Opened: Jan 08, 2021

Severity: 3-Major

Symptoms

On HTTP/2 full-proxy virtual servers, the snatpool command in an iRule is accepted but the source address server-side is not changed.

Impact

Unable to use snatpool (and possibly snat) in iRule to control the server-side source address.

Conditions

1.) Basic HTTP profile and HTTP/2 profile is configured on BIG-IP systems 2.) iRule with snatpool <pool_name>, snat <IP> is configured

Workaround

Configure SNAT under the virtual server configuration, rather than in an iRule.

Fix Information

None
