nat with iptables, re-connecting fail within about 3 minutes
- by xpu
i constructed a nat with iptables, as following:
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -I PREROUTING -p tcp --dport 9000 -j DNAT --to xx.xx.xx.xx
iptables -t nat -I POSTROUTING -p tcp --dport 9000 -j MASQUERADE
service iptables save
service iptables restart
the configuration worked fine, but there was a problem when i disconnected and tried to reconnect again, connection will be refused within about 2~3 minutes, after that, things go fine again.
what was the problem? how do i make it to accept new connection after the old one break?
