I do have another gateway at 10.0.254.1, it is a Linksys router that all the provate stuff plugs into, and that Linksys plugs directly into our modem.

Hi All,
I have 2 NICS in this system. CentOS 6.4
eth0 is the virtual IP from PFSense mapping connected to the router,
works
fine.
eth1 is a second NIC that I have assigned a private IP to and connected
it
to a switch on the private network. I have many other private devices,
so I
know this setup works.
When I connect the cable to the switch and bring up eth1 the system basically stops taking requests. I can no longer SSH in, Websites stop responding, etc. If I walk over to the server and take down eth1, everything works fine.
Here is eth0: DEVICE=eth0 HWADDR=00:1b:21:cd:80:bf TYPE=Ethernet UUID=68a95912-3915-4b1a-9080-eb2017330153 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPADDR=192.168.1.27 NETMASK=255.255.255.0 DNS2=8.8.4.4 GATEWAY=192.168.1.1 DNS1=8.8.8.8 IPV6INIT=no USERCTL=no
Here is eth1: DEVICE=eth1 HWADDR=00:0a:cd:17:07:7e TYPE=Ethernet UUID=b3851363-ae9e-4066-8993-caed07b9945b ONBOOT=no NM_CONTROLLED=yes BOOTPROTO=none IPADDR=10.0.254.11 NETMASK=255.255.255.0 GATEWAY=10.0.254.1 DNS1=8.8.8.8 DNS2=8.8.4.4 IPV6INIT=no USERCTL=no
I have never experienced this before.
Remove the GATEWAY line from eth1, unless you have another router (with its own access to the Internet) at 10.0.254.1. If eth0 points at your upstream, then this is unlikely.
