o
The "8" represents ECHO_REQUEST or you can leave it out to log all ICMP
messages. "mymachine" should be substituted with the hostname of your
machine. The "0/0" represents any host trying to ping your machine. The
"-o" is to enable logging.
The "-I" is for input, and "-a a" is to accept these messages, and
append on to the end of your existing (if any) list of fw rules.
"-P icmp" specifies this rule is for the ICMP protocol specifically.
