Support names as well as IP addresses for local gateway on site-to-site VPN
Today you only allow IP addresses to be specified as the local gateway endpoint for a site-to-site VPN. Customers who receive their public IP via DHCP would greatly benefit if this config parameter could also take a DNS name that the Azure gateway infrastructure would resolve to the current IP (and if there are connectivity issues, re-resolve as the IP may have changed).
Unfortunately, static IP address is a requirement on the Azure VPN. Switching to DNS name based IPsec/IKE is currently not possible.
