Centos 5.7 Machine Networking Woes


Hello Everyone, and thanks ahead of time for any help .

I am having a interesting issue with a centos machine. It's got me puzzled!

Here is the scenario:

Centos 5.7 Machine with two NIC's.

eth0 == 10.0.10.2 / Gateway 10.0.10.1 / NS 10.0.10.1 (Which is the router we have here locally assigned with a global IP to access the outside world, other machines access the internet just fine).

eth1 == 172.16.0.2 / No Gateway / No NS (this interface only communicates with an iCom ID-RP2C Controller for D-star digital radio).

I can ping anything locally, trying to access the outside world though, is a bit more challenging for the machine. Its default gateway IS 10.0.10.1 - i'm not sure where the problem is. No firewall rules are in place (everything has been flushed just to make sure).

here is my routing table:

[root@gw ~]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.16.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
10.0.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
0.0.0.0 10.0.10.1 0.0.0.0 UG 0 0 0 eth0
[root@gw ~]#


Any help would be appreciated. Thanks!

Forgot to mention, just for S&G I enabled DHCP on the Centos box, it picked up an ip and everything still no outside world...I'm puzzled and ran out of troubleshooting options. I've tried nearly everything.
