We installed SD-Wan a few months ago in a very simple single vlan spoke and hub setup--just the 2 locations, spoke and hub involved. Both locations has 1000/1000Mbps connections (verified both are getting expected speeds). When we try to copy a file from a Windows 2022 server on the hub to a windows 10 client (all fully patched) on the spoke, the file copy speeds (as well as iperf) peak at about 3Mbps. This makes it very hard for the users to get work done as the files their software uses are usually fairly large so everything takes a long time to open/save and files are getting corrupted regularly.   All AMP/IDP services are disabled on the spoke; tunnel all is on as we need all traffic to exit the HUB. We did all of the standard and even standard troubleshooting (disablebandwidththrottling registry edit, SMB tuning on the server, checking MTU, etc.) all to no avail.    I went to the spoke location and scheduled a call with support (we get the service through ATT) who got a Meraki tech on the line. We spent 2 hours looking at things and testing with iPerf, testing file copy speeds between 2 machines on the spoke (worked fine) and at the end of it all, the final "answer" from the Meraki tech was that this is expected behavior with SD-Wan and SMB. If this is the case, how do people solve SD-Wan locations using fileshares? It seems like this should be a pretty standard and common setup, but is there really no solution to using SMB over SD-Wan (I confirmed we are using SMB3.1.1; packet captures show SMB2, SMB1 is definitely disabled).    I was looking at maybe getting a better connection at the spoke (it is VZN Fios, so Fiber but shared) like DIA, but it's much more expensive and if SD-Wan is incompatible with SMB it wouldn't fix the issue anyway.  ...

I'm getting terrible results in Windows file sharing on my Hub and Single Spoke setup. Speed test shows ~230Mbps down/200Mbps up, but when I go to copy a file from a Windows 22 server on the Hub to a Win 10 machine on the spoke, the file copy speed hangs at about 1-3MB/s, maxing out at 4. The ethernet interface show 1GB speed so I'm not sure why the performance is so bad.  Also using Umbrella if that matters.  Latency and Loss all seem reasonable so don't think it's that: Thanks for any ideas.  ...

We have a single Spoke and Hub SD-Wan set up with only the one spoke and the hub. The hub users connect to Windows machines on the hub LAN to work (open files to work on them in various programs, group policy, printers are all on these servers) and there seems to be connectivity issues sometimes. Some programs crash. Some print jobs crash or take a long time or duplicate. Some of the errors I've seen point to connectivity issues with the server on the hub. The only events I see in the Spoke's event logs are DHCP events and SNORT update, nothing about connection errors.  Any ideas where I could look or what might be causing these issues? Thanks. ...

We are licensed for Umbrella SIG Advantage and are in the process of setting things up. I have fired up the 2 local appliances and have DHCP setting those as DNS for everyone. However, instead of getting block pages, there are still a lot of blocks that result in the page just timing out. This made me wonder: if using Umbrella, should I get rid of all of the Category blocks and threat protection settings on the MX devices? We have yet to set up the Network tunnel so for now are just testing DNS, but was curious what other people have done.   ... View more
