This enhances the existing ability to configure up to 32 additional gateways, which can be selected according to a configurable scheme (first, last used, random) as soon as the primary VPN gateway becomes unreachable.
Now gateways can optionally be collected into groups with equal priority. The highest priority is 0, the lowest 65535. The primary gateway is automatically placed in its own group with a priority of 0. If the primary gateway references a gateway group, this group is added to the level of priority 0, regardless of its configured priority. All gateways in the table of Further remote gateways that do not reference a group name are also added to the group of primary gateways. The selection strategy in the group of primary gateways is defined by the following rules:
- If there are further gateways, the selection strategy is set by the column Begin with gateway in the table of Further remote gateways.
- If there are no further gateways:
- If there is only one primary gateway, then the selection strategy is "first".
- If the primary gateway is a gateway group, the selection strategy of that group is used.
All defined groups are then added to the structure of levels in the order of the gateways from the Further remote gateways table with their priority as stored in the Gateway groups table. The strategy used to select from groups of the same priority is decided by the column Begin with gateway in the Further remote gateways table, and the selection strategy within a group is decided by the column Begin with in the Gateway groups table. The different levels are always used in ascending order of priority beginning with 0.
The configuration is performed under .
