Strange IPv4 Routing Issue on KVM Linux Node

Posts: 4
I have primary /24 routed to a Centos 6 VPS node, KVM based system. I needed to add secondary /26 subnet specific to a VM for a client. I created the ifcfg-eth0-range0 file.
[root@kvm1 network-scripts]# cat ifcfg-eth0-range1 IPADDR_START=xxx.244.42.194 IPADDR_END=xxx.244.42.254 CLONENUM_START=0
Weird thing is, out of all 64 IPs, I can ping gateway fine and random IPs in between like 200, 196, etc but seems like the other half are getting "expired in transit" error oddly.
[root@kvm1 network-scripts]# cat ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=static IPADDR=xxx.xxx.200.2 NETMASK=255.255.255.0 GATEWAY=xxx.xxx.200.1 ONBOOT=yes [root@kvm1 network-scripts]# cat ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=static IPADDR=xxx.xxx.200.2 NETMASK=255.255.255.0 GATEWAY=xxx.xxx.200.1 ONBOOT=yes [root@kvm1 network-scripts]# cat ifcfg-eth0 DEVICE=eth0 HWADDR=00:25:90:A1:76:06 TYPE=Ethernet UUID=187bd7f3-7ee1-4706-9489-1097cee44b3a ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static BRIDGE=br0 [root@kvm1 network-scripts]# cat ifcfg-eth0-range0 IPADDR_START=xxx.xxx.200.2 IPADDR_END=xxx.xxx.200.128 CLONENUM_START=0
Ran service network restart after and still can't ping all IPs, just random in between ones out of the /26.
