dyndns by bluetooth

I have configured connection properly through mobile phone (SonyEricsson C510) by bluetooth. I get dynamic IP address and can ping everything but can’t ping my IP adress which was automaticaly granted, from outside. SuseFirewall is stopped. Anybody knows where is the problem?

Thanks for help.

Please provide more information. To what system is your mobile phone making a connection. What IP address do you get? How is that system connected to Internet (via a NAT server?), etc.

Ok. My laptop with Suse 11.2 bind mobile phone via bluetooth to ISP. It get dynamic IP for example 10.72.28.167 on modem0 and everything is right. I can ping and browse internet. But I want to go to my laptop, to 10.72.28.167, from internet. Firewall is deactivated but can’t ping 10.72.28.167 - host is unreachable. Maybe the service by bluetooth goes in one direction…

Seeing that yout IP address is a 10.x.x.x, this means that you can not reach that address from the Internet. The 10-network is a local network. This means that you must use a NAT server in between your mobile phone and the Internet. From the name of your network interface modem0, it looks as if you are using a dialup connection. Does that interface gets a global IP address? Use

sudo /sbin/ifconfig

to find out that IP address and report back.

that is a “private IP”, it doesn’t exist on the internet…only on your
machine…it is the (lets call it) “local IP” your router (or wi-fi)
uses to communicate with your machine…

when you browse the internet then you (as 10.72.28.167) contact the
router, wi-fi, modem, whatever which then connects to the internet as
whatever its ‘real’ ip (external IP) is…if you go bluetooth to a
phone which rings up an entry point then the ISP temporarily uses one of
its assigned ‘real’ IPs to conduct the back and forth between the ISP
and the distant node…when it gets and answer back, then it sends it
to you at 10.72.28.167…

go here http://www.nirsoft.net/show_my_ip_address.php and you will see
the ‘real’ IP being used by your ISP…

and, i guess you can ping that IP…but, i think it will be your ISP
answering the ping, and not your machine (but i’m not sure)…

by the way, i recommend you turn you firewall back on…especially since
you are running 11.2 which has passed its end of life and has received
no security updates since May 12th of this year
