end-address
set end-address ip_address
Specifies the last address in the DHCP address range.
lease-time
set lease-time lease-time
Specifies the default length for DHCP leases issued by the SHARK™ IAD.
Enter lease time in dd:hh:mm:ss (day/hour/minute/second) format. Default is
1 hour.
option = relay-agent
With the option set to relay-agent the SHARK™ IAD will relay DHCP
address requests from DHCP clients downstream of it and to the DHCP servers
upstream of it in the network. The SHARK™ IAD itself will not assign
addresses. Addresses from an upstream DHCP server will be passed on to the
requesting client.
server-address
set server-address nnn.nnn.nnn.nnn
Specifies the address of the DHCP server on the network.

NAT pinholes let you pass specific types of network through the interfaces on
the SHARK™ IAD when NAT is enabled. NAT pinholes allow you to route
selected types of network traffic, such as FTP requests or HTTP (Web)
connections, to a specific host behind the SHARK™ IAD transparently. To
set up NAT pinholes, you identify the type(s) of traffic you want to redirect by
port number, and you specify the internal host to which each specified type of
traffic should be directed. The following list identifies protocol type and port
number for common TCP/IP protocols:
• FTP (TCP 21)
• Telnet (TCP 23)
• SMTP (TCP 25),
• TFTP (UDP 69)
• SNMP (TCP 161, UDP 161)
• PING (ICMP 8)
Enter the pinhole node as shown:

note on pinholing
Pinhole options will not appear until a pinhole is assigned by assigning a
name to the pinhole being configured. In the above example, the pinhole
node is entered and then the stepper is entered to enter a name of the
pinhole. This pinhole is called 'bob' any name can be used (see 'name'
below). Once a name for the pinhole is assigned the stepper will continue
with the remaining options.
