Note that in the JACE’s platform TCP/IP configuration, no DNS servers should be defined—otherwise, the GPRS modem will not function. The intended application for a GPRS modem is on a site where no DNS servers can be reached on the local Ethernet network, or where no local Ethernet network exists.

Also, it is recommended to not use DHCP on any Ethernet adapter when the GPRS modem option is used.

Figure 10 shows an example JACE’s platform TCP/IP configuration view, where no DNSv4 servers are defined, and DHCPv4 is not enabled.
