That should have worked.
Are you sure that you have set the subnet mask on your IOC machine correctly?

Hey,
thanks for the answers.
Unfortunately I did not work:
Here is what I tried:
~ > ifconfig p3p1
p3p1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::213:3bff:fe0f:e7bf prefixlen 64 scopeid 0x20<link>
ether 00:13:3b:0f:e7:bf txqueuelen 1000 (Ethernet)
RX packets 39249 bytes 5375914 (5.1 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 192403 bytes 81244106 (77.4 MiB)

Channel connect timed out: 'PANDA:LMD:MUPIX:HV:TLSCP:0:Vmom' not found.

PANDA:LMD:MUPIX:HV:TLSCP:0:Vmom 0.0489747
p3p1 is the name of the network interface to which all our EPICS IOCs
are connected...
