Nat from Lan to OPT1?



  • Hi,

    I'm feeling like this should be possible but I'm going around in circles with it and having no success.

    I have: LAN 192.168.1.1/24 and OPT1 192.168.2.1/24.

    I was using OPT1 to separate out my WEP wifi, so I can feel a little more secure that it can't get onto the LAN without me opening the firewall.
    I'm also using the captive portal on OPT1 so I'd prefer not to loose that by solving this with by bridging.

    The problem is that my Tivo on OPT1 can't been seen by my computer on the LAN because the Tivo software only "finds" Tivos which are in the same subnet as the machine it is running on.

    Is there anyway I can NAT things (or any other solution) to make an IP (or specific ports on that IP) on the OPT1 appear, from my LAN, to be part of the LAN subnet?

    Thanks in advance!



  • No. I guess this application depends on broadcasts that don't leave the own subnet. NAT won't help here. Maybe setting PPTP up so the client at OPT1 can get an IP from LAN and thus be a LAN member would help (ugly but might work).



  • Thanks for the fast response. I believe it's involving Rendezvous/Bonjour, which looks like it can work with multiple subnets, but not without some DNS wizardry…

    I'm not sure Tivo would be able to use PTPP, so I'm guessing I'll have to either bridge or rethink things. :/
