Chapter 13 Interfaces Table 73 Configuration > Network > Interface > Auxiliary (continued) LABEL DESCRIPTION Phone Number Enter the phone number to dial here. You can use 1-20 numbers, commas (,), or plus signs (+). Use a comma to pause during dialing. Use a plus sign to tell the external modem to make an international call. User Name Enter the user name required for authentication. Password Enter the password required for authentication. Retype to confirm Enter the password again to make sure you have not typed it incorrectly. Authentication Select the authentication protocol to use for outgoing calls. Choices Type are: CHAP/PAP - Your ZyWALL accepts either CHAP (Challenge Handshake Authentication Protocol) or PAP (Password Authentication Protocol), as requested by the computer you are dialing. CHAP - Your ZyWALL accepts CHAP only. PAP - Your ZyWALL accepts PAP only. MSCHAP - Your ZyWALL accepts MSCHAP only. Timeout Idle timeout Apply Reset MSCHAP-V2 - Your ZyWALL accepts MSCHAP-V2 only. Type the number of seconds the ZyWALL tries to set up a connection before it stops. Allowed values are 30 - 120. Type the number of seconds the ZyWALL should wait for traffic before it automatically disconnects the connection. Set this field to zero to disable the idle timeout. Allowed values are 0 - 360. Click Apply to save your changes back to the ZyWALL. Click Reset to return the screen to its last-saved settings. 13.9 Virtual Interfaces Use virtual interfaces to tell the ZyWALL where to route packets. Virtual interfaces can also be used in VPN gateways (see Chapter 25 on page 441) and VRRP groups (see Chapter 39 on page 667). Virtual interfaces can be created on top of Ethernet interfaces, VLAN interfaces, or bridge interfaces. Virtual VLAN interfaces recognize and use the same VLAN ID. Otherwise, there is no difference between each type of virtual interface. Network policies (for example, firewall rules) that apply to the underlying interface automatically apply to the virtual interface as well. Like other interfaces, virtual interfaces have an IP address, subnet mask, and gateway used to make routing decisions. However, you have to manually specify the IP address and subnet mask; virtual interfaces cannot be DHCP clients. Like other interfaces, you can restrict bandwidth through virtual interfaces, but you ZyWALL USG 2000 User's Guide 329
