It's the other way round: You're capturing the quotes in $a so the shell
will pass them to the command after expanding the variable reference.

Your test-script is simply broken. Instead of 'iptables-translate $a',
call 'eval "iptables-translate $a"' and everything's fine. You did not
try calling iptables-translate with given parameters manually, did you?
Please keep in mind that the first step after writing a test script is
to debug the test script itself.
Cheers, Phil
