A possible option would be to setup an OpenVPN tunnel somewhere to go through. Maybe not pretty, but it'll work. If you want to try that email me off list and we can set it up on my colo box. -brian On Aug 6, 2012, at 16:00, Sampsa Laine <sampsa at mac.com> wrote: On 6 Aug 2012, at 20:07, Johnny Billquist wrote: Ah well, I could go on... Suffice to say that it's not because I'm opposed to the features that a TCP connection, or DNS resolution would give, but I prioritize something that I feel confident is working to features. And doing a proper solution with all these aspects is more work than I have cared to put into it. The bridge program is a hack. As Paul mention, pthreads would probably be a good start if you want to do something more intelligent. You need to start thinking asynchronously. My desire for this is basically because my ISP is NAT'd to hell - I have no way of getting UDP packets back to my network, as the ISP gives me a non-routable address. Why go with this ISP? Well it's about 3x faster than the DSL I can get in the sticks over a 3G signal, with unlimited bandwidth and usage. But sucks for HECnet.. Sampsa
