Edit the Suballocated IP Pools on an Edge Gateway in VMware Cloud Director

In VMware Cloud Director, you can suballocate multiple static IP pools from the available IP pools of an external network on an edge gateway.

Note: Allocating IP addresses to an edge gateway through sub-allocation is a process where the provider assigns ownership of IP addresses to the gateway. VMware Cloud Director automatically configures the appropriate gateway interface with the secondary addresses during the sub-allocation process, which can cause IP address conflicts if any of the IP addresses are used outside of VMware Cloud Director.

Procedure

1. From the top navigation bar, select Resources and click Cloud Resources.
2. In the left panel, click Edge Gateways, and click the name of the target edge gateway.
3. Click the External Networks > Sub-allocated IP pools tab.
   You can see the current suballocated IP pools for each external network on this edge gateway.
4. Click the radio button next to the name of an external network, and click Edit.
   You can see the available IP pools for this external network, and the current suballocated IP pools if configured.
5. Edit the suballocated IP pools for this external network, and click Save.
   You can add, modify, and remove IP addresses and ranges from the ranges of the available IP pools.

Results

The system combines overlapping IP ranges.
