ok now look, i had a shiro modem from ptcl. this modem has also the problem of manual portforwarding in a long procedure. because it was not in the list of the routers of this site
www.portforward.com.but fortunately, ur router or modem is listed in this list.
So now , first open this site
www.portforward.com, and here u will see a big list of routers. Now Select ur router.an advertise will come but skip it. then it will ask u t\that which program do u want to portforward. Select utorrent. Now a guide will come. that's all do what the guide tells u. OK
i had many problems in it. that's why i have changed my modem from the ptcl. had to pay 2000rs for changing. and this modem is awsome man. it automatically portforwards. No problemo. hope that ur problem will be solved.
Asal men agar tumhara shiro ka modem hota to men apne bhai se poch kar step to step khud hi bata deta lekin i have no experience in this modem. that's why i have done little search for ya.
