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.
When you configure the SSLVPN profile, the firewall will automatically create an access rule for the LAN zone to permit the traffic from the SSLVPN | Go to Policy | Rules and Policies | Access Rules and select SSLVPN to LAN
If you try to reach the destination host, doing a packet monitor you can see the traffic dropped due to "Policy Dropped".
To allow the traffic to pass through the firewall, you need to create the same access rule from the other zone (i.e. the zone of the secondary bridged I/F) allowing the traffic from the SSLVPN | Go to Policy | Rules and Policies | Access Rules and select SSLVPN to custom_zone.
