Hello @Steven A. Wunderlin Jr ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

If you want to add an additional network to Azure local network gateway, you can do so by following the below steps:

1. On the Local Network Gateway resource, in the Settings section, select Configuration.
2. Add the IP address space in the Add additional address range box.
3. Select Save to save your settings.

You do not need to delete & recreate the local network gateway. Just make sure that the ranges you specify here do not overlap with ranges of other networks that you want to connect to.
Refer : https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-modify-local-network-gateway-portal#ipaddprefix

As far as the Connection object is concerned, it should work fine after the additional network addition but there are rare cases where it doesn't pick up the new network address space. Only if you face such an issue, you can delete & recreate the connection.

Kindly let us know if the above helps or you need further assistance on this issue.
