[mythtv-users] Multiple boxes on different networks

Thanks for the tips!

Kevin,

I looked at the MythTV documentation you referenced. Thanks - I forgot about
that snippet.

Looking at my installation, I can't find the mysql.txt file, or anyplace
where DBHostName is set. I did try turning off mysqld temporarily
(/etc/init.d/mysql stop); unfortunately, mythfrontend and mythtv-setup did
not like that too much when I restarted them. I will have to look into this
further.


Chris,

You described your setup as having a mythbackend server that also happens to
be your router. Does it communicate with other MythTV equipment on the
192.168.0.0/24 interface, the 192.168.1.0/24 interface, or both? Is this the
master backend? the only backend?


Lucas,

I should have clarified that both hosts can see each other without any
difficulty. I'm able to ssh/telnet/etc. from one to the other. Well, at
least one way. Going the other way, I'm able to as long as I have the router
forwarding the appropriate port.

In case you're wondering why I have the NAT, I plan to use the 192.168.1.2
host to capture packets using NCID
(http://www.davidlaporte.org/tutorials/ncidsip.php). As long as it's sitting
out there, I thought I might as well use it to as a backend and frontend _if
posssible_.

and

I think I have the different subnets set up. How do I route all traffic
between them. (You mean without forwarding ports, correct?) Does this
involve modifying the routing table on the host(s)? the router?

> Also, make sure your subnet masks are correct. the 192.168.0.0 is usually
a

properly.

If I can ping/ssh, then packets are being routed properly, correct?

This is the gateway, correct?

and

So what you're suggesting here will allow me to have the separate networks
without NAT?

Thanks for the help!
