created a cellular interface but cannot connect through it.
Make sure you have a compatible 3G device installed or connected. See Chapter
57 on page 915 for details.
Make sure you have the cellular interface enabled.
Make sure the cellular interface has the correct user name, password, and PIN
code configured with the correct casing.
If the ZyWALL has multiple WAN interfaces, make sure their IP addresses are on
different subnets.
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.
I cannot configure a particular VLAN interface on top of an Ethernet interface even
though I have it configured it on top of another Ethernet interface.
Each VLAN interface is created on top of only one Ethernet interface.
I cannot get the auxiliary port to connect to my phone line.
You have to connect an external modem to the ZyWALL’s auxiliary port to use the
auxiliary interface.
