  • Sorry to hera That @NickEbstarLtd But I think there is no hope that this ever gets resolved since the also closed our ticket, since we where not able to provide Logs of that blocked devices and after a reboot everything is gone. Lucky for us, it did not happen again after these 4 devices.. Regards Simon
  • Hi Jack, devices with the 7.1.1-740 have that known bug that you mentioned. We had that also. But in that case, the Management Plane is on 100%.. In my case, it is a 7.0.1-5145 Firmware and the Data Plane is on 100%. So it is a different issue. Until now, a reboot fixed the issue and it didn't come back on the same device.
  • Only the firmware 7.0.1-5145 of the TZx70 is affected. After the reboot of the device it didn't occur again on the same device.. So it's not a magior issue, but it is anoying. For now there there affected TZ270,TZ370,TZ470. The upgrade to 7.1.1. was not suggested as first step of resolution, since that provides new…
  • Hey @MartinMP , for what firmware do you wait? 7.1.1. is already released, but since that has some completely new features, even the support did not suggest an update as first solution. We have now also TZ270 afected.. But very random. Until now 4. Do you have SNMP enabled on them? (that's what support asked me) Regards…
  • The problem is, that the device is very unresponsive when this happens. Enabling SSH, connection etc. can be challenging there. All firewalls are on remote locations. In the last cases, businesses where completely blocked and my colleague needed a fix asap. But maybe next time when it happens on an other FW, we have a bit…
  • If someone has the same kind of issue.. We where now able to solve the issue with Sonicwall Support. The problem occured, when on the WAN Interface of the Sonicwall the DNS Server of Cloudflare 1.1.1.1 was used. After changing to a different DNS , in our example 9.9.9.10 the issue was solved and we had no additional delay…
  • Sonicwall Support change now the CFS Server to webcfs07 (IMHO UK) for all EMEA Sonicwalls. But for my problem, this was not the solution.
  • I noticed the issue on multiple Sonicwalls. Even Gen6.. IMHO they damaged something months ago with CFS signature Updates. Otherwise I have no explanation. @BWC Can you start a capture for HTTP/HTTPS with dest-IP 93.184.216.34 and then open the Webpage www.example.com ? It is important that you did not open this website in…
  • In the meantime Sonicwall Support responded, that this is a normal behaviour. They mean the drops. But a latency of 3 seconds and mor e per pageload of a new site, is not normal. @ALL Can technicians of Europe post what CFS get's configured in their Gen7 Sonciwalls? On that one that I've checked it was always the webcfs06…
  • Is there a new issue? By opening the Base URL i get: with the complete link it opens: but when I hit submit i get the same message as you got 1 month ago..
  • On sonicwalls you can add Vlans to an Interface by adding virtual sub-interfaces. https://www.sonicwall.com/support/knowledge-base/how-can-i-configure-sub-interfaces/170503889544086/
  • What SIEM solution do you use?
  • Does someone of the Sonicwall Employees here have some information?
  • You can simply enable One-Time-Password on selected Users and test how it works: IMHO Group Level is not possible. At least on SMA 500v. the only other option is to enable it on domain Level.
  • Hi Manish, By W1 and W0 you mean X1 and X0? If you want to manage the Sonicwall from the Vlan10 you have to enable the HTTPS-Management on the X0:V10 Interface. Is internet working for the devices on LAN and VLAN? Can you post some screenshots of your Firewall Rules and Configuration to better understand your situation?
