6.9.1 IP Address Assignment for Remote Networking
An SCS handles incoming calls from a series of remote node users. Two of these users, Bob and Frank, have
special IP address requirements.
The SCS must be configured to do the following:
◆ Assign the same IP address to Bob each time he logs in.
◆ Permit Frank to select his own IP address.
Note: In general, allowing user-selected IP addresses is not recommended. It poses
some security risks and could result in duplicate IP addresses.
◆ Dynamically assign IP addresses to the remaining remote node users from an IP address pool. Only
five SCS ports have been configured to accept incoming calls, therefore, only five IP addresses must
be included in the pool.
Bob will use site bob when he logs into the SCS. At authentication time, he will be prompted for the site’s
local password, badger. He will be assigned IP address 192.0.1.108.
Figure 6-49: Configuring Site bob
When Frank logs into the SCS, he will use site frank, which requires that he enter the password wallaby.
No remote IP address is defined for this site, therefore, Frank may use any IP address he wishes.
Figure 6-50: Configuring Site frank
To create the IP address pool, use the following command:
Figure 6-51: Creating IP Address Pool
All incoming callers that do not specify a particular site (such as bob or frank) will use the default site for
the connection. To require that default site users use an IP address from the pool, use the Define Site
Default IP Remoteaddress command.
