Unlikes magic-wormhole or wormhole-rs, there is an issue with
wormhole-william, where it fails to establish direct p2p connection
between sender and receiver.

Receiving side has IPv4 and IPv6 public addresses. Sender is behind IPv4
NAT.

magic-wormhole and wormhole-rs work fine, (in any combination of sender
and receiver), and easily get 200MB/s due to proximity of client and
server (1.16ms rtt), but using wormhole-william, it always goes via a
transit server, (aka transit.magic-wormhole.io aka 45.33.13.8), which is
somewhere in central US, where in my case both sender and receiver are
in central Europe (134ms rtt from either sender or receiver), explaining
speed too.

As far as I can tell, this doesn’t seem to be specific to the Debian
package. Therefore, could you please raise an issue upstream at
https://github.com/psanford/wormhole-william/issues?

Thanks,
