I setup an SSL VPN on a Sonicwall SOHO 250, running SonicOS 6.5.4.0. It connects just fine, but disconnects after 3-4 minutes.
- Users setup with TOTP
- VPN Timeout Changed to 60 Minutes
- Created Firewall rule to extend TCP timeout to 120 minutes for terminal services
- Changed user timeout to 60 minutes
- Happens with both Netextender and Sonicwall Mobile Connect apps
- No other custom firewall rules aside from those stated in this post
Does anyone have any ideas to fix this issue?
