And you have "GATEWAY=" in each of the ifcfg-eth# files right? If you do, then the problem is that when you bring up eth0, the system sets up the default route to point at the GATEWAY= entry in ifcfg-eth0. Then, when the system brings up eth2, it sets the default route to point at the GATEWAY= entry in ifcfg-eth2. The end result is that the default route for the system is set to the gateway for eth2. If you want the default route to be different from the gateway for the last interface, you need to set the gateway in /etc/sysconfig/network. Then, set up a separate init script that configures static routes appropriately for each interface.
We've seen the same problem on RHEL3, RHEL4, and RHEL5 and this was the only way we have been able to get around it. -Maarten Broekman -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, July 24, 2008 12:02 PM To: [email protected] Subject: RE: [rhelv5-list] problem with multiple interfaces not a router Ok to stay consistent: Eth0 120.207.7.245 Eth2 120.207.17.22 I am testing from: 120.207.6.11 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Watts Sent: Thursday, July 24, 2008 11:58 AM To: Red Hat Enterprise Linux 5 (Tikanga) discussion mailing-list Subject: Re: [rhelv5-list] problem with multiple interfaces not a router On Thursday 24 July 2008 16:54:55 [EMAIL PROTECTED] wrote: > This was not the case.
