With many people working remotely for one of my clients, we have a problem that the first two connections work fine but subsequent connections seem to get no response from the router and time out. Is there a 'simultaneous connections' limit that I don't know about?
Details:
- v2762 with firmware 3.9.6.2_BT.
- Remote users are on W10 with Microsoft built-in VPN.
- All remote users defined as L2TP with IPSec (PSK) and policy set to 'Must'. They show in Connection Management as "L2TP AES-SHA1 Auth".

Per the specs: https://www.draytek.co.uk/products/soho/vigor-2762-series-adsl-vdsl-router#specifications, "2 Concurrent active VPN Tunnels"

Upgrade to 2865 to get more: "Up to 32 active VPN tunnels - including up to 16 SSL VPN or OpenVPN Tunnel"
