Hi, I am getting following on this server. ####### [root@xxx root]# iptables -t nat -A PREROUTING -s 192.168.0.0/24 -d xxx.xxx.xxx.xxx -i eth1 -p tcp -m tcp --dport 3128 -j DNAT --to-destination 10.0.0.2:80 iptables v1.2.7a: can't initialize iptables table `nat': Memory allocation problem ######### But on other servers with exactly similar configuration and setup, I have not faced this error. Any clue to solve this problem. Thanks Perhaps iptables or your kernel needs to be upgraded. __________________________________ Do you Yahoo!?
