Re: [CentOS] OT: Setting a CentOS to gateway a private IP address
I have discovered quagga and installed it on the dual-homed CentOS-5.2 box that I am attempting to configure as a router. Given my previous requirements and configuration: dual-homed host running CentOS-5.2 with eth0 = 2xx.yyy.zzz.23 eth1 = 192.168.219.1 and given that our Cisco 2605 uses ripv2 I infer that my /etc/quagga/ripd.conf file needs to look something like this: hostname myhost.domain.tld password somepassword router rip network eth0 --- is this correct? network 192.168.219.0/24 Can anyone provide me with some further guidance on this together with any recommendations respecting zebra.conf?

[CentOS] OT: Setting a CentOS to gateway a private IP address
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 RefUse Iface 192.168.219.0 * 255.255.255.0 U 0 00 eth1 2xx.yyy.zzz.0 * 255.255.255.0 U 0 00 eth0 169.254.0.0 * 255.255.0.0 U 0 00 eth1 default gw-fibrewire 0.0.0.0 UG0 00 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?

Seems like your trying to route through the linux box? Have you enabled ip forwarding and checked your iptables ruleset to make sure that either the default policy is ACCEPT or that you have specific rules in there that allow forwarding?

To be sure that the firewall was not the source of trouble I temporarily turned it off and observed no change in behaviour from that previously reported. Another correspondent pointed out that I may need to run routed to propagate the routing information from the host to the network. Or apply static routes on the other network - or NAT to the connecting interface address on the way out. -- Les Mikesell [EMAIL PROTECTED] ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
