If the Host modem has a static IP address, enter it in the Destination Address for S53. In Wireless
Ace, select Misc in the side menu.
FIGURE 9. Wireless Ace: Destination IP
Dynamic IPs
If you do not have static IPs, the remote modems need to be configured to report their current IPs to
a Dynamic DNS (DDNS) server with IP Manager (page 11). You will need to match the name of
the modem to the names specified in the host modem’s MLIST or MLISTX for the connected
RTU.
Instead of an IP, for S53, specify the name of the host modem (*MODEMNAME). If the remote
modems are using a different DDNS than the host modem, you will need to specify the fully quali-
fied domain name (*MODEMNAME+*DOMAIN).
With a name instead of IPs for the host modem, the remote modems will query the DNS server for
the current IP assigned to the host modem before sending data back to the host.
3. Configure IP addresses for the host.
Setting the Host modem IP address as the S53 Destination Address provides a low
level security. The modem will not forward UDP traffic unless the source IP/port
matches what is in S53.
However, if you set *AIP=1, the modem will forward UDP traffic from any source
IP address as long as it is accessing the modem on the configured *DPORT.
4. Configure other RTU settings.
