Well, yea, but I wanted a good number to bake into the build = which I'm hovering over the build button for...

=A0

Two questions:
1. What do you want lab.projectbismark.net pointing to? =A0I'll update the dreaded= godaddy until DNS lands.

A problem is that the ro= uters register themselves in DNS (or will), and we need bind9 for that.
=A0
I hope to have real dns after meeting with netops monday.

2. How do you run the babel multihop stuff? =A0Can I run it in this build? = =A0I'm in a fairly big house with *zero* wireless connectivity downstai= rs and would like to try it out.
I would like =A0Host <----wireless----> WNDR Relay <---wireless--&= gt;WNDR Relay <---wired ---> Modem
Not sure how to set up the relays.

Yes, you can do= that. I'm tickled you're willing to try it...
There are a coupl= e ways, but I'd prefer to get you through it in irc?

=A0

Thanks,
-Nick
