Opened: Sep 25, 2020
Severity: 3-Major

Symptoms

A snat-translation address with ARP enabled responds to ARP requests but not ICMP ECHO requests.

Impact

Application traffic should not be impacted, as external hosts trying to resolve the snat-translation and return traffic to it should still be able to do so; however, ping is an important network troubleshooting tool, and not being able to ping the address may create confusion.

Conditions

A snat-translation address is configured with ARP enabled.

Workaround

None.

Fix Information

A snat-translation now correctly responds to both ARP requests and ICMP ECHO requests.
