Final note

The scenario is also due to the fact that dialling in of several PPPoE connections to one DTAG xDSL connection has been forbidden since January 2015. A routing connection of the be.IP™ could also be configured via the previous PPPoE dial-in of the Internet gateway, however mechanisms that are automatically performed by the be.IP™ for VoIP must be taken over by the Internet gateway. These serve as examples:

- Quality of Service (prioritisation) for telephony packages

- Releases in the firewall for telephony

- NAT mechanisms for the unconnected ports of RTP data

- SRV requests via DNS (for tel.t-online.de) must be properly resolved.

The extremely comprehensive settings in NAT and SIF for forwarding all traffic from the Internet can, of course, be fine-tuned and limited to a greater extent.

This description is based on a completed Quick Start assistant, and if there are already port forwardings in the NAT, then the sequence should be observed, if necessary!
