Users to Access External VPN

Christopher Paulin

All,

 

I'm using a SOPHOS XG as my firewall and I have a few users who are working as contractor to one of our customer.

As part of the requirement, the users need to connect to the customer's VPN to update their system.

Initially I created a group for the users and allow them to connect to the customer's VPN server (public IP) using the user/network rule.

They were able to connect but experiencing disconnection from time to time which is annoying them.

I set intrusion prevention, shaping and web policy to none; and appplication control to Allow All. I also made an Exception entry but they are still experiencing disconnection.

Any suggestion.

Thanks

    Check the vpn-logging at client-side and server side.

    If using SSL-VPN the Client-logging is very detailed.

    Hi Dirk,

     

    Thanks for the suggestion. This is the part of the client's log where they get disconnected.

    I checked my monitoring going to the customer's VPN server and there are no timeouts on that date/time.

    Any suggestion?

    Thanks

    Can you show the exception created?

  • 0 in reply to lferrara

    This is the Web Protect exception.

    The destination IP addresses are the public IP address of the customers VPN appliance (which is also Sophos XG).
