As JJK pointed out, what is the reason to have 2 tun devices.

Whatever, you need to verify first that routing to your DNS server, e.g.
 74.207.241.5 is set up correctly. Then you need to make sure the DNS
request can be answered by the server, e.g. the server either has a
route to the requestor or the request is NATted.

Please check your interface pointing to 74.207.241.5 and use tcpdump to
see how the request looks like. If it still has an source address of
10.8.0.6 then the odds are high the server does not know how to reply to
this request. Once you have this issue resolved you can use the same
aproach to find out about your ICMP packets

cheers
