This article covers how to make SSL VPN clients to be able to ping workstations on LAN network using hostname when connected to SSL VPN from remote network.

Resolution for SonicOS 7.X

This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOS 7.X firmware.
