You could _perhaps_ hold that case for a ***peer-to-peer*** application.

Opera is a Web browser. There is no such things as "NAT traversal" problems

when it comes to HTTP (because HTTP is _the_ most basic benchmark for a NAT

device).



Any HTTP client that ignores the policy table in any way, such as

by forcefully trying IPv6 before IPv4, is just plain BROKEN.



Same thing for POP, IMAP, SMTP, IRC (let alone DCC),

FTP with EPSV, XMPP or any other client-server TCP-based protocol.
