WARFRAME CONNECTION CHECKLIST Record your own values; the guide's LAN addresses are examples. Platform / game version: Date and time: Router model / firmware: Connection: home / hotspot / campus / VPN VPN provider, location and NAT mode (if used): Exact Warframe network-analysis message: Game UDP pair: Gaming device LAN IPv4: DHCP reservation: Router WAN IPv4 (compare privately with home public IPv4 outside VPN): ISP confirms public IPv4 with incoming UDP access: yes / no / unknown Second router upstream: yes / no / unknown ONE CHANGE AT A TIME [ ] Allow Warframe through the active firewall profile. [ ] Check router UPnP; on PC, check the game UPnP/NAT-PMP setting too. [ ] If automatic mapping works, keep it and test invites. [ ] Give a second PC a different in-game pair before creating its rules. [ ] If using manual rules, match protocol UDP + both game ports + LAN IP. [ ] Follow the game's manual setup guidance for disabling automatic mapping. [ ] Check other devices before changing router-wide UPnP. [ ] Check CGNAT / double NAT if the warning remains. Device 1: LAN IP ______ ; UDP pair ______ / ______ Device 2: LAN IP ______ ; UDP pair ______ / ______ VERIFICATION Network-analysis message after change: I can join a friend: yes / no Friend can join me: yes / no Mission loads with both players: yes / no Voice chat works (if used): yes / no Second peer tested: Both home devices tested at once: Result after restarting / reconnecting VPN: NEXT ACTION [ ] Warning cleared and invites work: save settings and stop. [ ] Strict NAT remains: check the home upstream connection or VPN route. [ ] Warning cleared but invites fail: compare with another friend. [ ] Relevant route already checked: send results to the provider or Warframe Support. FOR SUPPORT Attach the exact warning, platform, router model, selected UDP ports and results. On PC, use the launcher's gear menu > Get Logs when requested. Send logs privately to Warframe Support; do not post them publicly.
