Solved: How do I fix extra route connection issue in Windows routing table when connecting to SSLVPN

This article describes how to fix the issue where after connecting to SSLVPN via FortiClient, users may experience connection issues for up to 10 minutes on Dell laptops with Windows 10/11.

This affects both setups with split-tunneling enabled, where FortiClient pushes the split subnets to the Windows routing table and setup where all user traffic is sent to the tunnel.


  • FortiClient 6.4, 7.0, FortiGate 6.4, 7.0
  • Windows 10, Windows 11
  • Dell laptops with Dell Optimizer software

Problem Symptom

When checking the routing table with route print in cmd, an extra route can be seen that points to the local gateway.

This can disrupt the connection to the internal DNS server and/or domain controller.

Example routing table right after connecting

Network Destination | Netmask | Gateway | Interface | Metric 45 1 46 <--- Route injected via VPN but pointing to which is user local gateway

After routing update

Network Destination | Netmask | Gateway | Interface Metric 50 1 2 <--- Route updated to SSLVPN gateway
