thanx APPUS...
but 1 thing APPUS...i never confg port forwarding for my torrent client. but still i m having 270~300 KB/s download speed .. is there any thing to worry abut??
In torrent client (utorrent?) , can you see a green checkmark or an yellow one(asterisk) on the bottom ? If it is green, somehow it is forwarded(DMZ'ed to your pc). If it is yellow, nothing to worry. You may get even better speed by doing port forwarding
may b since i have selected "allow" opton in global control of the
router's default access rule..help says "If user selects "allow" as the default action, the router by default will allow all types of application at any time to access the Internet."
better you do everything manually in router. you may have max less than 10-15 apps need to connect right? and out of that, many dont need port forwarding.
also APPUS as u mentioned abut DMZ ... i m still not clear abut DMZ. that is, since ip camera or
printer in ur case is in local network i.e maybe in the range of 192.16.2.x ....when usng //ip or //yourhostname.dyndns.org , how can i access ip camera... my pont is shouldn't there be a wild card entry...i.e x.yourname.dyndns.org ?? or m i wrong abut wild card... correct me if i m wrong pls.
Port forwarding is always a better option unless you have everything to control (like internet security /firewall correctly configured)....
Port forwarding: it forwards only the particular port we mention !
DMZ : demilitarized zone, forwards everyports to the computer on the ip we specify.
When to use portforwarding: If we know which port to forward and less application needs port forwarding...
eg: torrent, ipcamera
When to use DMZ: We dont know which ports needs to be forwarded and many application needs to access your pc !
eg :Ftp server, webserver, remote applications, sql server, and many other.. (ie, if you have a huge list) Remember: you can still use Portforwarding if you have time to enter all the port details !
In your case for torrent, ipcamera, even two three applications, you can use portforwarding !
when u use http :// yourip, by default, it searches your port 80 (normally webserver, router) (if you have an option to configure, then router will be 8080)
So, if you forward to any other port, you have to mention in the address as i mentioned in the previous post ! ( : & port was together so it became

, that was due to my carelessness)
it should be http :// yourip: port or http :// hostname.dyndns.org : port
Remember: if you dmz, you give ip instead of ports. so, if someone try pinging to your web ip 117.x.x.x , it pings on your computer. If you do portforwarding , it hits on the router and bounce back. (unless correct port is mentioned along with ip)
i feel port forwarding method will be safer i case of ip camera..which method have u used for ur printer??
always use port forwarding ! I had
windows firewall on, norton internet security firewall on, so i DMZ to my PC with portforwarding one port to printer... (was almost 3-4 years back)
I was running many application that time..
Audio streaming, video streaming, ftp, http, sql, mIRC, torrents ,
Microsoft remote desktop (MSTSC), RemoteAdmin... etc.. etc........
HAPPY DIWALI to all my friends out here
