This is mildly off topic since it has more to do with TCP/IP networking
than with CentOS per se. However, at the risk of ruffling a few feathers
I would like some advice on how to resolve the following routing problem:
Given:
dual homed host running CentOS-5.2 with
eth0 = 2xx.yyy.zzz.23
eth1 = 192.168.219.1
and a Cisco gateway at 2xx.1xx.y7y.1 with the following networks:
interface FastEthernet0/1
description connected to EthernetLAN
ip address 10.0.0.1 255.0.0.0 secondary
ip address 172.16.0.1 255.240.0.0 secondary
ip address 192.168.71.1 255.255.255.0 secondary
ip address 192.168.0.1 255.255.0.0 secondary
ip address 2xx.yyy.zzz.1 255.255.255.0
ip access-group 101 in
ip inspect FastEthernet_0_1 in
speed 100
full-duplex
!
router rip
version 2
passive-interface FastEthernet0/0
network 10.0.0.0
network 172.16.0.0
network 192.168.0.0
network 2xx.yyy.zzz.0
no auto-summary
!
ip classless
ip route 0.0.0.0 0.0.0.0 FastEthernet0/0
and with the following routes on the CentOS host:
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.219.0 * 255.255.255.0 U 0 0 0 eth1
2xx.yyy.zzz.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1
default gw-fibrewire 0.0.0.0 UG 0 0 0 eth0
# ip route
192.168.219.0/24 dev eth1 proto kernel scope link src 192.168.219.1
2xx.yyy.zzz.0/24 dev eth0 proto kernel scope link src 2xx.yyy.zzz.23
169.254.0.0/16 dev eth1 scope link
default via 2xx.yyy.zzz.1 dev eth0
The situation is this.
>From the host itself I can ping 192.168.218.102 on 192.168.219.0/24
>From any other host on 2xx.1xx.y7y.0/24 I can ping 192.168.219.1
>From any other host on 2xx.1xx.y7y.0/24 I cannot ping 192.168.219.102
What setup steps on the CentOS host have I overlooked or what
configuration errors have I committed?
