Adding NAT Rules to Support Hairpin NAT

When a client and server access the Cloud Edge gateway from the same LAN interface, the client cannot access this server by domain name. To support this scenario, add both a source NAT rule and a destination NAT rule to this LAN interface. Use the following procedure to perform this configuration.

  1. Go to Gateways > (Selected Gateway) > NETWORK > NAT > Add.
  2. Select Source for NAT type.
  3. Configure the client and server linked LAN interface for Egress interface.
  4. Select Egress interface IP address for Source IP translation.
  5. Click Save.
  6. Go to Gateways > (Selected Gateway) > NETWORK > NAT > Add.
  7. Select Destination for NAT type.
  8. Configure the client and server linked LAN interface for Ingress interface.
  9. Select Virtual IP for Destination IP translation.
  10. Configure External IP address/range with the server Internet IP address registered to DNS server.
  11. Configure Translated IP address/range with the server's local IP address.
  12. Click Save.
  13. Verify that the new rules are added to the list of NAT rules.
