This is not a good idea. By having 2 different interfaces on the same subnet you are creating 2 different routes to this subnet. You should definitely only have one default gateway (unless you are doing split-routing, or something). However, I am surprised that they both break, as I would have expected one of them to continue working. If you must have both interfaces on the same subnet then I would look into bonding (using the "ifenslave" package), or bridging (using the "bridge-utils" package). Your choice would depend on what your objective is. Hope this helps, -- George Borisov DXSolutions Ltd
