can't connect... |
|
|
I have an XP SP2 machine(m1) trying to connect to an XP SP2 machine(m2).
m2 did the checkip.dyndns.org thing and got several ip's back ( i didn't see
the output)
m1 did get one ip back from checkip.dyndns.org
m2 can ping m1 but never connects when placing a call to m1's IP
Is there a NetMeeting for Idiots that walks me through this one step at a
time? A pointer to documentation or suggestions on next steps would be
greatly appreciated. |

I am not sure about the "several" ips -- I am guessing this is at different
times?

I haven't used checkip.dyndns.org before but a quick check seems to
indicate that it provides the "apparent" IP of the user. If you or the
other party are behind a router/border firewall or other NAT device the IP
shown will be the public IP of the device.
The help about of NetMeeting provides the local IP of the user. Generally
if the "apparent" IP of the user and the NetMeeting provided IP are the
same, the user can be called using that IP as the address. If they are
different (the local IP will generally be a "private" IP -- 192.168.x.x,
10.x.x.x, 172.16-32,x,x) the user can only be called using a
gatekeeper/gateway device or by using the dmz feature of the router (and
then calling the public IP of the router -- the one checkip.dyndns.org
returns).
If the caller is also behind a NAT device using the dmz on the calling side
will likely also be necessary to get full function. |

Would the gatekeeper/gateway device be the same device I use on my local
network (03 Server network at home) to access the internet? Thanks Brian.

No generally it is a separate server. Do you have a router/gateway device
or are you using ICS or other software router?
As I recall software routers usually do not have the kind of pass thru
function (dmz) required. |

Does the server provide some internet service? Likely it would be better
placed behind the router with the router connected to the modem with
appropriate ports forwarded.
Regardless it will likely not be possible to call through the two NATs
(either way) using NetMeeting. I don't believe ICS ( providing NAT on the
server) has any mechanism like the dmz feature found on most routers.
If the server was behind the router it would be possible to use the dmz
feature of the router to forward to an internal client and have NetMeeting
function at that client (assuming the dsl service itself is not NAT'ed). |
