    I have a new linksys router, the Linksys WRT54GL,
    Since i have this router i am trying to do a port forwarding with the ports 25,80 and 110.
    I filled in all these ports at the forwarding page and forwarded them all to the correct pc running on my network.

    now when i try to connect with my homepage, it all seems to work (from within the network)

    But when somebody else, from outside the network, trys to connect with my ip and stuff, he does not get connected with my website.

    Sow the port forwarding does only work local.
    Can anybody tell me what i am doing wrong with this? is there a option that blocks request from outside my network??

    (with my previous router it all worked fine, but i needed wireless so i bought a new one and thought a linksys would be a good one, but it doesn't work)

    the internal port can be anything you like and outside port needs to be 80
    the default port...
    I don't know what you did before but thats the way it should be - I think.

    yes and that is the way i filled it in...

    and locally it is working as it should, but from the outside it is not able to connect.

    From the outside it is only possible to connect with the routers admin page. not with any other page (and it is running on port 8080, not 80)

    Those are all ports that most isp's block unless you pay for buisness service. Try moving your services to open ports and see if it works.

    Locally you do not need forwarding... only the PC name: \\LOCALPCNAME\ will automatically load port 80 default page on that machine. If you forward port 80 to that PC a remote pc (from outside on the internet) will behave the same as a local... "\\INTERNET IP\" or "\\www.url.com\" if you need a free URL you can use a service like DynDNS.com, etc.

    I just tested forwarding port 80 to my "serverpc" and I received the default page for my IIS test server... From outside without the port forward my browser gives an error... from local if I enter my url I get the router...

    Check with your ISP that they are not blocking these ports as lot of ISP's to stop users setting up mail/web servers block port 25/110 (mail) and 80/8080 (http). If they are doing this there is ways around it but it may cost a little money or effort i.e. DYNDNS.com do a kind of proxy service where the outside world connects to them (your DYNDNS url) on port 80 and they then forward it to you on what ever port you want or is not blocked. I also use a service from DYNDNS which does a similar thing for email, however the mail proxy costs me about $20-$30 per year but you do get a little value add as the email hit their mail servers, if your personal server is down your mail will be cached for around 10 days automatically.
