Static IP Settings revert to DHCP within 10 seconds

Switched from Ubuntu 7.10 to FC8-RC3 today and wanted to setup a static IP of 192.168.1.210, since my router is already programmed to forward incoming SSH connections to this address.

Using system-config-network / System -> Administration -> Network GUI, I:
* selected Statically set IP address
ADDR: 192.168.1.210
SNM: 255.255.255.0
GW: 192.168.1.1

Press ok, deactivate, activate

With the terminal window open, /sbin/ifconfig shows the desired new IP address for the first few seconds. Then, when the "Wired Network Connection" icon appears in the top right corner of the screen, I learn that my IP address is back on the DHCP-assigned 192.168.1.5.

This is from my /etc/sysconfig/network-scripts/ifcfg-eth0 file:

# Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.1.210
GATEWAY=192.168.1.1
TYPE=Ethernet
USERCTL=yes
IPV6INIT=no
PEERDNS=yes
HWADDR=00:15:f2:92:05:63

Notes:
-There are no other devices with the same IP on my network
-I have rebooted my router
-I have un-bound the mac ID in the settings and tried again with the same result
-/etc/init.d/network restart was run after every change, /sbin/ifconfig confirms the settings change, but then 10 seconds later it reverts back to the undesired address
-alternative static IP's have been tested with the same result, ie: 192.168.1.211, 209

Any advice would be appreciated. Thanks,

Jeremy

Just guessing but do you have NetworkManager running? You might want to disable it.
