Hi TKaiser / Igor, FYI i manually prepared a patch for devices that use rtl2832u that i think may interest you to add this patch to the build process. You can patch against legacy kernel 3.4.111 and give users a chance to get their device recognized. Sorry, i can't couple with the automated armbian process yet, i usually do the things manually. I hope this can be useful (and hopefully works for someone). clone here: https://github.com/avafinger/rtl2832 @lex

Hi, It is nice to join in and be part of a such fast growing UOS. I would like get some advice and solve the following scenarios: * Internet Sharing with one Client only, no 'switch' needed, this has been accomplished with the instructions in https://wiki.archlinux.org/index.php/Internet_sharing, so all the iptables rules and NAT is done with success. I am able to navigate the internet from OPI-PC. * which armbian version for the smallest server to run on OPI PC, that will provide some web services. * Need to be able to access OPI-PC from the external world (from PC-3), this is what i am struggling to get it right. Say i want to connect to OPI PC from a browser: http://200.xxx.xxx.xxx . Things to be noted: * don't worry about the router, this has been done also, * please, don't try to solve the puzzle changing the topology (drawing below), i know the way you would possibly use OPI2 Plus would be the other way around, use it as a Wifi AP and connect the eth0 to Internet, but this topology is so to solve a specific problem, * the NAT rules must not interfere with the currently running rules, * must find OPI PC in all ranges (from internal 192.168.xxx.xxx and from internet) * wlan0 is using DHCP, need a way (or script) to find the acquired IP, and it may change very often. This is being challenging to get the rules to work since all possible samples i find is using a static IP, if the rule must have the IP i need a way to get it (whenever it changes), * will use Ubuntu 14.04 LTS for personal reasons, but i think iptables is Distro agnostic, * i will share all the results in case others want to learn from this, * i don't use FW, only iptables. * be kind, i am not very keen on this iptables stuff, In summary i have internet sharing from the OPI-PC but can not access it from outside. Here is a drawing of the complete topology: +---------> eth0 PC-3 | v Internet (public IP) ^ | | v IP: 200.xxx.xxx.xxx [ Orange PI 2 Plus ] [ router ] <-------> wlan0 (DHCP: 192.168.254.13) ^ eth0 (static IP) <----------> eth0 [ Orange Pi PC ] (small server serv.) | 192.168.0.77 (static IP: 192.168.0.1) | | | +-------> eth0 PC-2 (IP: 192.168.254.55) I would appreciate if you could help. @lex Ps: Focus on OPI2 Plus, don't care about the internet sharing.
