F6: Can't connect to Internet with Direct Connection (no router)

[Straker]

Hi all.

I am installing a Fedora Core 6 server which needs to directly connect to the internet. I have also disabled the firewall (due to the purpose of the server).

Here is the deal. I am unable to connect to the internet (even outgoing) so I believe that I have a routing issue or something. I have a surfboard cable modem that is provisioned with 5 static IPs and currently run several servers behind routers (each with a static IP). This Fedora box is the first one directly connected.

My provisioned IPs are xx.yy.116.114 - xx.yy.116.118, and the gateway for these are xx.yy.116.113. I want to use xx.yy.116.115 for the Fedora box.

BTW, I am able to connect to the Fedora server (using xx.yy.116.115) as long as I am on another box on the network (e.g. xx.yy.116.118), but not from anywhere else.

There is only one network card (eth0) on the Fedora server:

Here is my relevant files:

/etc/hosts:

PHP Code:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain   localhost
::1     localhost6.localdomain  localhost6 


/etc/sysconfig/network:

PHP Code:

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=fedora.mydomain.com 


/etc/sysconfig/network-scripts/ifcfg-eth0:

PHP Code:

# nVidia Corporation MCP51 Ethernet Controller
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:16:EC:1C:20:2E
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
NETMASK=255.255.255.248
IPADDR=xx.yy.116.115
GATEWAY=xx.yy.116.113 


/etc/resolv.conf:

PHP Code:

; generated by /sbin/dhclient-script
nameserver 67.21.15.2
nameserver 67.21.15.18
nameserver 66.239.255.16 


route -n:

PHP Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
xx.yy.116.112   0.0.0.0         255.255.255.248 U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth0
0.0.0.0         xx.yy.116.113   0.0.0.0         UG    0      0        0 eth0 


The route -n output is what I am confused about. Why is xx.yy.116.112 showing up as a destination? I have no idea what this IP address is. Should the box itself xx.yy.116.115 show up as a destination?

Any help is much appreciated.

It turned out to be a hardware driver issue. I was using the onboard nvidia ethernet port and the driver that comes with Fedora 6 was invalid. I downloaded the updated driver from nvidia and that fixed it. The confusion is that the driver works on a Lan environment but not on the internet.

Stumbled across the solution while trying to fix my invisible mouse cursor problem. The following thread solved both my problems.

BTW, the Fedora 5 driver works with Fedora 6.

Cheers.
