Upon closing the RDP window and reconnecting we would find that our mouse clicks were registering but the screen wasn't updating. enabling fragmentation would help SonicWall handle fragmented IPsec packets.

Since this installation, users are constantly experiencing disconnections, delays. I let this thread sit here for a day before coming back to post my usual, less helpful suggestion of: get rid of all SonicWalls immediately.

Support for 100 VPN users? This could help you narrow it down to an ISP and or a specific site. Purpose is to access the file server. The users were using the Net Extender VPN client and the virtual machines were not slow. As soon as I shut down the client, my network speed goes back to normal. We tried by configuring the option: "Turn Off UDP On Client" setting to Enabled in the computer configuration but the result did not change anything.

Do you require 24x7 phone support? Any clues on on trying to troubleshoot this issue? Navigate to VPN | Advanced Settings. Then check the usage at both sites over a day or so. This sounds similar to an issue that we were experiencing. The old one has been decommissioned. That should tell you something right there. Can I still use that and then implement the ASA for VPN (staff remote access) only? We have exactly the same problem. I've ran into speed issues with the SSL VPN on the NSA4500 series. Any clues on on trying to troubleshoot this issue? The firewall CPU usage is fine and the egress/ingress is fine to. I forgot to mention that when we do have this issue, even if I use logmein, that is slow too. Have a good one. All much better products. Cisco, Juniper, Arista, Fortinet, and more are welcome. Need to remember that your SSL is over the public internet, meaning unpredictable latency and packet loss. Speed test are fine. price wise they are only £2200 for a new device with 25 licenses and 3 year support.

Turn off unnecessary services on the SonicWall. Did you get a response regarding this problem? Generally speaking if you just assume a device can meet some expectation without at least the vendor officially claiming they can do it, you're gonna have a bad time. Replace the SonicWALL. Enable Fragmented Packet Handling in VPN Advanced Settings. In the case of SMB traffic, what is a viable solution? SMB is notorious for slow transfers over high latency links (30ms can be considered high in this case).

The protocol wasn't designed for this and so doesn't lend itself well to speed over WAN links. I do not have internet traffic routed through my VPN. on the TZ600. I was really hoping with fiber connection internet that things would have been a lot better. Let us know how it goes. Assume I’d just need to purchase a anyconnect 10 pack of ssl VPN licenses?
