![]() ![]() Reboot SonicWall after changing services.Ģ. In the Sonicwall admin panel: disable BWM This is important for VPN performance.ġc. In the SonicWall admin panel: "security services > basic setup > change it to "performance optimized". There is a bit more info on configuring the Sonicwall through the web interface here, may want to check the current settings and compare to these notes:ġb. Lowering it to 1404 may yield a bit better performance, try it. You may also check the MTU on the Sonicwall WAN interface. It is a good idea to have clients configured to use lower MTU, like ~1400 bytes.ġa. Often the MTU is an issue with VPNs because of additional tunneling/encapsulation. I am not very familiar with the SonicWall appliances, but I would first try different configuration settings.ġ. Would there be a VPN appliance we could set alongside the SonicWall that would have better throughput? I could probably get the powers that be to drop maybe $1000 to $1500 on a fix but that's about it. So I guess my question is, without having the engineers all bring their systems back to work and then remote in, what would be a practical alternative? Since the working remotely thing may come to an end in a month or two (or go on for another year, for all I can guess), I am hesitant to recommend spending a bunch of money on a solution. From what I have read, SonicWall's implementation of VPN is the culprit in our case. I know VPNs are always going to be slower than the line speed but this is ridiculous. Clients on the local network have no issues. During normal business hours people struggle. If nobody else is connected via VPN, a single user can be kinda productive. Access loses it's mind more than is pleasant. Network shared Excel files frequently need to be opened in protected mode. Problem: horrifically slow throughput across the SonicWall (wasn't my decision) SSL VPN. Were it me I would have had them leave their systems at work and remote in with TeamViewer or maybe AnyDesk. When things went sideways the decision was made (which I objected to) to send the whole Engineering Department home with their workstations and dual monitor setups, to which I replied "OK, but for that to work you'll need to set up a VPN or something so they can access network resources". Long story short, the whole pandemic thing tossed some chaos into our day-to-day and who knows how long this whole working remotely thing is going to go on. ![]()
