• 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.
• The names of virtual interfaces are derived from the interfaces on which they
are created. For example, virtual interfaces created on Ethernet interface ge1
are called ge1:1, ge1:2, and so on. Virtual interfaces created on VLAN interface
vlan2 are called vlan2:1, vlan2:2, and so on. You cannot specify the number
after the colon(:) in the Web Configurator; it is a sequential number. You can
specify the number after the colon if you use the CLI to set up a virtual
interface.
I cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface
on an Ethernet interface.
You cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN
interface if the underlying interface is a member of a bridge. You also cannot add
an Ethernet interface or VLAN interface to a bridge if the member interface has a
virtual interface or PPP interface on top of it.
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 ZyWALL 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 ZyWALL automatically
updates the corresponding interface-based, LAN1 subnet address object.
I cannot set up a PPP interface.
You have to set up an ISP account before you create a PPPoE or PPTP interface.
The data rates through my cellular connection are no-where near the rates I
expected.
The actual cellular data rate you obtain varies depending on the cellular device
you use, the signal strength to the service provider’s base station, and so on.
