I have a DO application that works pretty well on the network. But
when I try to reach someone with a NAT or a firewall, I can't get the
connection to the distant object. Is there any way to circumvent that
?
Any of the normal ways for resolving such issues; i.e. opening ports,
redirection, etc. DO is inherently bi-directional in terms of
connections; you can't use any sort of "passive" mode. You could do so
if you really needed, but it'd mean writing your NSPort subclass to
replace NSSocketPort, which is very much a non-trivial exercise (one
example can be found at
<
http://www.sourceforge.net/projects/securedo/>, which I wrote).
DO doesn't support any proxies of any sort (e.g. SOCKS, HTTP[S], etc).
The closest you could probably get with any ease is to take the
aforementioned SecureDO, which adds SSL support to DO, and modify it to
support a HTTPS proxy. Of course, most HTTPS proxies won't connect to
any port other than 443, so you'll probably still be stuffed, if that
even works for your situation anyway.
