However, entering localhost limits access to the RFM220 Aggregator to only the RFM220 Clients that are installed on that PC or server. It is recommended that you use the IP address instead of localhost since that will allow RFM220 Clients to access the RFM220 Aggregator from PCs other than the one hosting the Aggregator.
Page 51 NOTE. The RFM220 Aggregator supports two trap destinations. The ﬁrst destination is always set by the RFM220 Aggregator to itself so that it can record all alarms.
