NetExtender client address range appears exhausted
We've used the SonicWall NSA 2600 and netextender for years without issues, firmware version is SonicOS Enhanced 188.8.131.52-52n, recently I've changed the router (it's not the first time) and with that, the public IP.
It worked for a couple of days, and then the issues started. The SRA logs return "NetExtender client address range appears exhausted" as a reason for not connecting anyone, then sometimes it starts working again for a single/ couple of users, then it stops again with absolutely no changes to the configuration, and a couple of ours ago it stopped working at all for everyone.
If I connect via Portal (the browser application) it works perfectly.
IP range for the VPN should be enough but to be safe I've increased it to 20 (for 4 connections) so it shouldn't be that.
I have no idea what I should do, nothing I did manage to solve the issue, and it's basically driving me crazy.
Thanks for the support.
That's an old firmware, you should probably read release notes and update. What you are describing may have been fixed in a later release.
Quick Question - you mentioned " SRA " in your post. can you please confirm if its actually the Firewall that is providing the IP addresses?
You should reach out to Sonicwall support and provide a summary of the Issue.
