126.96.36.199. IP Security Feature
The IP Security feature can be used to restrict unauthorized IP addresses from
establishing a connection with the RPC. In the default state, the RPC accepts
incoming IP connections from all hosts. To conﬁgure the IP Security feature,
proceed as follows:
1. Access the IP Security Menu:
a) Web Browser Interface: The IP Security feature is conﬁgured
using the ﬁelds at the bottom of the Network Parameters Menu as
shown in Figure 5.9.
b) Text Interface: Go to the Network Parameters menu (/N), type 5
and press [Enter]. The IP Security menu will be displayed as shown
in Figure 5.11.
2. The IP Security menu lists ﬁve IP Security "masks" along with the
selected permit/deny action for each mask.
a) Each Security Mask prompt deﬁnes a speciﬁc IP address or range of
addresses. Each Mask Action prompt deﬁnes the permit/deny action
for the corresponding mask.
b) Masks are listed in order of ascending priority; Mask 1 has the
lowest priority, Mask 5 has the highest priority.
c) Masks have a cumulative effect; high priority masks supersede the
effect of lower priority masks.
d) Each IP Address consists of a series of four eight bit numbers. The
number 255 is used as a wild card.
