WAF rule in 18.5.1 with Authentication Form with Passthrough is slow

juergenb52

Hi,

we had a WAF Rule with Authentication and a Form with Passthrough for a internal Webserver.
This rule was fine and performace for external users was ok.

Internal Webserver is Windows 2019,

After Migration to  18.5.1 the access to the interal server is realy slow.
Loading of pages takes very long.

We use the same WAF Rule with Authentication and a Form with Passthrough as before.

Can anyone help to find some hint´s why this seems so slow now?

Where can i start (logfiles, etc.)?

Thanks

Jürgen

    Hello Juergen ,

    There can be 2 reasons for this to happen,

    • It could be because of authentication token exchange between Sophos firewall and authentication server .
    • The WAF/Authentication service may be having high number of incoming connection , due to which this there is is delay in communication.

    In this case , we would need reverseproxy.log and access_server.log in debug . All you have to do is to provide both this logs by recreating the issue .

    DM me in case if you need anymore information for this .
