port forwards should listen on localhost only

Hi,

my port forwarding listens on all (*) interfaces. Is it possible to limit it to localhost only?

Cheers,
Torsten

I fear this is not possible. The current NAT implementation is a complete user-space implementation which uses sockets to emulate TCP/IP connections.

Yes, I see that src/VBox/Devices/Network/slirp/socket.c has a line

addr.sin_addr.s_addr = INADDR_ANY;

in function solisten() and that seems to be the problem.
