I am a bit new to OPC, and so I am trying to test some connections and see how they run. Inside an internal network (home based lan), I have the Ignition OPC server running on a desktop. The IP address for the desktop is 192.168.254.115. I have started a project using the simulated PLC driver. By the way, I have installed this on a linux desktop, running openSUSE 12.3. The networking issues should be basically the same, I think, as any other platform. When I open the gateway and go to Configure -\> OPC-UA -\> Certificates, under “This Gateway”, it has my ip address listed as: ```auto IP Address 192.168.1.101 ``` At one time, I think before I installed ignition, I did have the local network with the ip addresses using 192.168.1.xxx instead of 192.168.254.xxx. My ifconfig status shows: `eth0 Link encap:Ethernet HWaddr 48:5B:39:38:8A:57 inet addr:192.168.254.115 Bcast:192.168.254.255 Mask:255.255.255.0 inet6 addr: fe80::4a5b:39ff:fe38:8a57/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:138343 errors:0 dropped:0 overruns:0 frame:0 TX packets:193719 errors:0 dropped:0 overruns:0 carrier:5 collisions:0 txqueuelen:1000 RX bytes:48261869 (46.0 Mb) TX bytes:81755684 (77.9 Mb) ` My goal is to be able to connect to the gateway from a remote pc on the same lan. My laptop, which connects by wireless, has an ip address of 192.168.254.118. Is it possible to connect to the gateway by the lan? I have been assuming that I should do this before I try and connect a client remotely through the lan. Do I need to force the OPC-UA server to be set up on the correct ip address? I don’t know why it picked up the old addressing scheme. Thanks for your help in advance. ---

Neramdaman: Under opc-ua - settings , check what the IP is set too. Also check to see what your /etc/hosts file contains. It may still have an old 192.168.1.101 entry. -Mike ---

Thank you. Refreshing my ip address and then regenerating the certificates did the trick!
