You can terminate the Ping exchange at any time by pressing Ctrl-C. 
Configuring system-level routing policies
Depending on the requirements of your network environment, you need to configure 
system-global routing policies in addition to the LAN interface. Services available for the 
MAX include:
Dynamic IP addressing
Boot Protocol (BOOTP) requests 
Name resolution services: Domain Name System (DNS) and Windows Internet Name 
Service (WINS)
Dynamic Host Configuration Protocol (DHCP)
Network Address Translation (NAT)
Additional system-level services include system time, Telnet password, shared Connection 
profiles, suppression of dial-out route advertisement in redundant configurations when a trunk 
fails, UDP checksums, and suppression of host route advertisements.
For detailed information about each parameter in the following sections, see the MAX 
Reference.
Dynamic IP addressing for dial-in hosts
For dial-in PPP clients not running as IP routers, the MAX can assign each connection to a 
local IP address on a first-come, first-served basis. After the connection is terminated, the 
address that was assigned to that connection is returned to the pool for reassignment to another 
connection. 
Enabling dynamic address assignment
To enable the MAX for dynamic address assignment, you set the Assign Address parameter in 
the Answer profile to Yes. 
Specifying address pools
In addition, to enable dynamic addressing, you must set the address pool parameters in the 
Ethernet > Mod Config > WAN Options menu. You can configure a MAX unit to contain as 
many as 10 address pools of as many as 254 addresses for dynamic assignment, as described in 
the following sections.
Set the Pool#N Start parameter to specify the first address in a block of contiguous addresses 
on the local network or subnet. Set the Pool#N Count parameter to specify how many 
addresses are in the pool (up to 254). 
Addresses in a pool do not accept a subnet mask, because they are advertised as host routes. If 
you allocate IP addresses on a separate IP network or subnet, make sure you inform other IP 
routers about the route to that network or subnet, either by statically configuring those routes 
or by configuring the unit to dynamically send updates.
