For instance, if the on-premises BGP IP address is 10.30.0.133 and there is an **Ingress NAT Rule** that translates 10.30.0.0/24 to 172.30.0.0/24, the VPN site's **Link Connection BGP Address** must be configured to be the translated address (172.30.0.133).

* In Dynamic NAT, on-premises BGP peer IP can't be part of the pre-NAT address range (**Internal Mapping**) as IP and port translations aren't fixed. If there is a need to translate the on-premises BGP peering IP, please create a separate **Static NAT Rule** that translates BGP Peering IP address only.

For instance, if the on-premises network has an address space of 10.0.0.0/24 with an on-premises BGP peer IP of 10.0.0.1 and there is an **Ingress Dynamic NAT Rule** to translate 10.0.0.0/24 to 192.198.0.0/32, a separate **Ingress Static NAT Rule** translating 10.0.0.1/32 to 192.168.0.02/32 is required and the corresponding VPN site's **Link Connection BGP address** must be updated to the NAT-translated address (part of the External Mapping).
