[Tweet](https://twitter.com/share) ### Hear from Pat Smith—guest blogger from OptoPartner Avadine—as he unveils an Ignition module designed to help you remotely configure and integrate *groov* products with Inductive Automation's Ignition platform. Why is this new module a big deal, and what does it mean for you? This advanced Ignition module gives you the ability to remotely configure and integrate with Opto 22 *groov* products directly from Ignition—from Port Redirect configuration and VPN control to the full suite of *groov* Manage APIs. What's more? Avadine is offering this module for *free* on the Ignition Exchange! Read on as Pat Smith from [Avadine](https://www.opto22.com/community/opto-partners/avadine) explains what led them to create this module and the problems it solves for you. ## **Why?** We wanted to configure temporary Port Redirect rules from Ignition to remotely allow developers to access unsecured PLCs protected by Opto 22’s [*groov* EPIC](https://www.opto22.com/products/groov-epic-system). While we were at it, why not expose ALL of the Opto 22 *groov* APIs as system functions in Ignition, so that numerous *groov* devices can be managed and orchestrated centrally from Ignition? ## **Wait. What are you talking about?** One of the best ways to secure legacy PLCs, controllers, and other devices is to obscure the device from the network and block all incoming traffic. With Opto 22's *groov* products, you can do just that! By physically putting an Opto 22 *groov* EPIC (or*[groov](https://www.opto22.com/products/groov-epic-system)*[RIO](https://www.opto22.com/products/groov-epic-system), in the near future) in front of legacy unprotected devices, they can be protected from bad actors.  With *groov* EPIC's dual NIC design and built-in firewall, you can connect the legacy PLC to EPIC’s **eth0** (the default LAN/**trusted** network configuration).  Then, connect to a public untrusted network (IT LAN, internet, etc.) with EPIC's **eth1** (LAN/**untrusted** network configuration).  The result is that the legacy PLC is obscured from the outside world, because eth0 and eth1 are physically separated and firewalled. But how do trusted/SCADA systems connect to the legacy device if the EPIC’s network segmentation and firewall block it? I'm glad you asked! ## **Port Redirect** Port redirection, also known as port forwarding, allows remote computers or mobile devices on one network segment to connect to a specific computer or service within a private LAN through a specific port. Usually, it pokes a “pinhole” in your firewall through which packets of information can pass. This port forwarding technique is unsecure and not recommended, especially when the remote computer is on a public LAN like the Internet. However, using port redirects over a VPN is secure and provides a conduit between the two network segments that can be very useful. For example, if you anticipate having to update a PLC’s program on a private network from your PC at a remote site, you can place a *groov* EPIC on the PLC’s trusted network and use the EPIC’s built-in VPN interface to port redirect over a configured conduit, securely accessing your PLC to make the change. ![portredirect](https://blog.opto22.com/hs-fs/hubfs/portredirect.png?width=700&height=498&name=portredirect.png) ## **That sounds awesome! But what does it have to do with Ignition?** You can configure Port Redirect rules directly in EPIC’s *groov* Manage under Network settings. The rules configured in *groov* Manage are persistent, allowing specific traffic over specific ports to traverse the internal firewall between two network interfaces on the EPIC until changed or deleted. ![AvadineBlog2](https://blog.opto22.com/hs-fs/hubfs/AvadineBlog2.png?width=306&height=250&name=AvadineBlog2.png) ![AvadineBlo3](https://blog.opto22.com/hs-fs/hubfs/AvadineBlo3.png?width=290&height=250&name=AvadineBlo3.png) But what if you want to dynamically add new Port Redirect rules from a central location, like some kind of application that can monitor and control devices? Something like IGNITION!?!  And what if the Port Redirect rules issued from Ignition could be configured with an interval so they would automatically turn off after the time expired? And what if you could monitor and orchestrate configuration changes to all of your Opto 22 *groov* devices centrally from Ignition? With the Opto 22 Integration module, now you can! Use Case: A legacy/unsecurable PLC is protected by a *groov* EPIC and, therefore, cannot be remotely connected from engineering workstations for development or logic changes. A SCADA admin logs into the Ignition Perspective application and temporarily creates a Port Redirect rule for an engineering laptop's IP address to connect to the legacy PLC over a specific Allen-Bradley TCP Port. The rule is configured to stay open for only one hour. After one hour expires, the rule is disabled, and the engineer is no longer able to access the legacy PLC.
