Netgear MR8v14v2 - portforwarding would not work ?

hi,
i just bought a netgear MR814v2 router ( wireless and 4 ports ) . I have verizon dsl and everything is working and the steup was good. Although i am not a networking genius or anything but i am sure i have the port forwarding setup right for both ftp and http. Two issues :

1) No matter what, i have not been to get FTP to work. It just would not log in when i try the ISP assigned IP. It does work for internal 192.168.*.* IP.
2) Http , i haev Apache running. When i type 192.168.0.2/mypagename , it goes there but VERY VERY slowly. When i try and access it via IP address assigned by the ISP then it does now work.

I am not sure how to debug it or go about it. Any help is appreciated . thanks
 
I assume you are hosting from home. If so...check to see if verizon is blocking any ports. I know my ISP blocks the standard FTP and HTTP ports...
 
I was poking around that exact router the other day and I think I saw a feature for DMZ. If that router does have this feature, you will want to just put in the IP of the FTP server and have it work through that. Getting FTP to work through NAT any other way can be a SERIOUS pain because FTP uses the port you set (normally 21) for control traffic such as commands, directory listings, etc. The port is uses for the actual data transfer is totally seperate and can hop around based on some algorithm I read a while back (sorry for the lack of detail there.)

Just be sure that if you do go with the DMZ option, you turn the DMZ back off when you're not using it since that basically forwards every port to that one IP.
 
okay so i am not too sure about the DMZ thing but the little i know points to the fact that it makes it vulnerable. Howvever, reagrding port forwarding there is a range of ports that i choose from at the setup page as in starting and ending port. Not sure what that happens, i am assuming that if i specify 100 - 200 so all those ports will be reserved for ftp ? . If anyone can provide me more info on DMZ it would be more helpful as in what exactly does it do .
