The Server Access policy decides who can reach which Secure Server (or child server behind a Secure Gateway), on which ports, and what happens to traffic that doesn’t match any rule. Default behavior is deny all — an implicit Drop the traffic rule sits at the lowest priority and only matching allow-rules let traffic through.Documentation Index

The page
The Server Access policy page is a single ordered table of rules, grouped by priority bucket.| Column | What it shows |
|---|---|
| Priority | Rule precedence. Rules group by bucket: High, Medium, Low. Within a bucket, the rule added first wins. |
| Name | Friendly name for the rule. |
| Source | Who the rule applies to — a Usergroup, an individual user, or Any. |
| Destination → Objects | Which servers — a specific Secure Server, a group, or Any Server. |
| Destination → Services | Which ports/services — SSH, RDP, or a custom Service object defined under Objects. |
| Action | Accept the traffic or Drop the traffic. |
| Actions | Edit and delete affordances per rule row. |
First added policy has more precedence in the same priority bucket. Order within a priority bucket matters.
Adding a rule
Navigate to Server Access
Go to Policies → Server Access and click Add Secure Server Access Policy +.
Fill in the rule details
- Name — descriptive (e.g. DevOps SSH to prod).
- Priority — dropdown. Default High. Other values: Medium, Low.
- Source — dropdown of Usergroups and users from Managing Users & Groups. Tick Any to apply to all sources.
- Destination — dropdown of registered Secure Servers from Managing Secure Servers. Tick Any Server to apply to all.
- Service — dropdown of services/ports defined as Objects. Tick Any to apply to all services.
- Action — radio buttons: Accept the traffic (permit) or Drop the traffic (block).
Editing a rule
Click the edit icon on the rule’s row, change the relevant fields, and save.Deleting a rule
Click the delete icon on the rule’s row and confirm. The implicit deny-all row at the bottom cannot be deleted.Things to remember
- Default is deny. Until you add an Accept the traffic rule, no one can reach any Secure Server through Osto.
- Order within a priority bucket matters — the first matching rule wins. If two rules in the Medium bucket both match, the one you added first takes effect.
- Use specific over generic. Prefer user → specific server → specific service rules over broad Any rules. The audit trail in Logs → Secure Server is far more useful that way.
