To create firewall and NAT rules, you can use preconfigured application port profiles and custom application port profiles.
Application port profiles include a combination of a protocol and a port, or a group of ports, that is used for firewall and NAT services on the edge gateway. In addition to the default port profiles that are preconfigured for NSX-T Data Center, you can create custom application port profiles.
When you create a custom application port profile on an edge gateway, it becomes visible to all the other NSX-T Data Center edge gateways that are in the same organization VDC.
- In the top navigation bar, click Networking and click the Edge Gateways tab.
- Click the edge gateway.
- Under Security, click Application Port Profiles.
- In the Custom Applications section, click New.
- Enter a name and, optionally, a description for the application port profile.
- Select a protocol from the drop-down menu.
- Enter a port, or a range of ports, separated by a comma, and click Save.
