To create a BIMAP you will need to know the MAC address of the CPE. To obtain this you can 
Telnet to IRIS and issue the "pcpe" command find the cable modem that the end user has, 
attached you will see his CPE Mac address. 

 
Assigning a reserved IP address to the CPE. 
 

Edit the /etc/dhcpd.conf file and add a "host" entry for the MAC address of the CPE with a 
Reserved IP address in the "#CPE Network" subnet 
 

  host user1 { 
        hardware ethernet 00:12:17:4C:9b:21; 
        fixed-address 10.71.0.2 ; 
  } 

 
Save the file and restart the DHCP server using the following commands  
 

# slay -f dhcpd <ENTER> 
# dhcpd en1 <ENTER> 

 
Assigning additional IP addresses to the uplink Interface 
 

From system prompt edit the "netstart.user" file and add the following line 
 

/usr/ucb/ifconfig en2 alias <ip-address> netmask <netmask> 

 
Make sure you put the <ip-address> and <netmask> that you have from your service  
provider. 
 
This command will configure IRIS "en2" or uplink interface with an additional IP address that 
will be used to create a BIMAP. Save the file and exit to system prompt. 
 

Creating a BIMAP between the public IP address and the private IP address 

 
From system prompt edit the startnat file and at the end of the line before the  
"EOF" command 
 

bimap en2 <internal-ip-address>/32 -> <public-ip-address>/32 

 
Replace <internal-ip-address> with the internal IP address that you have reserved in the 
dhcpd.conf file in step 1. Replace <public-ip-address> with the external Ip address that was 
assigned to the en2 port in step 2. Save the file and exit to system prompt. Restart the system to 
make the changes.
