Symptoms

When subscribers are in a different route-domain from the route-domain used for the prefix in the LSN pool, hairpin connections cannot be established.

Impact

Subscribers cannot make connections to each other using public (translated) addresses.

Conditions

The route-domain used on the Virtual Server is different from the route-domain used on the prefix in the LSN pool.

Workaround

The routes can be configured so the hairpinning takes place on an external router.

Fix Information

None
