Hi All: My app is to simply fetch files from a web server behind a NAT using a specific REST API. Using the sample app, icedemo.c, I have experimented with punching the holes and then setting up OpenVPN tunnels. That was fun, however I have a few challenges to still overcome and need your help.? 1. OpenVPN is not available on all platforms (especially the iPhone) 2. I need a reliable transport (http/tcp) over the ?UDP ports that ICE has given me.? 3. I also need it to be secure. I see that other efforts such as libjingle and libnice have a pseudo-tcp-over-udp implementation. I have invested many many weeks already on pjnath/pjsip and like it.? Has anyone implemented a secure pseudo-tcp over udp with pjnath/pjsip? Any pointers? Thank you Auro -------------- next part -------------- An HTML attachment was scrubbed...
