Configuring Mulitple Static IP Addresses

If you did not receive a subnet mask from your ISP, but were provided with a number of addresses has been, 
you can look up the associated subnet mask in the  table below. Because this information may have been 
identified in a number of different ways, it has  been presented here in a number of different ways.
Step 2: Allocate Public IP Addresses to the LAN Clients
This step requires that all network devices that you  wish to configure with a broadband IP...

For devices using the Public Network addresses, simply configure the device to use the IP address (subnet 
mask and default gateway) as assigned by the ISP . The gateway will automatically detect the usage of a 
broadband IP address on the LAN network and correctly ro ute the return traffic to the appropriate LAN 
device. Once a broadband IP address has been detected by  the gateway as being statically coded on the 
device, its entr y in the Address Allo...

Sample Configuration
In the sample network below, the customer has subscribed to ser vice with an 8 IP address subnet (i.e., 5 
usable broadband IP addresses). The customer wants to  host dedicated VPN and web servers in addition to 
having PCs with private IP addresses. The subnet  assigned to the customer is 208.35.230.192/29. The 
sample network is shown in Figure *.

First, configure the gateway to suppor t “Public Network” static IP addressing using the ser vice provider 
assigned IP addresses of 208.35.206.198 for the  gateway and a subnet mask of 255.255.255.248 as 
shown in Figure xxx. Click 
SAVE to ensure the changes are saved.

Second, assign static IP addresses to the Network  Ser vers from the available. This can be done by hard 
coding these on the network interface for t hese ser vers or via the gateway...

Edit the addresses assigned to each device as shown below. Assign an available static IP address to each 
ser ver, selecting the “DHCP Fixed” option from the lis t box next to each ser ver name. For this example, 
select the following options:
Click 
SAVE after making your selections in order  to ensure the addresses are properly assigned.
After this step, restar t each server so that  it is issued the desired static IP address.
Finally, configure the gateway...

In the case of the Web Ser ver, the “hosted application” feature of the 3700HGV-B will be used. This feature 
provides a quick and easy way to allow specific types  of unsolicited traffic through the 3700HGV-B firewall. 
For the web ser ver, this includes traffic on TCP port 80 (http).
Select the computer to which you would like to have a ll data sent. In this example, the computer selected is 
VPNSRV.
Select 
Allow all applications and click DONE. Doing so...

To allow all traffic for the web ser ver, configure the gateway to allow the specific type of the associated 
inbound por ts to flow to the ser ver. In this example, the computer WEBSRV is selected as the destination 
for the web ser ver traffic.
Select the 
Allow individual application(s) option.
Select the appropriate application fr om the application list, click the 
ADD buttton, and then click the DONE 
button. In this example, the application type is “Web...
