DA / Expert Assist Not Connecting Over VPN

jmai

Hi, when a PC is on VPN (Cisco AnyConnect) it can't connect to other PCs or receive connections from other PCs. It just times out when connecting to port 2000 in the browser. However, I am showing port 2000 is open when doing nmap scan, also the firewall is showing the traffic is allowed and a packet capture shows traffic is passing to and from. When the PCs are both on the local network it connects. RDP connections are working fine btw. Anyone ever run into this issue?

    I can't diagnose the exact cause remotely, here are some steps to help troubleshoot:

    1. Verify Port Settings:

    Double-check that port 2000 is indeed used by the application you're trying to connect to. Different applications might use different ports.

    Ensure the VPN configuration allows inbound and outbound connections for the specific port or protocol used by the application.

    2. Check Split Tunneling:

    If your VPN uses split tunneling, make sure the application or computer trying to connect isn't routed through the VPN tunnel by default. Configure split tunneling accordingly.

    3. Analyze Packet Capture:

    Deeper analysis of the packet capture might reveal details like specific errors or limitations blocking the connection. Look for clues related to port 2000 specifically.

    4. Consider Alternative Ports:

    If possible, try connecting through a different port used koowspin by the application. This might be a workaround if port 2000 is restricted for some reason.
