Many low-end ISPs with dynamic ip addresses block tcp port 80. You could always forward 8080 from the external ip to 80 on your rabbit so it would work without a code change. The router may allow you to forward it from port 80, but tcp port 80 is never making it to your router (from the isp).

I fixed the problem by defining HTTP_PORT 8080 and by making tcp_reserveport(8080) in

the code.

I'm not still not clear why it would not respond as regular port 80 as the router allowed me to uniquely forward all HTTP traffic to the RMC3700 IP address.

thanks

If your router is moving requests on its port 80 to the PC, it will not
reach the Rabbit unless you map router's port 80 to the rabbit and map
port 80 of your PC to other ports on the router

It is not clear from your message if port settings on the router was changed
to the rabbit's IP for port 80.

And also remember to set gateway IP address (to the router's) on the Rabbit.

I suggest that you run a sniffer (Ethereal, CommView etc) and look at the packets. AFAIK an http request string (GET) should be responded to by the Rabbit http server equally irrespective of its source.

Ken,

I have NAT setup in the router to forward all port 80 requests to the RCM3700.

I have narrowed the problem to the web server. Telnet'ing to the RCM3700 and

making the RCM3700 an FTP server work ok accessing it from the net.

If you don't have a static IP address (dial-up usually allocated a new one each time that you connect) you will have to reconfigure NATS and use the public IP that you have been given on each session.

I have done this in the past using a RCM2200 and others have been able to send HTTP gets to it from the Internet. I now have a static public IP and life is simpler.

Hi

Could anyone shed some light on this problem.

I have a RCM3700 programmed up as the simplest of webservers.

The RCM3700 and my local PC are connected to a switch and to the port of

a dial-up router. From my local lan PC I can ping the RCM3700 and surf to the web server with no problems.

When the dial - up router sees a packet not destined for the local lan it dials out and establishes a connection to the ISP and get served an IP address.

The router is setup to forward any incoming packets to the local lan with port forwarding.

This works fine for the PC. I have a web server on it and can surf to the PC from the net.

However the RCM3700 does not reply when attempting to surf to it from the net.

It seems that something in the RCM3700 causes it to ignore packets that come though the router yet the PC on that same local lan is ok.

I've attached several other devices on the local lan using port forwarding and been able to telnet and surf to those devices from the net, but cannot understand why the RCM3700 has problems.

any thoughts, suggestions.

Ronald

For you Rabbit to be "visible" from the Internet you must have Network Address Translation (NATS) enabled and set-up.
