Hello,
my linux redhat server allows users to go to internet and in our intranet on 
the server (192.168.1.10).
I use iptables.
Some requests are routed to a Win2k server (192.168.1.20) like:
iptables -t nat -A PREROUTING -p tcp --dport 59645 \
-d my.domain.com -j DNAT --to 192.168.1.20:59645
"my.domain.com" is my internet domain but the site is locate on the linux 
server.

Also i use Destination NAT Onto the Same Network in my iptables script like 
for internal users:
iptables -t nat -A POSTROUTING -d 192.168.1.20 -s 192.168.1.0/24 \
-p tcp -j SNAT --to 192.168.1.10

Users of my network are on win2k pro.
A software on the win2k server allows users to chat with the 59645 port.

Since i use this configuration, a console message appear in linux when users 
chat with the software:
linux kernel: NET: 3 messages suppressed
linux kernel: NET: 2 messages suppressed
linux kernel: NET: 5 messages suppressed

It is serious ?
There is no loss in chat, but what should i do ?
Thanks for your responses..

Thomas.
