    Is this the right forum for this question?

    Probably not the right forum. But the issue here is that the ADSL router is probably not allowing UDP packets on port 42 to pass both ways.

    sorry about this confussion. I was trying to hosing my own webpage using the static ip by using the domain name that i had purchased, since my webserver is behind router so it can not be viewed by outside. I contacted the domain name company and they said that they need domain name server name. I think may be I have to set up my own domain name server before get my webpage up.

    53 is port for dns. I have forward all incoming traffic from the modem from port 1...65345 to the lan server when i try the url as it can be viewed but not for the domain name. How do i check whether the traffic is ok on port 53 in linux. at least i know port 80 is ok.

    What kind of router are you using?
    Checkout for nice freeware programs. Including a program for monitoring your webserver.
