APM VPN LDAP POOL can't contact ldap server.
Hi, I have a question regarding APM VPN and LDAP authentication. When I configure the LDAP server using the direct LDAP Server IP, the authentication works fine. However, when I use a Pool with the same LDAP Server IP, it shows the error message: "Can't contact LDAP server." From the packet capture, it seems that no traffic is being sent out at all. Is there any specific configuration I need to adjust for LDAP Pool settings? Thank you.
APM webtop – problem with websockets for Serverside Blazor app
Dear community, We have a web application built with Blazor server side rendering that utilizes SignalR (websockets) and runs on a Windows server with IIS (i.e. not web assembly). Virtual sever: the site runs as intended! Webtop + virtual sever: The site will render and SSO works, but any page using SignalR will loose interactivity as the websocket handshake times out. We have tried to disable websockets on the server which makes SignalR use long polling as a fallback. The web browser displays a different error message but behaves the same otherwise (have not dug deeper as we intend to use websockets in production). I would greatly appreciate any guidance on what to do! This is the log from the blazor web app (behind webtop + virtual server): 2025-09-18 16:50:26 Debug Microsoft.AspNetCore.SignalR.Internal.DefaultHubProtocolResolver Registered SignalR Protocol: json, implemented by Microsoft.AspNetCore.SignalR.Protocol.JsonHubProtocol. 2025-09-18 16:50:26 Debug Microsoft.AspNetCore.SignalR.Internal.DefaultHubProtocolResolver Registered SignalR Protocol: blazorpack, implemented by Microsoft.AspNetCore.Components.Server.BlazorPack.BlazorPackHubProtocol. 2025-09-18 16:50:27 Debug Microsoft.AspNetCore.Http.Connections.Internal.HttpConnectionManager New connection XQNqGM4oGkm0P1v4NECJ9g created. 2025-09-18 16:50:27 Debug Microsoft.AspNetCore.Http.Connections.Internal.HttpConnectionDispatcher Sending negotiation response. 2025-09-18 16:50:27 Debug Microsoft.AspNetCore.Http.Connections.Internal.HttpConnectionDispatcher Establishing new connection. 2025-09-18 16:50:27 Debug Microsoft.AspNetCore.SignalR.HubConnectionHandler OnConnectedAsync started. 2025-09-18 16:50:27 Debug Microsoft.AspNetCore.Http.Connections.Internal.Transports.WebSocketsTransport Socket opened using Sub-Protocol: '(null)'. 2025-09-18 16:50:42 Debug Microsoft.AspNetCore.SignalR.HubConnectionContext Handshake was canceled. 2025-09-18 16:50:42 Debug Microsoft.AspNetCore.Http.Connections.Internal.Transports.WebSocketsTransport Waiting for the client to close the socket. 2025-09-18 16:50:42 Debug Microsoft.AspNetCore.Http.Connections.Internal.Transports.WebSocketsTransport Socket closed. 2025-09-18 16:50:42 Debug Microsoft.AspNetCore.Http.Connections.Internal.HttpConnectionManager Removing connection xVt0cL2a0gpMOiJROyJxhw from the list of connections.

Checkpoint Web Smartconsole behind reverse proxy.
Does anyone have any experience at trying (and hopefully suceeding) to put a Checkpoint (CP) FW Provider-1 based web smartconsole behind a reverse proxy. The thing is that CP use local IP addresses to identify one of a selection of management module instances. And they use webtransport/websockets to connect from these mgmt modules back to a browser for displaying FW policies and log data etc. That all seems fairly OK but they don't anchor it using the connection ID and so the raw IPs (of what they call the domain blade/instance) get passed to the browser. But we would prefer to NAT/hide/reIP the server (domain) side IPs and not have the internal server/domain IPs sent along to the browser. Part of the conversation, and some wrapper text from me, from the server to the client follows: *** We wish to use access to various customer domains using the /smartconsole web interface. But the access has to be behind a reverse proxy (F5 vIP) and after the initial logon using the CMA IP behind a vIP (so address the browser sees is a service public one) you get a screen where the domain is listed and after selecting continue you get redirected seperately to the CMA IP in an internal JSON/javascript message. Hence breaking the attempt to have the CMA behind a reverse proxy. *** {"data":{"loginToDomain":{"transportOtt":"107ad894-253d-4638-aa31-1c3e7d23172a","transportUrl":"https://100.64.20.29:443/smartconsole/transport","__typename":"LoginToDomainResponse"}}} ***How APM GET IOS UUID & Andriod MAC
Hello Expert, Recently, there has been a requirement to restrict the MAC addresses or UUIDs of source mobile devices. Android devices will utilise the method of obtaining the MAC address. https://my.f5.com/manage/s/article/K13731#ai-recommendations-54 expr {[mcget {session.client.mac_address}] == "50:6B:8D:xx:xx:xx" iOS devices will utilise the method of obtaining the UUID. https://my.f5.com/manage/s/article/K12749 expr {[mcget {session.client.unique_id}] == "8ccaf965e51e3077" As illustrated below: Would this approach successfully fulfil my requirements? Thanks.
