apache

ifconfig lo:0 192.168.21.250 netmask 255.255.255.255 broadcast 192.168.21.250 up

route add -host 192.168.21.250 dev lo:0

route add default gw 192.168.21.49

 

echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore 

echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore 

echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
