Internet speed decreased when connected to ssl VPN

We are configured SSL VPN in tunnel all mode so that remote users can access internet through our firewall. But we observed that when users are connected to ssl vpn they are getting less internet speed over the VPN. We are having 100mbps internet link and we are routing internet traffic of SSL vpn users through this link But still when we do speed test on user machine in shows users are getting nternet speed 1-2 mbps.

Any suggestion??

  • Hello @Ninad94,

    You have 100 Mbps internet link on the firewall side or client side? The overall speed after the connection is dependent on both ends. Also, due to TCP based SSL connection, the overhead is a little high and usually the speeds are not that great over SSLVPN.

    If possible could you test GVC client too from the same location and see if that works out better for you?

    Hi @shiprasahu93

    We have 100 mbps link at firewall side. SSL vpn users are routed thorugh firewall for internet access. When they are connected to ssl vpn getting 2-3 mbps internet speed.

  • @Ninad94,

    What about the speed on the client side who is connecting? If they also do not have similar speeds, we cannot achieve higher bandwidth as they are using their ISP to build the SSLVPN connection.
