Last week I was helping a customer with installing and configuring VMware vCloud Director 5.1. Things were going pretty smooth until I noticed that we could not get any traffic to get out of the organisation to the external network. The Organisation network was connected to a Edge Gateway but it did not let any traffic through. In vCloud 1.5 this just worked out of the box. It used to have IP Masquerade and NAT enabled per default. After some troubleshooting we figured this was not the case in vCloud 5.1 on Edge Gateways. To enable IP Masquerade and NAT you have to do the following.
- Sub allocate an IP pool to the Edge Gateway
- Create an SNAT rule on the Edge Gateway
