Hi, it was mentioned in this topic > [@Packet Broker TTN to TTI ttn-v2-eu](https://www.thethingsnetwork.org/forum/t/packet-broker-ttn-to-tti-ttn-v2-eu/38036): > > I have both a TTN & TTI gateway when did TTN start forwarding to TTI ? In TTI v3 console uplink appears as follows (NB. fragment of msg) “rx\_metadata”: [ { “gateway\_ids”: { “gateway\_id”: “packetbroker” }, “packet\_broker”: { “message\_id”: “01EBHKCBXABZ6606WBC53CSR4B”, “forwarder\_net\_id”: “000013”, “forwarder\_id”: “ttn-v2-eu”, “home\_network\_net\_id”: “000013”, that there is some forwarding of traffic from TTN to TTI. Is this still the case? Does anything special need to be configured either in TTN, gateway (using TTIG) or in TTI for this to work? ---

I expect there will be more information on this subject available next week at the TTN conference. So you might have to wait a few days… ---

Yes I have two gateways one TTI & one TTN uplinks from TTN are routed via **Pack Broker** to TTI you don’t have to do anything it’s just happens 🙂 ---

Would that work for network joins as well? ---

> [@phaber](#): > > Would that work for network joins as well? Gateways on V2 (the community network) will work fine with V3 applications (TTI & TTN new) including joins, downlinks etc . The reverse does **not** work. ---
