SonicWall offers a way to encrypt incoming and outgoing data for organizations that rely on remote access.ĭoes SonicWall VPN offer a reliable service for businesses who need secure remote access? Let’s find out.Īs usual, VPNs stand or fall based on their security features. I'd be interested to know if anyone's tried it successfully actually, and if so what kind of config you're running.SonicWall VPN offers what it calls “a safe policy-enforced secure access to mission-critical applications and data.” That’s quite a lot to digest in one sentence, but it boils down to a simple offer. We do, however, have a second NSA2400 unit with a different (generally "simpler") config and running different services, on which we have installed this firmware without an issue, so YMMV with regard to 5.9.1.6. So at the moment we're living with the Netextender issues until we can spare the time to properly look into what's wrong with that firmware (or until the next release comes out which will hopefully be worth a try!). Suspicions at the time were maybe the WAN LB, DPI-SSL, or SSO features.
We had to roll back fairly quickly as we were in production hours before it became apparent, but the best we could glean from the logs was that it was detecting a massive quantity of false-positive RST / TCP floods for some reason, which basically meant no WAN access.
This caused another issue with our Sonicwall whereby it would become unresponsive after a period of uptime. We've tried applying this firmware update and it did actually resolve that particular issue, as well as a problem we were having with DPI-SSL.īut, and it's a big but. This is listed in the release notes for SonicOS 5.9.1.6, below.
After a few reconnections the tend to settle down but can disconnect when transferring a few MB of data at once. 02 and say we have the same problems running the latest NetExtender client and a Sonicwall NSA2400 - sessions are dropped randomly.
