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

please give me some hints. thank you.


Expire your NAT udp port mappings less aggressively?

NAT UDP port mappings should have a lifetime of at least ten minutes.
