DHCP Server
The existing DHCP Server can be on either side of the firewall, according
to the site administrator’s preference. The DHCP server is optional if the
wireless handsets and WLAN IP Telephony Manager 2245 are statically
configured.
DHCP options
If you use a DHCP Server, configure the following options:
•
DHCP Option 3—the Default Gateway
• DHCP Option 7—the Syslog Server
•
DHCP Option 42—the Time Server
• DHCP Option 60—the Class Identifier
• DHCP Option 66—the IP address of the TFTP Server
• DHCP Option 151—the IP address of the WLAN IP Telephony
Manager 2245
• DHCP Option 152—the IP address for the optional WLAN Application
Gateway 2246
For more information, see “DHCP server options” (page 177).
TFTP Server
A TFTP Server is required in an IP Telephony system to distribute
software to the wireless handsets and WLAN IP Telephony Manager 2245.
It can reside on a different subnet than the Call Server and APs. The
TFTP Server can be located on either side of the firewall.
Firewall
The firewall is an optional element that is often used to separate the
wireless and wired domains.
