Hi guys,
I have some OpenVZ nodes.
The server main IP (eth0) is 200.44.32.42, the allocation is 200.44.32.40/29 - 200.44.32.41 being the GATEWAY.
The ADDITIONAL IP allocation is 200.44.32.96/28, 200.44.32.97 being the GATEWAY.
Now, if I be specific on /etc/sysconfig/network-scripts/ifcfg-eth0 and declare everything like so:
DEVICE=eth0
BOOTPROTO=none
BROADCAST=10.20.47.255
HWADDR=
IPADDR=10.20.42.198
NETMASK=255.255.248.0
NETWORK=10.20.40.0
ONBOOT=yes
GATEWAY=10.20.40.1
TYPE=Ethernet
Please ignore all the above IPs config.
Now, using that VE nodes on the 200.44.32.96/28 range are unpingable. How can I fix that?
Please take note that I remove all settings from ifcfg, and leave IPADDR and GATEWAY, the internet can ping the nodes. But within the 200.44.32.0/24 no-one can ping the nodes on the 200.44.32.96/28 range ( Which is my problem, that I came here to solve).
Here's the VE

You have new mail in /var/spool/mail/root
root@NM [~]# iptables -t nat -L && iptables -t filter -L && iptables -t mangle -L
iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
