Description linux user 2005-03-04 06:09:54 EST
Description of problem:
When both wired and wireless networks have static IP, and both IP
networks are the same number, and wired is not connected, system
attempts to route all gateway traffic via the wired adapter (eth0). If
wired adapter is down (ifdown eth0) then no external networks are
reachable -- the wireless connection is then useless except for local
traffic, even though the static IP config for the wireless adapter
clearly shows the default gateway listed correctly.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:

1. Starting with a fresh FC3 install on a laptop with centrino
wireless, configure the wired network card eth0 with a static IP
address, DNS, and gateway.

2. Verify connection to internet on wired interface (download wireless
drivers/firmware if needed). Then disconnect the wire and reboot.

3. Then install wireless centrino drivers and configure that interface
(eth1) as a static address on the same network (e.g. if the IP for
eth0 was then make this one Enter the
same gateway and DNS info as for the wired interface. Activate eth1,
reboot if necessary.

4. At this point you will not be able to ping the router unless eth0
is down.  Entering ifdown eth0 and then a ping will respond, but now
there is no route to other networks.
Actual results:  Can connect to all local systems, no routing through

Expected results: Expected normal routing.

Additional info: Type "route" in a terminal and you will see there is
no route to other networks.

Sorry, my 1st submit was to NetworkManager, should have been listed as

Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.

Thank you!

Fedora Core 3 is not maintained anymore.

Setting status to "INSUFFICIENT_DATA". If you can reproduce this bug in the
current Fedora release please reopen this bug and assign it to the corresponding
Fedora version.
