Hello,

After some minutes of inactivity, or generally about 5-10 minutes, link
seems down.
Ethernet interface on soekris board (net4501) is not avaiable : it
doesn't respond to ping and clients behind nat can't access to internet.
Problem is resolved in 2 methods :
1) Power off system an power on after some seconds
2) Plug out ethernet cable and plugin itself after some seconds

Have you got any idea for this problem?
Is a monowall problem?
