Our DVR appliances provides some tools for offsite review and management, but recently we wished to access internal network cameras from offsite, with a VPN through our SonicWALL TZ190 firewall.
It turns out that simply downloading and installing any of the posted SonicWALL Global VPN Clients (GVC) has been preventing our HP laptop machines from accessing ANY network, via either the RealTek LAN card or the Atheros WIFI card.
We've Googled references to similar experiences with those attempting to run SonicWALL GVC on some tablet PCs. We'd be delighted to use SonicWALL support, but they won't allow us to purchase a maintenance contract because the TZ 190 appliance is past end of life, and they won't provide support without a maintenance contract.
Never mind that the issue for us is non-appliance-specific -- simply installing their GVC kills all network access for that PC until GVC is uninstalled. Once it's uninstalled, everything works fine, just like before the installation.
Has anyone had any experience with remote VPN to a LAN with GVC, and any suggestions with this problem?
P.S. I understand and am very comfortable with an out-of-scope-for-our-site removal. Mostly this is a Hail Mary pass.
