Re: PVA Gateway issues with two networks client

Hi all,

I forgot to add the mygw.conf file contents in the earlier email. Please find the my gateway configuration details below.

Any help is welcome.

Thanks,

Sai.

Hi all,

I am facing while running the PVA gateway and configuring two networks. The scenario is that I have class C 192.x.x.x network and 10.0.1.x network configured on the PVA gateway. I am running the IOC (exampleCPP) on 10.0.1.10 (VM) and I am able to access the PV's (PVRint, PVRlong, PVRshort, PVRbyte) from 192.168.0.106 (Windows) machine. Everything works fine.

Now, I have added a new Windows machine with two NIC cards, Ethernet with 192.168.0.107 and a USB to LAN cable with 10.0.1.33 configured. With this machine, I am able to access only the PV's using 10.0.1.x network (without the PVA gateway running). With the PVA gateway running, I am unable to access the PV's in Phoebus using 192.168.0.107 IP address. I tried to check the ACF rules file, PV list file but to no avail. 

Please find here the ACF rules file and PV list file contents attached here for reference.

Any help or suggestions why the PV's access using the PVA gateway with the 192.x.x.x network is not working would be appreciated.

I am suspecting that the PVA gateway is binding the MAC address of the machine with a particular IP address. Can somebody confirm if this is the case? 

Also, is there a way to check the PVA gateway logs as to get a peek at what's happening within the gateway?

Thanks,

Sai
