Just so I understand this right,...
Because I've been messing around with MythTV settings, playback configuration user setting, etc., before getting to the network configuration...
Q: Which nic should the Internet connection be on, and which should the internal network be on,... ? (onboard versus card)
Makes no difference to the system. Typically the onboard will be detected first, unless it is one of the blacklisted prior to driver support when kubu loads... then it will be backwards. LMCE doesn't care one way or the other. It figures out which one has internet coming in and makes that external, and spits dhcp on the other. However if one is gigabit, and one is not, I would recommend specifying the gigabit for your internal network.
Q: And can LinuxMCE be connected to a router which Does DHCP for any direct connectly devices?
(Specifically, I have a Micsaverde Vera v.1, and my Iconia A500 tablet does not like my other wireless router)
... and have LinuxMCE do DHCP for anything connected to IT for internet and internal cross talk?
There is magic involved with this (meaning I cannot explain why), but if you have multiple things spitting DHCP attached to lmce, odd behavior ensues. It creeps through wan ports... it tunnels through things I do not understand it to be able to in an attempt to find life. It is very greedy and prolific.
I know my Linksys WRT54GS running Gargoyle can be set to allow for other DHCP connections,... and turn off DHCP.
I don't know how easily the Vera can be configured to do the same.
Until I get a chance to reconfigure the network, Vera connects first, then the other router to it, and currently then to all other machines including my LinuxMCE Core.
I briefly tried; Cable modem to LinuxMCE Core to Vera to Linksys, but everything lost its Internet connection but the Core (The Vera may have been running DHCP, but the Linksys had it turned off).
I intend to move my Gargoyle-powered router inside, with LinuxMCE sitting between the Vera and the Linksys. So, it would be; Cable Modem to Vera to LinuxMCE Core to Linksys/Gargoyle router (with DHCP turned off) to everything else.
Will the above work,... or do I have to get more aggressive with the setup of the Vera?
Vera is pluto. Putting them both on the same wire, they are gonna bump heads. Tkmedia has the two playing nicely I believe. He will have to give you more details. It will have to be a very non-standard configuration.
I do not personally see the point in having both plutos, and hiding off things from DCERouter is counterintuitive to me... LMCE cannot take advantage of resources on the machines, and you cannot control LMCE through those interfaces. It is designed to just integrate everything seamlessly. You are a grown up, and can use your equipment however you see fit obviously... I am certainly not trying to get into anything by asking... but why do you want to compartmentalize something which exists to provide layered transparency?
