Emule On Dtac: Ports?

[motorpsycho]

hi,

i'm running emule on my laptop using my windows mobile phone as a modem, works fine so far.

but what ports should i configure to avoid the low-ID problem ?

If you're having trouble then you might try port 80 as it's possible they've blocked all non-standard ports. Enabling 'protocol obsfucation' might help as well.

thanks laawman, i always connect to server with obfuscation, but i forgot to enable that in options too

i was also thinking about port 80, tried that and got the message "your port 80 is not reachable" from the server.

i created a new rule in my firewall and also temporately switched off my FW, still i have a low ID .

when i dial in, i see "opening port"..."dial #99*"....but i don't know which port is opened, couldn't find anything in "modem properties".

so if anyone can shed a light on this...tia

Most mobile connections (AIS for sure, Dtac most probably) will assign you a private IP address and not a public one!

Which basically means you are invisible from the internet, so you'll always be stuck with a low ID!

DTAC also. In my case the 192.168.x.x. range of private IPs.

thanks for you answers.

does this also explain why rapidshare told me "you are already downloading 1 file" when i wasn't ?

do i share my IP with others ? that wouldn't be exactly private or ?

Just try to visualize it in the following way.

Imagine you have a small network at home with 5 computers and 1 internet connection.

You have 1 modem (router) connecting to your ADSL line, and it will get 1 public IP address from your ISP (public means an IP address reachable from everywhere on the internet), and your router will distribute 5 private IP adresses to your 5 PC's.

Your 5 PC's are invisible on the internet, the only thing visible is the public IP address of your modem/router.

Your router will do something called NAT (Network Address Translation), which means if PC number 2 requests something from the internet (e.g. a website), then it will fetch this website from the internet, and send it on towards the PC which requested that website.

As far as the internet side is concerned, it only knows the modem/router requested a webpage. It has no knowledge of the PC's behind your router.

Now imagine Dtac being your modem/router and your mobile phone will be one of the 5 PC's.

Now if rapidshare tells you you are already downloading a file, it will only mean that one of the other 5 mobile phones (most probably somewhere in the same area as you) is also downloading something from rapidshare. Rapidshare can only see the (public) ip adress from Dtac, it cannot see the mobile phones behind Dtac! Additionally, in Dtac's case it's probably much more then 5 mobile phones hidden behind one public IP address.

If for example e-mule tests a port, it can only test a port on the public IP it sees, which will be the Dtac IP address. Dtac will have no idea to which mobile phone to send e-mule's request, since none of the mobile phones requested something!

In your home network you would have the same problem, since e-mule would only see your modem/router, but none of the 5 PC's behind it. In this case however you can solve the problem by doing something called "port forwarding". Doing this, you will tell your router that any request coming in on a certain port, has to get forwarded to for example PC nr. 2, even if that PC never asked for something. So suddenly e-mule can reach that PC (as long as it makes the request for the correct port, the one you forwarded).

Unfortunately, with Dtac, you do not have the luxury of accessing their systems, so there is no way to tell Dtac that any incoming request at a acertain port has to get forwarded to you...
