7.3.2. Translation of Multiple IP
Addresses (M:N)
gw-world:/> add Address IP4Address wwwsrv_priv_base Address=10.10.10.5
Publish the public IP addresses on the wan interface using ARP publish. One ARP item is needed for every IP
address:
gw-world:/> add ARP Interface=wan IP=195.55.66.77 mode=Publish
Repeat this for all the five public IP addresses.
Next, change the current category to be the main IP rule set:
gw-world:/> cc IPRuleSet main
Next, create a SAT rule for the translation:
gw-world:/main> add IPRule Action=SAT Service=http SourceInterface=any
Finally, create an associated Allow Rule:
gw-world:/main> add IPRule Action=Allow Service=http SourceInterface=any

3. Enter 195.55.66.77 - 195.55.66.77.81 as the IP Address
4. Click OK
Now, create another address object for the base of the web server IP addresses:
1. Go to Objects > Address Book > Add > IP address
2. Specify a suitable name for the object, for example wwwsrv_priv_base
3. Enter 10.10.10.5 as the IP Address
4. Click OK
Publish the public addresses on the wan interface using ARP publish. One ARP item is needed for every IP
address:
1. Go to Interfaces > ARP > Add > ARP
2. Now enter:
• Mode: Publish
• Interface: wan
• IP Address: 195.55.66.77
3. Click OK and repeat for all 5 public IP addresses
Create a SAT rule for the translation:
1. Go to Rules > IP Rules > Add > IPRule
2. Specify a suitable name for the rule, for example SAT_HTTP_To_DMZ
3. Now enter:
• Action: SAT
SourceNetwork=all-nets DestinationInterface=wan
DestinationNetwork=wwwsrv_pub SATTranslateToIP=wwwsrv_priv_base
SATTranslate=DestinationIP
SourceNetwork=all-nets DestinationInterface=wan
DestinationNetwork=wwwsrv_pub
