    I've been trying to solve this problem for over 4 months now by myself so any help would be appreciated. I don't like asking without trying to solve and search for this by myself first, but I just can't do it

    Setup:
    - Desktop Computer (works fine when directly connected)
    - Laptop Computer (works fine when directly connected)
    - Cable Modem
    - Wireless-G Router (Model CWR-854) - Firewall enabled - All wired connections - No wireless enabled

    Problems:
    1) BitTorrent won't work properly. “Checking for firewall...” just keeps going
    2) It won't allow access to internet banking sites completely. Accesses main pages, but times out when trying to log in.
    3) Google Videos and YouTube slower.

    Notes:
    When I disable the firewall on the the Wireless-G Router, everything works fine. It's just the settings on my router firewall which is messing things up.

    Attempted Solutions:

    For 1) Allowed port 6881 for inbound and outbound TCP access on router firewall - didn't work - tried disabling Automatic port mapping (UPnP) - didn't work

    For 2) Allowed port 443 (SSL) for outbound TCP - still didn't work

    For 3) Haven't tried anything!

    try setting up a static ip for the desktop then open port forwarding for those ports to the ip address of your desktop see if that takes care of your problem

    I'm no expert in this, but when the router firewall is up are there any other firewalls in use on the computers? We were having some problems similar to yours and when we lowered the computer firewalls and just use the router firewall everything works fine.

    This was how I solved problem 1):

    Don't use BitTorrent default client. Use uTorrent – from www.utorrent.com – Install. Open “the” port (check Utorrent -> preferences -> connections) in wireless router through Advanced -> Virtual Servers. Select IP address, the port (private same as public) and have it TCP forward to ....50 (default) It's Port Forwarding (www.portforward.com – see HTML webpage saved – utorrent.htm). Disable UpnP in uTorrent.

    :)

    Only 2 more problems to go!!

    Hi, I'm now working on the "Internet banking" Problem

    Here are the FACTS:

    1) Https:// when you need to log in to a site WORKS when directly connected to the 'net
    2) Https:// when you need to log in to a site DOES NOT WORK when thru the router
    3) Still doesn't work when I disable the firewall completely on router
    4) Can access https:// sites but not ones you need to log in to thru router
    5) In the router logs, TIMEOUT appears next to port 443 when trying to get into a log-in https:// website
    6) I have enabled port 443 outbound TCP in firewall - doesn't work even if I'm a lot more flexible in firewall

    My conclusions from the FACTS:

    The problem isn't in port configurations

    The problem is in a non-firewall router setting -> it is not allowing to establish and/or maintain a https:// connection which requires authentication via a username/password

    could be NAT - network address translation - not allowing the encryption through the link between the local IP address and the Gateway and then the Internet. It may be that the gateway is getting in the way........

    Any help?

    Alright crazy peeps.. I've solved the problem!!

    On my router I had an "intrusion detection" option which I had enabled. It is probably useful. However, it had blacklisted my HTTPS:// sites that I visit

    So once I disabled that, it was OK!

    But before coming to that conclusion, I tried switching off my software firewall as I thought that may have been getting in the way. Still didn't work. So concluded it was another router setting. So HMMF finally!!!!
