Configuring the WAN
STEP 4
Cisco ISA500 Series Integrated Security Appliance Administrator Guide
•
WAN Name: The name of the primary WAN (WAN1).
•
IP Address Assignment: Choose the network addressing mode for the
primary WAN depending on the requirements of your ISP. The security
appliance supports DHCPC, Static IP, PPPoE, PPTP, and L2TP. For complete
details to configure the network addressing mode, see
Network Addressing Mode, page
•
DNS Server Source: DNS servers map Internet domain names (example:
www.cisco.com) to IP addresses. You can get DNS server addresses
automatically from your ISP or use ISP-specified addresses.
-
Get Dynamically from ISP: Choose this option if you have not been
assigned a static DNS IP address.
-
Use These DNS Servers: Choose this option if your ISP assigned a static
DNS IP address. Also enter the addresses for the DNS1 and DNS2 fields.
•
MAC Address Source: Specify the MAC address for the primary WAN.
Typically, you can use the unique 48-bit local Ethernet address of the
security appliance as your MAC address source.
-
Use Default MAC Address: Choose this option to use the default MAC
address.
-
Use the Following MAC Address: If your ISP requires MAC
authentication and another MAC address has been previously registered
with your ISP, choose this option and enter the MAC address that your ISP
requires for this connection.
•
MAC Address: Enter the MAC Address in the format xx:xx:xx:xx:xx:xx where
x is a number from 0 to 9 (inclusive) or an alphabetical letter between A and
F (inclusive), for example, 01:23:45:67:89:ab.
•
Zone: The primary WAN must be mapped to an untrusted zone. The WAN
zone is the default unstrusted zone. Click Create Zone to create other
untrusted zones. See
In the IPv6 tab, specify the IPv6 addressing if you enable the IPv4/IPv6 mode.
•
IP Address Assignment: Choose Static IP if your ISP assigned a fixed
(static or permanent) IP address. If you were not assigned a static IP address,
choose SLAAC. By default, your security appliance is configured to be a
DHCPv6 client of the ISP, with stateless address auto-configuration
(SLAAC).
