HP VCX Software Surroundings, Save, Create, Cancel, Delete Row, Interface/VLAN

Chapter 4. Network Configuration

For computers in an IP range that you want to give a network name, enter the last IP address in the range. The IP address in Upper Limit must be at least as high as the one in Lower Limit. If you use a subgroup, leave this field empty.

IP Address

The IP address of the object you entered in the DNS Name Or IP Address field is displayed here. This field is not updated until you click on Look up all IP addresses again or make changes in the DNS Name Or IP Address field.

Interface/VLAN

Here, you can select an interface or a VLAN to restrict the IP range.

If the interface ’-’ is chosen, the group will consist of all IP addresses in the interval between Lower limit and Upper limit, regardless of what interface they are connected to. By selecting an interface or a VLAN, you constrain the group to consist only of the IP addresses in the interval that really are connected to the selected interface/VLAN.

For example, if 10.20.0.0 - 10.20.0.255 are IP addresses behind the interface DMZ-1 and the lower and upper limits are 10.10.10.20 and 255.255.255.255 respectively, choosing DMZ-1 as Interface will cause the group to consist of the IP addresses 10.20.0.0 - 10.20.0.255, being the IP addresses in the interval actually connected to the selected interface.

If you have selected a subgroup, the Interface/VLAN should be ’-’.

Delete Row

If you select this box, the row is deleted when you click on Add new rows, Save, or Look up all IP addresses again.

Create

Enter the number of new groups and rows you want to add to the table, and then click on Create.

Save

Saves the Networks and Computers configuration to the preliminary configuration.

Cancel

Clears and resets all fields in new rows and reset changes in old rows.

Surroundings

Settings on the Surroundings page are only required when the Telecommuting Module has been made the DMZ type.

The Telecommuting Module must know what the networks around it looks like. On this page, you list all networks which the Telecommuting Module should serve and which are not reached through the default gateway of the firewall .

All computers that can reach each other without having to go through the firewall connected to the Telecommuting Module should be grouped in one network. When you are finished, there should be one line for each of your firewall’s network connections (not counting the default gateway).

One effect of this is that traffic between two users on different networks, or between one of the listed networks and a network not listed here, is NAT:ed.

Another effect is that for connections between two users on the same network, or on networks where neither is listed in Surroundings, no ports for RTP sessions will be opened, since the Telecommuting Module assumes that they are both on the same side of the firewall.
