Note that Avahi is not intended to be used in ppp links, but only on
LANs. 

If you emply NAT then it's the job of the NAT router to translates
packets properly, not of the applications. That's the whole point of it
in fact... If you really want to use Avahi via this vpn link, then the
right fix is probably to add special mDNS translation support to
iptables, similar to the existing support for FTP.
