CHAPTER 4: Types of Services

WatchGuard Firebox System
Characteristics:
Protocol:  UDP
Client  Port:  ignore
Port Numbers(s): 5001, 5002
CU-SeeMe
CU-SeeMe is a program used to do video conferencing over the Internet. 
For CU-SeeMe to work through the Firebox, you must ensure that you are 
not on a network using outgoing dynamic NAT, and configure the CU-
SeeMe service for both incoming and outgoing access. 
The nature of the CU-SeeMe protocol dictates that you configure this 
service for both incoming and outgoing, regardless of which side is 
originating the connection. The CU-SeeMe icon allows the proper 
combination of ports to enable use of CU-SeeMe versions 2.X and 3.X. 
CU-SeeMe Version 2.X runs on UDP port 7648. Version 3.X, in addition to 
UDP port 7648, runs on UDP port 24032 (for H.323 conferences) and TCP 
port 7648 (video conference directories).
Characteristics
Because CU-SeeMe has a three-step send/receive/send sequence, its 
protocol and port information is grouped in triads.
Port Protocol, UDP; Source Port, port; Destination Port, 7648
Port Protocol, TCP; Source Port, client; Destination Port, 7648
Port Protocol, UDP; Source Port, ignore; Destination Port, 24032
DHCP-Server/Client
Dynamic Host Configuration Protocol (DHCP) provides a means of 
dynamically allocating IP addresses to devices on a network.
Characteristics
Service Name: DHCP-Server or DHCP-Client
Protocol:  UDP
Client  Port:  client
Port Number: Server: 68; Client: 67
