Command-Line Interface
Create an address object for the public IPv4 addresses:
gw-world:/> add Address IP4Address wwwsrv_pub
Address=195.55.66.77-195.55.66.81
Now, create another object for the base of the web server IP addresses:
gw-world:/> add Address IP4Address wwwsrv_priv_base Address=10.10.10.5
Publish the public IPv4 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 IPv4 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
SourceNetwork=all-nets
DestinationInterface=wan
DestinationNetwork=wwwsrv_pub
SATTranslateToIP=wwwsrv_priv_base
SATTranslate=DestinationIP
Finally, create an associated Allow Rule:
gw-world:/main> add IPRule Action=Allow
Service=http
SourceInterface=any
SourceNetwork=all-nets
DestinationInterface=wan
DestinationNetwork=wwwsrv_pub
Web Interface
Create an address object for the public IPv4 address:
1. Go to: Objects > Address Book > Add > IP4 Address
2. Specify a suitable name for the object, for example wwwsrv_pub
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 > IP4 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:
