FAQ

I don't know how to create the NAT rule in vCloud Director tenant portal (edge > edge service gateway).

(:Last updated)

Edge - edge service gateway is the virtual network appliance (Layer 3 network) working in the organization virtual datacenter provided as "managed v platform Powered by VMware" menu.
Customer can connect the external network/network to the edge - edge service gateway.
In the edge - edge service gateway, the network functions such as firewall / DHCP / NAT/routing / loadbalancer / VPN are available.
By using NAT in the edge - edge service gateway, Customer can change the "destination and source IP address" and the "destination and source port" of the IP packets which go through the edge - edge service gateway.

#1) If Customer uses the firewall and NAT together, as the process order, the IP packets are dealt with by firewall at first and then by NAT.
If Customer needs to change the IP address and port by using NAT, Customer needs to configure the firewall rule to accept the IP packet which "destination and source IP address" and "destination and source port" are not yet translated by NAT.
