Hi Lynn, This sounds like a firewall problem.  You said "firewall was closed".  What firewall are you referring to?  It could be either the Linux firewall or the Windows firewall.  To begin with I suggest completely disabling both firewalls.  If the firewall is the problem then re-enable them with rules to allow EPICS traffic to pass.

I try a lot, but i still failed.      I have 2 pc, first one was xspress Linux pc, which provided by the manufacturer;  the second was a windows pc.    The linux pc( xspress pc ): there are two NIC and one wireless, one NIC is 192.168.0.2 for device1 , another NIC is 192.168.2.31(for epics)    The windows pc: one wireless and one NIC:192.168.2.30( 255.255.255.0, gateway:192.168.2.1 and no gateway neither could worke )    192.168.2.30 and 192.168.2.31 was in same router, just has the two cables in the router.         Device connection was good, firewall was closed, IOC was good and started, pv name was right and i could caget from the linux pc itself.     I set both pc the environment to YES or NO/localhost or NO/192.168.2.31or NO/192.168.2.255. None could work.         I don't think it was a big question, but i do failed. After so many failed, maybe it's the question about network setting, so i put the setting bellow.   These thing has lagued me. Could someone give me some advice. epics> epicsPrtEnvParams EPICS_CA_ADDR_LIST: localhost EPICS_CA_CONN_TMO: 30.0 EPICS_CA_AUTO_ADDR_LIST: NO EPICS_CA_REPEATER_PORT: 5065 EPICS_CA_SERVER_PORT: 5064 EPICS_CA_MAX_ARRAY_BYTES: 6000000 EPICS_CA_MAX_SEARCH_PERIOD: 300.0 EPICS_CA_NAME_SERVERS is undefined EPICS_CAS_INTF_ADDR_LIST: localhost EPICS_CAS_IGNORE_ADDR_LIST is undefined EPICS_CAS_AUTO_BEACON_ADDR_LIST is undefined EPICS_CAS_BEACON_ADDR_LIST is undefined EPICS_CAS_SERVER_PORT is undefined EPICS_CA_BEACON_PERIOD: 15.0 EPICS_CAS_BEACON_PERIOD is undefined EPICS_CAS_BEACON_PORT is undefined EPICS_TIMEZONE: CST/CDT::360:030802:110102 EPICS_TS_NTP_INET is undefined EPICS_IOC_LOG_PORT: 7004 EPICS_IOC_LOG_INET is undefined EPICS_IOC_LOG_FILE_LIMIT: 1000000 EPICS_IOC_LOG_FILE_NAME is undefined EPICS_IOC_LOG_FILE_COMMAND is undefined EPICS_CMD_PROTO_PORT is undefined EPICS_AR_PORT: 7002 IOCSH_PS1: epics> IOCSH_HISTSIZE: 50 set: C:\Users\dell>set CATOOLS=C:\Program Files (x86)\National Instruments\LabVIEW 2022\user.lib\caLab\lib EPICS_CA_AUTO_ADDR_LIST=YES EPICS_CA_MAX_ARRAY_BYTES=6000000 EPICS_HOST_ARCH=windows-x64 [xspress3@xspress3 network-scripts]$ ifconfig enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500         inet 192.168.2.31  netmask 255.255.255.0  broadcast 192.168.2.255         inet6 fe80::201:2eff:fea3:132d  prefixlen 64  scopeid 0x20<link>         ether 00:01:2e:a3:13:2d  txqueuelen 1000  (Ethernet)         RX packets 1124  bytes 101271 (98.8 KiB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 2194  bytes 108450 (105.9 KiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500         inet 192.168.0.1  netmask 255.255.255.0  broadcast 192.168.0.255         ether 00:01:2e:a3:13:2e  txqueuelen 1000  (Ethernet)         RX packets 1253  bytes 159935 (156.1 KiB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 1244  bytes 434296 (424.1 KiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536         inet 127.0.0.1  netmask 255.0.0.0         inet6 ::1  prefixlen 128  scopeid 0x10<host>         loop  txqueuelen 1000  (Local Loopback)         RX packets 30655  bytes 2448058 (2.3 MiB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 30655  bytes 2448058 (2.3 MiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 virbr0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500         inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255         ether 52:54:00:36:41:17  txqueuelen 1000  (Ethernet)         RX packets 0  bytes 0 (0.0 B)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 0  bytes 0 (0.0 B)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 wlo1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500         inet 192.168.10.21  netmask 255.255.255.0  broadcast 192.168.10.255         inet6 fe80::83c1:3539:d0ad:203f  prefixlen 64  scopeid 0x20<link>         ether 68:54:5a:8a:07:e6  txqueuelen 1000  (Ethernet)         RX packets 91427  bytes 11020700 (10.5 MiB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 123470  bytes 50140843 (47.8 MiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 C:\user\Dell> ipconfig  Ethernet 2: 192.168.2.30 255.255.255.0 192.168.2.1 WLAN: 192.168.10.11 255.255.255.0 192.168.10.1 and type: casr 1 Channel Access Server V4.13 No clients connected.
