In Zettagrid we make all things become simple and faster. Including to configure networks, DHCP, NAT and firewall in virtual data center. Virtual Data Center allows you to configure network services such as DHCP, firewalls, network address translation (NAT), VPN and static routing for your organisation’s network.
On the Networks Tab you have a number of options and configuration items that focus around DHCP, NAT, and Firewall. Below are details on configuration available in the Networks tab for your NSX Advanced Networking Edge.
Network Tab Details
Shows an overview of the selected Network Interface and lets you configure and/or edit the Network as selected from the Drop Down.
- Shows the Type and details as set during the provisioning of the NSX Edge. The first Gateway IP is shown as well as enabled Services, DNS settings and additional IPs
- Clicking on the Edit Button allows you to modify the Uplink Name and give you ability to connect/disconnect the interface.
- By default there are no Internal Interfaces configured and the NSX Edge is not connected to your vDC or is sharing any Interfaces with other vDCs in your Organization. There are 9 Internal Interfaces that can be configured on your NSX Edge.
- To configure an internal Interface, drop down to the vnic number you want to configure and click on the Edit button. You should see the Connected To status as Unconfigured.
- Fill in details relating to the Internal Network
- he Network Name as seen in MyAccount will be different from the VirtualWire/vOrg Network (see below) name presented in vCloud Director.Note: * At the moment Interfaces can not be deleted (Please raise a support request if you require one removed).
- Once You hit Save, Please Wait will appear until the job complete, this can take up to 2 minutes.
- In the background a NSX VirtualWire has been created and linked through to your vDC. You can see that the Connected To details now list a VirtualWire Name that will match a vCloud Director vORG Network. This is the network that you then connect your vCloud VMs and vApps to.
Used to configure DHCP Scopes for the connected Virtual Data Centers. Each DHCP Scope is configured per configured Interface subnet. Once on the Networks Tab, to configure your first DHCP Scope, click on the DHCP Tab and on Add DHCP Pool. (Note that you need to have created at least one Internal Interface). vCloud Director VMs that are connected to the Interface and set for DHCP will now pick up their DHCP settings from the configured pool.
Used to configure Inbound and Outbound Network Address Translation for each configured Interface. Each NAT rule is configured on the selected Interface. NAT services translate source or destination IP addresses and port numbers.
- There are two kinds of NAT rules that you can create:
- Source NAT (SNAT): This kind of rule translates the packet’s source address and, optionally, source IP port to the values you specify.
- Destination NAT (DNAT): This kind of rule translates the packet’s destination address and, optionally, destination IP port to the values you specify.
To create a NAT, you need to know what IP addresses are accessible outside the network and what IP addresses are accessible inside the network.
Used to configure Inbound and Outbound Firewall rules . Firewall rules are Global to the Edge Gateway.
- To create a Firewall Rule, you need to know what IP addresses are accessible outside the network and what IP addresses are accessible inside the network.
- Typically you will use the Primary IP which is the Default Gateway IP shown below.
