Chapter 39 Troubleshooting
I can't enter the interface name I want.
The format of interface names other than the Ethernet interface names is very
strict. Each name consists of 2-4 letters (interface type), followed by a number (x,
limited by the maximum number of each type of interface). For example, VLAN
interfaces are vlan0, vlan1, vlan2, ...; and so on.
My rules and settings that apply to a particular interface no longer work.
The interface's IP address may have changed. To avoid this create an IP address
object based on the interface. This way the NXC automatically updates every rule
or setting that uses the object whenever the interface's IP address settings
change. For example, if you change LAN1's IP address, the NXC automatically
updates the corresponding interface-based, LAN1 subnet address object.
Hackers have accessed my WEP-encrypted wireless LAN.
WEP is extremely insecure. Its encryption can be broken by an attacker, using
widely-available software. It is strongly recommended that you use a more
effective security mechanism. Use the strongest security mechanism that all the
wireless devices in your network support. WPA2 or WPA2-PSK is recommended.
The wireless security is not following the re-authentication timer setting I
specified.
If a RADIUS server authenticates wireless stations, the re-authentication timer on
the RADIUS server has priority. Change the RADIUS server's configuration if you
need to use a different re-authentication timer setting.
The NXC is not applying an interface's configured ingress bandwidth limit.
At the time of writing, the NXC does not support ingress bandwidth management.
