* Authentication Protocol: CHAP/MSCHAPv2 or PAP, but recommend CHAP, as L2TP is not encrypted
* Plain L2TP '''without any IPsec'''. This is important as some devices may not support disabling encryption on L2TP.
* Check that your ISP/mobile provider does not have features that will block 'VPN' services - eg Vodafone's 'SecureNet' will block access to our L2TP service but can usually be disabled via the provider's control pages/App/etc
 
=== Speed/Latency Tweaks ===
See: [[L2TP-Latency-Speed-Tweaks]]
 
===MTU===
You may have to set a lower MTU to accommodate the host ISP, possibly as low as 1462 (or lower for some ISPs). In theory fragments will work to allow 1500 MTU on our service, but fragments are inefficient, and if everyone sends fragmented packets that could degrade the service.
 
===Port forwarding on some 'Mobile Broadband' routers===
We have reports from a few customers who are using 4G/5G mobile data routers for 'mobile broadband' that whilst they do support L2TP they do not appear to port forward the static IP on the L2TP. The web UI suggests that portforwarding can be configured, but this seems to only portforward the IP address on the mobile data connection and not the IP address on the L2TP connection. We suggest that customers should report this as a bug to the supplier/manufacturer of the router. This can have an impact on using our L2TP service as these routers will be restircting the capabilities (ie portporwarding). A work-around is to to a separate ethernet router on your LAN to establish the tunnel.
