Ok, I need to simplify this. I need help, I don't know what I am missing. Is 
anyone able to recreate the following netcat test?

I cannot seem to get the DNAT portion of the iptables to work at all. Here is a 
very simple test:

On the proxyvm, I use the following rules to redirect port 5353 to localhost, 
and allow the connection:

iptables -t nat -I PR-QBS 1 -d 10.137.4.1 -p tcp --dport 5353 -j DNAT 
--to-destination 127.0.0.1
iptables -I INPUT 1 -p tcp --dport 5353 -j ACCEPT

Then, on the proxyvm, I run the following command to listen on that port (no 
other service is running on that port):

nc -l -p 5353

Finally, on the AppVM, I run the following command:

nc 10.137.4.1 5353

My expectation is that the two netcats will connect, however they don't. What 
do I need to do to get my AppVM to talk to my ProxyVM? Thanks
