Problems you may have include:

• The image screen remains gray.
• I get the error "load class ECTV not found".
• I get a "broken image" link.

You may be behind a firewall or a router that blocks or filters inbound traffic. You may be using a connection sharing device or connection sharing software. Or you may have Internet Security or Firewall Software installed. Any firewall software or hardware must be configured to allow access inbound to your PC on port 4020 TCP. Routers and/or connection sharing software must be configured to forward traffic on port 4020 to the "internal" or "private" IP of the PC running Broadcaster. If you are on a business or institutional Local Area network behind a firewall, you will not be able to broadcast unless your systems administrator makes specific configurations to allow this kind of traffic to your PC.

Devices and software known to restrict Broadcasting…

• Routers with NAT (Network Address Translation)
• Firewalls
• Firewall software (Black Ice, Zone Alarm, etc…)
• Connection sharing software (Win98 ICS, WinMe/2000/XP connection sharing, Wingate, etc…)
• Connection sharing routers (Linksys, Netgear, WebRamp, Belkin, DLink, DSL/Cable routers, etc…)
• ISP based or local Proxy server

Most of these conditions can be overcome by additional programming, contact your vendor or system administrator about opening and forwarding ports.

Additional notes:

Some ISP's use a proxy server between your PC and the Internet. In these cases, you may be able to circumvent this by using the "Use Local IP" setting in Broadcaster under "Access Control". Select this by checking it off and then restarting your broadcast. Some examples of ISP's that commonly do this are NTL and Freeserve in the UK. IMPORTANT: this WILL NOT resolve the issues stated in the first section above, it will only work if in fact the IP on your PC is a VALID internet IP and is not a "private" IP such as 192.168.x.x or 10.1.x.x (you can see your local IP in Broadcaster under "Local IP" in the "Access Control"). In these cases, you will need to configure your router, firewall or proxy to allow traffic from the net. Using the "Use Local IP" setting at this point would only have the affect of you being able to view your broadcast from within your local network range, users on the Internet would not see your broadcast.
