Hello everyone,
I'm behind one of the unfortunately famous DS-lite IPv6 ISP in Germany, where no real IPv4 is available, which makes it is more than difficult to route back to my LAN from outside. I'm stuck in "Phase 3" which should be a simple one among this complicated attempt to get Asus OpenVPN server running for this purpose.
My setup consists of the ISP modem/router, plus Asus right behind serving my LAN. I hope that this in the end can turn into a tutorial for those facing the same problem, So some details below.
Phase 1. Confirm Public IPv6 at Modem/router 'ping' from outside LAN, plus same for Public IPv6 of the Asus router -> DONE
Phase 2. Setup portmapper service on the web to go from IPv4 to IPv6 port, towards the Asus router. IPv6 address -> DONE
Phase 3. Open port on Asus router and confirm via IPv6 port scan http://www.subnetonline.com/pages/ipv6-network-tools/online-ipv6-port-scanner.php, that the port is open from outside LAN. -> NOT WORKING
I'm really stuck here where I was expecting no complications, and cannot move forward to proceeding with the OpenVPN server where I expect more IPv4/6 port issues. Really stuck, means 4am yesterday, without any success. I'm really confident some of the more experienced minds in this forum can help out with some smarter ideas I might be leaving behind. Thanks a million in advance.
BTW, the same Asus router is acting as an OpenVPN client to an outside server. I don'T think this should be an issue overlapping in some way what I'm trying to achieve, since I also tried with the VPN client OFF.

- I have allowed traffic on all ports and disabled the firewall on the ISP router to the Asus.
- I have disabled the ISP IPv6 FW (for testing purposes)
- I have disabled the Asus IPv6 FW (for testing purposes), I have also enabled it and added a rule for the
- desired open port for the Asus IPv6 own address, but did not work either
- I have included the following IP6TABLES line in the firewall-start script:
ip6tables -I INPUT -p tcp --dport 6100 -j ACCEPT
