I got ustarcom ut300r2u router which has a custom bsnl rip firmware
which does not include virtual server option and only includes NAT-DMZ option
Now here is my problem...
1. My router is on pppoe mode and did add my lan ip(network connection -> Local area connection ->properties ->tcp/ip etc etc..) in the dmz
but even then using GRC scan/canyouseeme i am getting all my ports as closed... :nono:
2. Then i put my router on bridge mode so that it can bypass the router firewall and then i did the scan again but still all ports shown as closed..
3. Then i turned of my windows firewall and did the scan again and found that only port 139 was open... i dont know how the hell it was
4.One of my friend Has airtel broadband with beetle220bx router which as Nat ->virtual server option, so i borrowed his router and reconfigured it for bsnl(vpi/vci 0/35 etc etc)
and i was able to connect.
then i did the scan again and to my surprize i found port 80(http),21(ftp), and one more port i dont remember now..
was open.
then i added ports in virtual server to forward them and did the scan but my ports were still closed
(port 139 on ut300r2u and ports 80 ,21 open on beetle 220bx Open w/o doing anything in the router)
3. One last question.... letz say If I am running a program on my computer that connects some "xyz" server which infact tries to connect me through "so and so ports".. and if those "so and so ports" are closed should the connection be terminated?:surrender:
