Hi in the company i work for i use a 3G router over a private vodafone network back to head office.....

there is a agent installed on my pc in the office that lets only my pc connect to the router and its devices on it.

i have 10 of these devices and i am using port forwarding on them for the tills that are connected and they work fine.......

my problem is when i connect a ip web cam to the box and set up the ip and port frowarding
i can not make connection to the webcam....

but if i put the web cam ip into the DMZ i can connect to it no problem... any hints of what going wrong

    Why are you using 65535?  I can't say "it won't work" because I've never tried it, but it's possible it may be out of range.

    Try using something simple like 8081 and see if that works.  Don't forget to put a :8081 on your webaddress in your browser...

    If it works and you don't like 8081, you can change it later after you know it's working...

    Hi ya i have tryed 80 9191 9292 100 78 65535
    i know it works as the till software i use uses 65535

    i had the camera set up on port 9292 with no look so i disconected the till form the routher
    and just had the ip camera connected with ip address of port 65535 and i get nothing. but as soon as i put it into the Dmz

    and open up internet explorer and put in the ip address forrlwed by :65535 it works but only when its in the dmz on the router

    Are you sure that you don't need more than one port?

    Do a telnet test from outside the router to verify if you are getting a connection on whatever port is redirected.

    telnet <ip address / host name> <port>

    If you get an error saying it can't connect that means the port forwarding isn't working or the device isn't listening on that port.  If however you get a connection (might just be a blank nothing), that means the forwarding is working, but you might need something else for it to work.
