I upgraded the ios to 12.4. After the upgrade the interface behavior is a little diffrent. If there is no client connected to one of the fastethernet ports, the e0 interface is down. My problem is, we use this e0 interface for remote administration of the c831 over a vpn connection. So if no device is turned on in the night, I can't reach the router. Is there a solution to keep the interface up or to reach the router otherwise ?
