We have something of an informal L2TP service. It works as backup to broadband lines, but also as a stand alone service with IPv4 and IPv6 via L2TP with usage charging. We plan to make changes to billing for this, moving away from a complex units system to a simple one. The planned new package is £10/month for 100Mb/s and 1 Terabyte download allowance (after which capped to 3Mb/s). We plan to contact existing users in due course and announce a proper start date for this as our only stand-alone L2TP service offering. Existing DSL users can use L2TP as a back-up as part of their package. Any queries, please contact us.
