Ok so I'm trying to setup port forwarding for Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB vpn3.6 on an N16.
On Proto Ext Ports Int Address Description On Both 32400 192.168.1.2 Plex On Both 3389 192.168.1.2 RDP On Both 55669 192.168.1.2 Torrents On Both 5800,5900 192.168.1.3 VNC
The 192.168.1.2 is a static DHCP'd address. I have tried doing all sorts of stuff from different external addresses forwarding to correct internal ports, using completely different internal addressing schemes (192.168.1.100), to using the direct WAN IP instead of the DDNS address. Nothing gets forwarded. I did a 30/30/30 but that didn't wrork. Everything else works (including QoS and wireless), it does work over the LAN, and worked on my old wrt56gv3 (stock).
If you need any further info let me know.
