hi, I want to access the OPC-UA endpoint of Server 2 where the DB is installed from Server 1. But access is denied. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/8/582656512452ff5eba7b3552461cd5a4760d9659.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/b/5b7e3d1cc79fa9a368b7a334671362d8e4b5da44.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/9/d91a6fc81dfc16ab527ba78038c11d6e3db71b94.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/7/a736c49b44ffafd379452697637823ac1e1ffa6d.png) Portforwarding is complete. Thanks for reading. ---

After changing these settings on the server a restart is necessary. ---

Is there anything else to check? ---

Firewall on both servers maybe? Right now you have a networking error that means either the server isn't listening on the address/port specified or that a firewall is blocking the connection or something. ---

um.. > [@Kevin.Herron](#): > > Right now you have a networking error that means either the server isn't listening on the address/port specified or that a firewall is blocking the connection or something. The IP address in the picture above was tested with my server IP address. localhost works, but I can't directly enter my IP address. Is this also a firewall issue? ---

Maybe, but usually that means you didn't restart the Ignition Gateway after changing the settings. ---

To be clear - you are changing the server settings (first screenshot) on Server 2, have restarted Server 2, and now you're on Server 1 trying to make an OPC UA client connection _to_ Server 2? ---

Instead of using a list of addresses for the bind address, what if you just use the 192.168.0.7 IP or 0.0.0.0? You would have to restart again after making that change. ---

> [@avaughn](#): > > what if you just use the 192.168.0.7 IP or 0.0.0.0? ok. but I can't try it because it's not my office right now (I'm in Korea). I'll try it after I get back. Thank you for answer! ---

I can't try it because it's not my office right now (I'm in Korea). After coming back, I'll try reviewing the firewall and restarting the gateway again. Thank you for answer! ---

I think I actually am incorrect about not being able to pass a list to that configuration, but I was thinking maybe only the first address is successfully binding. Do you have the full logfile available that you could share? ---
