Netgear DG834g PORT FORWARDING!! AGHH!!!

Hey guys,

I have a Netgear DG834g ADSL Router, and I am trying to run a program
that requires port 6969 to be open. I have followed what Netgear has
told me to do, open port 6969 in services and add it to firewall rules
and all that jazz, but then when I open the program and type in my
router's IP address (which is 81.86.85.62) and add on ":6969" (so it
would look like this 81.86.85.62:6969) it will not open!
However, when I type in the following IP addresses it works.

localhost:6969
192.168.0.2:6969 (my LAN IP address)

I have also got a backup ADSL modem (Alcatel Speedtouch 330) so I used
that and when i typed in the IP address given to me when I go to
ipconfig /all in DOS with :6969 on the end (61.152.168.23:6969 [not
the ip used, just as an example]) it worked perfectly!

I have no clue what the problem is and I'm sure a lot of other Netgear
users would like to figure out this problem as well.

Here are some specs that may be needed.

ISP : Pipex
Down Speed : 1024kbs
Up Speed : 276kbs
Router : Netgear DG834g

Computers on the network :

2 Pcs Running Windows XP Pro SP1
1 iMac running Mac OS X
1 eMac running Mac OS 9

Thanks a lot, any help appreciated!
Cameron

You cannot access the server by using the WAN IP address you have to use
the LAN IP address(see your manual for "Considerations for inbound rules")

What do you mean by the WAN IP address? thats the only one that is
displayed on the router setup page when i go to 192.168.0.1!

btw i maybe didn't mention im not using wireless on this router, i'm
using the ethernet

I was referring to the Wide Area Network ,in this case the IP provided
by your ISP.

Here is the page that I see on the router status page.

I cannot find the IP Address that you are talking about!

The first one: 81.86.x.x

When you set up port forwarding, you are defining an address (and possibly
port) translation. For instance, if you forward port 6969 to
192.168.0.123:6969, you are basically saying to the router "When a packet
arrives at the WAN side with address 81.86.x.x and port 6969, translate the
destination address and port to 192.168.0.123:6969, then forward the
packet." (It's actually a bit more complicated than this, but the details
don't matter.)

Given this, it should be obvious that if you send a packet to 81.86.x.x:6969
from the LAN side, the translation will not be applied: the packet does not
arrive at the WAN side. You must use the LAN address, 192.168.0.123 in this
example.

BTW, hiding the MAC address of the ADSL port isn't necessary. I know what it
is anyway (it doesn't take a genius to figure it out), but it's of no use to
me. Likewise the ATM VPI and VCI, which are the same for everyone.

I have given this ip with port 6969 open to a friend outside of my LAN
and still it will say that the connection has failed.

here, try it for yourself.

81.86.234.15:6969

And then when i type in 192.168.0.1:6969 (which is the gateway ip)
like you told me, and it comes up with the same message.

yeah i realise now there wasn't any reason to blur out the stuff i
did, im just paranoid
xD

Seems to time out. If port forwarding is set up correctly, the only reason
for this I can think of is a firewall on the machine the port is forwarded
to.

Sorry, by "LAN address" I meant the only LAN address I mentioned - the IP
address forwarded to - not the router's LAN-side IP address.

As of 1050 this morning 81.86.234.15 is an "APACHE" web server site.This
would indicate your ISP has given you a Dynamic IP rather than a Static
one so there is no real point in giving this address to anyone.
As long as you have set up 192.168.0.2.6969(the original IP you quoted
for your machine NOT THE ROUTER) in your BT program it should work.
