Hi, Eric.

I assume you've confirmed that it works if you turn off the Linux
machine's firewall?

Also, is "128.3.128" a valid network IP address?  I don't do a lot
in the firewall space, but I feel like I usually see that written as
"128.3.128.0"; does that make a difference?

Lastly, and this is more of a hijack of your thread (sorry), but the
first rule is saying to accept any UDP packet from the specified network
with a source port of 5064.  That means an attacker can connect to *any*
UDP port on that Linux machine as long as their source port is 5064.
That seems pretty lame.
