PHPBB3 all users have the same IP [Answered]

Hi Team,

Using latest XAMPP install for win32
OS: win vista 32
internet connection: ipv4 behind ISP's NAT (i have a local 192.168.x.x address)
How users can connect since I can't port forward: Using ipv6 broker tunnel from freenet6 (users use http://mydomain.broker.freenet6.net to connect)

Everything working fine except that all users on my forum have the same ip, actually the ip of the host computer(ipv6). PHPBB support suggests that it's not a problem of the board but a server issue, they said the server is masking the ip add and not relaying the correct ip. Can someone point me to the right direction? I have already tried my isp, freenet6 and phpbb support but no luck. Maybe someone has already gotten in this kind of situation, I just want to hear more opinions on how to go around this issue.

Thanks!

"How users can connect since I can't port forward: Using ipv6 broker tunnel from freenet6 (users use http://mydomain.broker.freenet6.net to connect)"

read that carefully -- effectively, its a proxy - (clue)

OK , are you ready? LETS PLAY IP JEOPARDY with your host AlexB!!!!

hushed voice...
Its the IP address of the intended recipient of the datagram when you use IPv4 to IPv6 tunneling

... JonB plays the Jeopardy 'timer jingle' do do do do dut dah da do do do do (written BTW by the show's producer Merv Griffin!)

<BUZZZZ>
#3!

"What is the IP of the tunnel service?"

... dramatic pause ...

That's correct #3, you have just won this round of IP Jeopardy - The closed loop for the Ultimate GeeK

"My" network engineering perspective is that the only IP that the server (and thus PHPBB) ever sees is the IP of the 'tunnel' - otherwise it would attempt to forward the traffic to the 'true IPs' of the clients. The return traffic 's destination has to be the tunnel... (which in this case is also your local machine) Thus all your 'clients' have the same IP.

Thanks Jonb for enlightening me in this issue :) I'm not a computer expert but I understand most of it, well almost hehe. From my understanding, it would be really difficult to extract the ipv4 address of a client from an ipv6 tunnel... if not impossible. So it's either i stick with ipv4 or they all go ipv6 :)

Thank you for the reply, I know this is my first post so I really appreciate it :)

@boybastos -

That is it in a nutshell - good job...

Good Luck
