Topic: accessing arduino through at&t uverse router (Read 458 times) previous topic - next topic


I have been trying to access my arduino outside of my local network for a while now. I think i've set port forwards that direct to my arduino's ip address but i can't seem to get it working.

I can access it locally via I've set up port 85 to forward to the arduino's ip at port 85. I know my router's external ip. It's 99.70.245.xxx. I tried to go to http://99.70.245.xxx:85 on my phone(outside my local network) but i can't connect.

Here are a couple pics of me setting up the port forward. 



here is my arduino code. I tried manually setting the gateway and subnet, but that didn't work either. Anybody have any suggestions?

Code: [Select]

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1, 10);

//byte gateway[] = { 99, 40, 214, 1 }; //Manual setup only
// byte subnet[] = { 255, 255, 252, 0 }; //Manual setup only
// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(85);

void setup() {
// Open serial communications and wait for port to open:
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only

  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);
  Serial.print("server is at ");

void loop() {
  // listen for incoming clients
  EthernetClient client = server.available();
  if (client) {
    Serial.println("new client");
    // an http request ends with a blank line
    boolean currentLineIsBlank = true;
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        // if you've gotten to the end of the line (received a newline
        // character) and the line is blank, the http request has ended,
        // so you can send a reply
        if (c == '\n' && currentLineIsBlank) {
          // send a standard http response header
          client.println("HTTP/1.1 200 OK");
          client.println("Content-Type: text/html");
          client.println("Connnection: close");
          client.println("<!DOCTYPE HTML>");
                    // add a meta refresh tag, so the browser pulls again every 5 seconds:
       //   client.println("<meta http-equiv=\"refresh\" content=\"5\">");
          // output the value of each analog input pin
          for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
            int sensorReading = analogRead(analogChannel);
            client.print("analog input ");
            client.print(" is ");
            client.println("<br />");       
        if (c == '\n') {
          // you're starting a new line
          currentLineIsBlank = true;
        else if (c != '\r') {
          // you've gotten a character on the current line
          currentLineIsBlank = false;
    // give the web browser time to receive the data
    // close the connection:
    Serial.println("client disonnected");
