Managing Service Gateways

A service gateway forwards inbound TCP connections from a port on the hypervisor to a port on a virtual machine on the NAT network. Every address the hypervisor holds accepts the forwarded traffic. You manage service gateways from the Service Gateways tab of the hypervisor’s detail page.

Add a Service Gateway

1. On the Service Gateways tab, select Add Service Gateway.

2. Under Settings, enter a Name.

3. Under Traffic Mapping, fill in the mapping row:

   Field	Set to	Example
   Target	The virtual machine to forward to. Only machines with an interface on the NAT network are listed.	web-01
   Type	TCP, the only option	TCP
   Source	The port on the hypervisor that accepts the connection, between 1 and 1024	443
   Destination	The port on the virtual machine	8443

4. Select Add Mapping for each further port to forward, and the trash icon to remove a row.

5. Select Create.

A source port can be used by one mapping on the hypervisor. The form rejects a port already taken by another service gateway.

A service gateway cannot be edited. To change a mapping, delete the gateway and add it again.

Delete a Service Gateway

Deleting a gateway closes every connection open through it.
