Moving from NSA3600 to something new for an office of 100 people. Those who did not stay with SonicWALL, who did you choose? For those who havent yet but will where you go? Simplicity and Wi-Fi integration would be the preference. Thanks

Hello all!

We just recently upgraded all of our clients /CSE Apps to the most current (4.2.0) and are getting constant application crashes. Our firewalls are patched to the newest firmware. Devices are on Windows 11 25H2. Event log gives us -

- The Sonicwall CSE Admin Service service terminated unexpectedly. Event 7034
- The Sonicwall CSE Wireguard Service service terminated unexpectedly. Event 7034
- The Sonicwall CSE Updater Service service terminated unexpectedly. Event 7034

We have rolled back which seems to fix the issue but obviously not ideal. I do have a ticket open with Sonicwall currently, but my experience with another unresolved issue recently with CSE support has not left me confident they will resolve.

Anyone experiencing anything similar?

Hey all. Just taken on an IT manager role and inherited infrastructure that needs some work. gonna propose a hardware refresh and want some outside input before the quotes come through.

The setup:

10 sites, head office plus 9 remote construction cabins

All sites running SonicWall firewalls, Netgear switches, Unifi APs

Head office is different, it's been refreshed already and is all Unifi (switches, APs, CloudKey)

Only 2 of the SonicWalls are still in support, so the rest need replacing

Our VAR is quoting us on three options: SonicWall, Fortinet, and Unifi.

• SonicWall - already in place everywhere, and 2 units don't need replacing at all since they're still current. Least disruption by far. Also our end users are already using SonicWall's client VPN for accessing our fileserver.
• Fortinet - I came from a Fortigate environment so I actually know my way around it a bit. Not sure how much weight to give that when making the call though.
• Unifi - apparently the cheapest option and would tie everything in with the head office setup. Main concern I keep hearing is that it's not really up to scratch as a proper security appliance according to industry friends who know networking and security better than I do, specifically around tweaking IPS and web filtering. Not sure if that's a fair criticism , as im taking their word for it

networking isn't my strongest area. Is Unifi actually viable for a setup like this or is it more of a home/prosumer thing? And is the familiarity argument for Fortinet actually worth anything in practice? the VAR seems to think Unifi will be my best bet and doesn't place too much importance on the lack of tweaking ability for security policies etc. as that's more an endpoint configuration thing nowadays and it's irrelevant when people work from home. but that statement "feels" like a copout, I just cant articulate why

opinions greatly appreciated as this'll be a costly change and I am motivated to get it right. Thanks so much in advance

Gen 8's are unable to import configs from previous model unless VLAN interfaces are deleted on the previous model first before exporting. Import config then re-create the VLANs and any associated DHCP scopes manually on the Gen 8.

Why is this?

I've done a good few so far but some have a WAN interface that is a VLAN from the ISP so I can't delete it to export.

Hi everybody,

we got a Gen8 firewall from SonicWall in productive (NSa3800) - every 3-4 weeks it starts that the primary device gets an issue with fan #1 failing again and again. After replacing the device, it works for some time and then shows the same behavior again.

I suspect this comes from the new architecture based on more powerful CPUs (with more heat to be pumped out) as the Gen7 and older firewalls never had this issue.. It's in the same rack as the Gen7 devices and also primary and secondary are directly next to each other.. No difference there..

Somebody else out there who faces these problems? Is the cooling system in the device prone to issues maybe?

We got a ticket open on this, I'm just interested whether somebody else faces these issues as well.

I have a setup where wired devices are getting DHCP from the domain controller, and wifi devices are getting DHCP (in two different VLANS) from the Sonicwall. Not sure if this is best practice, but it all works fine.

I'm getting repeated alert 1068s from the Sonicwall for "Multiple DHCP Servers are detected on network". Well, yes - there are 2, so that seems right. I cannot find a way to configure the Sonicwall to expect 2 as the normal condition and then alert if it ever detects >2. I think that only leaves the choice to turn off this alert, lest I continue to get spammed with these alerts. The IP address in the alert is the domain controller, so I can only presume (since this alert is not elaborated-upon in any documentation I have found) that the alert is triggered if it finds DHCP traffic going anywhere by the DHCP configuration on the Sonicwall itself. This would lead to the conclusion that this alert doesn't work at all if the Sonicwall isn't doing DHCP at all, but who knows.

I have enabled DHCP Guarding on the switches (Unifi) and specified the 2 known DHCP servers, but that hasn't changed the problem, which seems to support this conclusion.

Am I doing anything wrong here? Is there a configuration I'm missing that would let that alert work as desired?

Trying to get SAML authentication (office 365) to work on SSL VPN.

Managed to work through various bugs to the point where is successfully takes the username + password + MFA pin but then the connection just dies with no error.

Logs in the client show it's a permissions error, but can't figure out what's causing it?

Is SonicOS 7.0.1-5169 getting an update to patch April 2026 Vulnerabilities?

If not, is there any harm in upgrading from 7.0.1-5169 directly to 7.3.2-7010 or will it break things?

any way to do this? we dont require licenses on these boxes for the remote offices. kinda an annoyance....

Anyone having issues where their Sonicwalls are going offline behind Verizon FIOS?

I'm able to ping the Verizon ISP gateway and firewall IP, but the device is dropping the connection. I've disabled probing the SonicWall responder

Does anyone use a Gen 8 TZ firewall with redundant power adapters? Are there any issues?

I assume you just buy a 2nd power adapter and plug it in to another UPS/circuit so both are running at the same time from different power sources. Are you able to check AC adapter status in the UI?

Thanks

We are noticing high ping times and slowliness when browsing to services (internal websites) over the ssl vpn service. Is this common or did something change with the latest gen8 making this slower?

Running latest firmware on a NSA2800 with a fiber connection 8.5/1.5 gbps... the network is not the problem.

A user confirmed that if they use the ipsec vpn service, it works much faster. Or does sslvpn just have such a high overhead?

We use split tunneling.

Quick question, do you leave CSE set to automatically start? It is set that way by default and it starts when the users are in the office. Just wondering if that causes any issues?

good afternoon, i have multiple tablets that work just fine but one of the tablets say no services found. I plug once tablet in to where it needs to be and it works just fine but when i plug this laptop in to the same spot it still says no services found. it appears all the settings are the same. i have unistalled and reinstalled multiple times. I’ve ended it as a task in task manager. im not sure what else to do.

I do I.T. for a city but I’m new and have never worked with sonic wall cloud secure edge. Is there anybody would could give advice to fix this problem or how to contact someone? Their page is kind of a pain in order to find a number or somebody to talk with…or I’m not looking in the right places.

Please and thank you

This used to work fine - no issues whatsoever. We have not changed anything in our environment except a SonicWall firmware applied at the beginning of April.

We have 4x Windows 11 PCs at the main site and a Synology NAS at the remote site. We were using Windows backup to backup sys images of each PC to a shared folder on the NAS. We have 1Gb/1Gb lines at both sites.

Since the beginning of April, as soon as the backup starts running, our Papercut Ricoh printers at the main site lose connection with the Papercut server VM (port 9192) that is sitting in Azure - there is another vpn tunnel setup on the same sonicwall.

As soon as the backup is stopped, they reconnect.

So we tried using VEEAM backup instead, and using the traffic throttling setting reduced down as far as 50mbps - still the same issue.

What has changed in the SonicWall firmware?

Is the DPI/IDS/IPS struggling to work with the backup traffic?
