pinging same host on the internet from two different LAN stations

[Pejman Moghadam]

Hi there
I have one FreeBSD 5.4 router/firewall box in my LAN that do NAT with PF.
The problem is I can't ping the same machine on the internet from two or more different machines
on my LAN at the same time. only one of my LAN clients can ping that target, and pinging that
target from another station is possible only when i stop pinging from first client.
Is there any way or any tool that ICMP portmapping allows simultaneous connections to external
targets from multiple machines from the LAN?
Thanks in advance
