hi jeffrey,

thank you. :)

i modified my iptables as following:

    $IPTABLES -A udp_packets -p UDP -s $ALLOW_IP --sport 
$CLIENT_AFS_PORT --dport 1024:65535 -j allowed -m conntrack --ctexpire 600
    $IPTABLES -A udp_packets -p UDP -s $ALLOW_IP --sport 1024:65535 
--dport $AFS_PORT -j allowed -m conntrack --ctexpire 600

it became more stable. but, i still can see "Lost contact" in the system 
logs(/var/log/messages) from time to time. could i adjusted any settings 
to improve this problem?

thank you for your useful helps!!

best, sam
