In above setup:
* LAN side TiVo IP is 192.168.10.184
* WAN port 5080 maps to TiVo port 80
* WAN port 5443 maps to TiVo port 443
* WAN port 51413 maps to TiVo port 1413
So then in kmttg config for out of home use, in the Tivos tab for the particular TiVo you would set:
* Tivo Name = whatever
* Tivo IP # = <your router WAN IP OR DDNS NAME>
* wan http port = 5080
* wan https port = 5443
* wan rpc port = 51413
