Hi Michael,

Very sorry for the late reply. Please find the mygw.conf and acf_rules, pv_names files in text format.

Thanks for your help.

Could you please attach mygw.conf as a text file?

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.

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.
