HTTP Port Forwarding

Randy Ayscue

• April 17, 2019 17:56

We have several sites that we access through a cellular modem. Each site has a PLC, HMI, VPN router, and of course the modem. We have been using a Cisco VPN router but wanted to try a Cosy 131 because we have been having issues with the Cisco. I have been able to configure the Cosy to do everything we need thus far with one exception, I need to be able to access the HMI using the public IP address without going through Talk2m. The Cisco allows us to set up port forwarding from the public static IP address to the IP address of the HMI on the LAN. I have already changed the settings in the Cosy that allows WAN to LAN but how do achieve the HTTP forwarding?

  Kyle,

  Can you point me to where these settings are in the Cosy configuration?

  Those network settings can be changed if you run the Internet Wizard, top right hand corner of screen.

  Kyle,

  Changing to static WAN seems to have fixed the issue with connecting to the internet without having to power cycle the Cosy. Everything seems to be working properly now. So I have just installed another Cosy in a different system and I can't connect to the HMI or get alarm emails from the HMI. I have attached a backup file. Will you check it and see if there are any issues? Just to let you know, I thought I would save time by restoring the backup for the working Cosy to the new one and then go in and change the IP addresses. Was that a bad idea?

  Hi Randy,

  It's not a bad idea to restore from a backup, but you need to make the device backup before connecting to Talk2M because the devices need to have unique identities in the config files or it will cause connection problems.

  Looking at your settings though, I can see you need to change WANItfProt from "1' to "2' so try that and see if that does it.

  Kyle,

  So I'm trying to get everything working for this Cosy installation. This is my second location replacing a Cisco router with a Cosy. The first location where I installed the Cosy is still working fine. For the second location I can connect to the HMI web interface and I can connect to the Micrologix PLC. The issue I am still having is that I am not getting emails from the Red Lion HMI. Originally we thought it was related to the NATltf setting. I have tried setting it at 2 and 3 but neither seems to make a difference. Both Cosy locations have identical hardware and the same settings as best as I can tell. I have attached a backup. Can you check and see if you seen any errors or anything that might prevent the forwarding of emails?

  Thanks,

  Randy

  Hey Randy,

  I took a look at the logs and configs and you need to make these changes:

  1. Check network settings on HMI and make sure that the default gateway is set to be the Cosy's LAN address (10.0.37.254)
  2. Change "FwrdToWAN' from 0 to 1
  3. Change "NATItr' from 3 to 2.

  Then reboot and give it another shot.

  Thanks!

  Kyle,

  Thanks for the info. All seems to be working now. It seems my idea of restoring a backup from the other Cosy did not work. I thought I could do this and then just change the IP addresses. However it seems some of the settings did not carry over. I suppose I just need to make a list of the proper settings and then just enter them each time.

  You wouldn't want to restore a backup from a device which had already run the VPN/Talk2m Wizard, because each device has unique keys, but you could change the settings you wanted before running the Wizard and then back up. You can also add your tags or settings to the config files (txt files) using FTP.

  Thought I would give replying to this thread a shot even though it has been closed. We had resolved my issue some time ago but it has come up again after we changed our email provider. After our SMTP server address changed I no longer receive emails from the device that is connected to the Cosy. We are supposed to have a conference with our internet provider this afternoon to see why the emails are being blocked if indeed that is the issue. I wanted to send the backup file from the Cosy to see if you see anything that might help to resolve the issue.

  Thanks,
  Randy
