    We have enabled SSL on our firewall which now truncates packets and stops the Ajax from working.
    When investigating this issue,  our team and sonicwall support determined that indeed we are losing packets.
    The suggestion from sonicwall was that we needed to low the packet size as the firewall is seeing to large of packets and dropping some of them.

    The firewall limit in SSL is 1500 MTU's  

    It appears that the Telerik control is much larger than that and we need help on fixing this problem
    How can we get the telerik controls to work within the packet maximum of 1500 MTU?

    Hi randall,

    ASP.NET and Telerik have nothing to do with the MTU size. Further, the MTU is set on the client machine level through a registry modification, not through the application itself.

    Kind regards,
