I did a perfect build of CentOS 6 for ISPConfig 2 on my LAN (192.168.10.0/24) and then moved the server to my WAN (23.XXX.YYY.160/29) and changed all of the appropriate files. The server works fine on the WAN, but there is no connectivity within MY tiny little /29 subnet. In my case, my firewall/router has a public IP of 23.XXX.YYY.162/29 My webserver has a public IP of 23.XXX.YYY.165/29 Both share a gateway of 23.XXX.YYY.161/29 If I ping my firewall/router (it is pingable) from WAN, I get replies. If I ping my webserver from WAN, I get replies I can not ping my firewall/router from webserver or vice-versa! This means I have to go somewhere else to use my own webserver! HELP? ifcfg-eth0 Code: DEVICE=eth0 HWADDR=00:13:21:6a:21:fb NM_CONTROLLED=yes ONBOOT=yes IPADDR=23.XXX.YYY.165 BOOTPROTO=none NETMASK=255.255.255.248 GATEWAY=23.XXX.YYY.161 NETWORK=23.XXX.YYY.160 DNS2=184.108.40.206 TYPE=Ethernet DNS1=220.127.116.11 IPV6INIT=no USERCTL=no Code: [[email protected] Code: [[email protected] How can it be unreachable! I shouldn't even need to have a router to send pings back and forth between two IP's on the same subnet!
