So obviously you can't use a DHCP server to assign an IP address to the interface that the DHCP server is supposed to be listening on. But that's what this configuration seems to be trying to do. You should assign 10.99.0.1 to eth0 in the normal way (whatever that is for ubuntu) and leave this section out.<br>

</div><div>I assume "option routers" is setting the gateway on the client interface. But the client is not going to be able to connect to 192.168.2.2 - it's not on the same subnet and there is no router or anything to help. This should be set to the address of the myth box on that subnet, i.e. 10.99.0.1. If the hdhr needs connectivity to the rest of the network then you'll need to do some iptables config on the myth box.<br>

If you run your own DNS servers like I do, then<br> use their addresses. Otherwise, find out the DNS servers that your<br> ISP provides and use their addresses. They will likely be stored in<br> your Internet router somewhere, and your ISP can tell you if they do<br> not have them listed on a web page. You can easily find out the<br> primary address by just doing a command like:<br><br> nslookup easynews.com<br><br> The address in the "Server:" line of the response is the primary DNS<br> server you have configured. There will usually be at least two DNS<br> servers though, so it is best to have both listed if possible.<br><br> Note that the "options domain-name-server" line is not necessary for<br> your HDHomerun as it does not do DNS lookups, so you could just<br> comment out that line too.
