You cannot reach file shares, printers or internal applications from home.
1. Open the VPN client (Cisco Secure Client / GlobalProtect / FortiClient depending on your firm). 2. Select the profile for your office and click Connect. 3. Sign in with your work email and password and approve the MFA prompt. 4. Wait for the Connected status, then retry the share or application. If it says the gateway is unreachable, test another website first (your internet may be down) and then submit a request with the exact error text.
