This article discusses potential issue and their resolution related to retrieving network licenses over VPN.

Slow performance of obtaining network licenses over VPN

CSi products can utilize network licenses using Cisco AnyConnect VPN. Download the Configuration Guide for setting up "Safenet Cisco AnnyConnect Client" on your server.

When there is a slow performance of obtaining network licenses over VPN or when the network licenses cannot be obtained at all, it may help to adjust the firewall and VPN settings to "Enable fragmented traffic. Try limiting the packet size on your license server as follows:

1) Determine the network name you are using on server. 

     Start a command prompt ad administrator and type the following parameters to determine the network connection name in use.

       netsh interface ipv4 show subinterfaces

2) Set the mtu size to say 1359

      netsh interface ipv4 set subinterface "Local Area Connection" mtu=1359 store=persistent

      in the above example “Local Area Connection” is the name of internet connection used on server.

For troubleshooting purposes, you may also want to check out the license via WCommute.exe to confirm that the issue is indeed related to retrieving the license over the network.
