[TriLUG] OT: DNS not following routes [Solved]

[Brian Henning]

I futzed with a couple things; the combination of these two changes is 
what made it work:

- Tell the client machine to use the router between A and B as default 
gateway, instead of the gateway on the far side.  (Let the router figure 
out where the packet needs to go next)

- Add explicit FORWARD rules to said router to allow UDP port 53 data 
through (dport = 53 for queries and sport = 53 for responses..  probably 
should tighten it some, but it's not a perimeter firewall).

Thanks for all the input!
