We have some user PCs have both wired and wireless network connected at the same time.
The 'route print' shows these Windows machines are using the ether0 as the default route to go out, which is correct.
However when we use MS shared folder on these machines, we found all these traffics (port 137 and 445) are sending out via ethe0 using wireless IP as the source.
Dont know why this behavior happened...
Any suggestion is appreciated!
