Example (Cisco Router): 1 Go to Global Configuration mode. 2 Type ip forward-protocol udp 67 and press Enter. 3 Type ip forward-protocol udp 68 and press Enter. 4 Go to the LAN interface(s) that serves the PXE workstations. 5 Type ip helper-address and press Enter. 6 Type ip helper-address and press Enter. Note: The above IP addresses should be entered without the < or > characters. Configuring Routers 33
