i didn't follow appus's suggestion
yup whitestar did point to me one thing that you dont need static IP
for port-forwarding........and that was really helpful.
I didn't even disable DHCP!!!!!
its enabled with start IP address as 192.168.1.2 and end IP as 192.168.1.254
but still I have done portforwardingsuccessfully.....
and everytime I check with IPCONFIG
my IP address shown is 192.168.1.2!!!!!!!!
I dont know why it is always that..coz it should change as DHCP is enabled.!!!
When I checked and found to have 140 viruses........it was with
AVG 7 free edition..........
Now I use AVAST ANTIVIRUS 4.8 HOME EDITION.........
what antivirus do you use?? and do you advise me to install any personal firewall.........when there already is a firewall supplied by BSNL??
do I need any more security for my open port???
I dont think so.......coz It's impossible to knwo a port out of about 60000!!
and my IP is always changing........what do u think?
YUP your right superprash..........
but I thought hard and decided to post my internal IP
it doesn't matter........and I have also changed that now......

Congratulations ridam on successfull port forwarding....Actually its not needed to disable DHCP in order to port forward coz when ever the router boots up,it assigns ip address from the DHCP pool and in most cases this is done based on the interface,ie, for example if you use a wifi enabled router, the first priority will be to the directly connected system and then only to wireless network. So the first ip will be assigned to the pc that is directly connected to router and then only it assigns remaining to wifi enable pc's. And this is regarding your private IP....
There are 2 kinds ip addresses public ip addresses and private ip addresses, public ip addresses are those ip addresses which can be publicly routed(example internet) and private ip's are those ip's that cannot be publicly routed(example a LAN),so if a router is in PPPoE mode rather than bridge mode,it will have 2 network,one will be routed to internet and other to LAN,and wat you see on your system is your LAN ip and wat you see on the routers WAN interface is the WAN ip that is assigned by your isp.
Public IP's cant be changed by user,while we can change private ip address. This method of mapping public IP to Private IP address is known as NAT(Network Address Translation),this also provides more security than unNATed network since an outsider will not be able to access the pc or computer inside this NATed environment....and for this purpose only we are using port forwarding....I think i would have confused you by telling all these things...Sorry if I did...
I dont know much about Antivirus softwares but if you are looking for an efficient Antivirus s/w then you can go for kaspersky or nod32....but I use symantec antivirus, it has the same scan engine as that of norton antivirus and consumes less memory...
Hope this will find useful to you....
Have a nice time....

thanx Bobbythomas for providing with that info...........
although I knew the difference between private and public IP address........
that was really helpful.............
my modem is SL2_141 wireless type II modem......so it has that wifi thing you were talking about.......
but I dont think I can use Symantec......coz my OS is WINDOWS 98 SE.........
onlytest.........actually my computer's lan settings's are like that only!!!
whereas I use a fixed DNA server
IP address box is same as given in the snapshot>>.....ie no fixed IP's for lan........
still portforwarding works!!!
:thumbsup:

:thumbsup:@/members/ridam/Will be very much helpful to other users, if you can post the screen shot/s of the modem pages for setting Port Forward. Please confirm you accessed the Advanced settings of modem/router from the "update software" menu or otherwise. You can blank any IP details, as you wish. Thanks.
Changing to Bridge mode is not an option as I prefer PPPOE mode due to
firewall provided automatically by BSNL and much more security...
and last time when I was in BRIDGE mode.......I had 140 viruses in my computer!!! but now I have none....so
Is it true that PPPOE mode is more secure ? For all I know it is actually less secure bcoz your username and password is in the router[ instead of your head] and thus your account is easier to hack into.
I use bridge mode myself and have not had a single virus infection since I switched to broadband. (I use avast! antivirus and comodo firewall 3).

i agree with you. no problem since april 2006 (my first bsnl broadband connection)

"In siemens SL2_141 modem type II wireless" router homepage
ie..if u type
192.168.1.1 in the URL
the modem home page will come up......but
.there's no tab or button through which portforwarding, Nat..Virtual sever........and DMZ.etc could be accessed............so you have to use either hyperterminal or telnet..........for port-forwarding.
I used hyperterminal..........
