Virtual Firewall: Change Verification, Undo and Change History
Every change you make to port forwarding and outgoing address rules is applied in a safe way, so that it cannot cut off your access by mistake. VPN user actions and the internal network access setting do not affect access to the firewall, so they are applied immediately.
How is a change applied?
- The change is applied to your firewall.
- The panel connects to the firewall again and checks that the change was applied correctly.
- If the check succeeds, the change becomes permanent.
- If it cannot be verified (for example, the change cut off access to the firewall), the firewall returns to its previous state by itself shortly afterwards. You then see a "the change is being rolled back" message.
This takes from a few seconds to half a minute. While a change is being verified, a second change cannot be made; you can try again a few seconds later.
Undoing the last change
The Undo last change button on the Port forwarding tab undoes your last add or remove within the last 24 hours: if the last change was adding a rule, that rule is removed; if it was removing a rule, the same rule is added again. Editing a rule is not undone with this button; you can edit the rule again if needed.
Change history
The Recent changes tab lists the latest changes made from the panel to your firewall, with their dates: adding, editing, removing and undoing rules, changes to internal network access and VPN user actions. Changes made by our team on your behalf are marked "(support team)".
Every action is recorded with the user who made it, the date and the IP address. If more than one user is defined on your account, a user needs the "manage services" permission to change the rules; users without it can only view them.
