My SSL VPN is setup to use TCP, but I read the UDP will be quicker. Is this the case?

Do I simply set UDP instead on TCP in the Settings?  I tried this and it didn't work?

Is SSL VPN the not secure, and quickest method?  We have end users report the connection to the VPN is really slow - much slower than their local ISP connection.



  • Hi Andrew and welcome to the UTM Community!

    UDP is faster.  When you change to UDP each user must get an updated configuration file.  Alternatively, they can edit their configuration file to replace tcp with udp in line 4:

    C:\Program Files (x86)\Sophos\Sophos SSL VPN Client\config\user@FQDN\user@FQDN.ovpn

    Also, you might want to confirm that the MTU is not 576 on your External interface.
