Configure Source and Destination NAT on a Tier-0 Logical Router in Manager Mode

You can configure source and destination NAT on a tier-0 logical router that is running in active-standby mode.

You can also disable SNAT or DNAT for an IP address or a range of addresses. If multiple NAT rules apply to an address, the rule with the highest priority is applied.

SNAT configured on a tier-0 logical router's uplink will process traffic from a tier-1 logical router as well as from another uplink on the tier-0 logical router.
