SNMP Trap
List box: Off, On
Default = Off
If “
On
”, SNMP alarm traps are activated. They are transmitted for Watched values according to the
settings in Alarm management (Settings/Device/Alarm management or Routing/Backup). The SNMP
Trap message is sent both when a parameter value exceeds the alarm threshold and when it returns
back within its “normal” range. The Trap OID is the same, the info whether it is alarm activation or
deactivation is in Trap data.
○
Trap destination 1
IP
address and
Port
where SNMP trap messages are sent. Default Port is 162, however it can
be changed. IP 0.0.0.0 means, that SNMP trap is not sent.
○
Trap destination 2
SNMP trap messages can be sent simultaneously to two different destinations.
Firewall
•
IP (L3)
List box: Off, On
Default = Off
If “
On
”, a standard Layer 3 Linux firewall is activated.
○
Port
– a range of port numbers can be entered. E.g. 2000-2120.
○
Connection state
– state-firewall active only for TCP protocol.
○
New
– rrelates to the first packet when a TCP connection starts (Request from TCP client to
TCP server for opening a new TCP connection). Used e.g. for allowing to open TCP only from
RipEX network to outside.
○
Established
– relates to an already existing TCP connection. Used e.g. for allowing to get replies
for TCP connections created from RipEX network to outside.
○
Related
– a connection related to the “Established” one. e.g. FTP typically uses 2 TCP connec-
tions – control and data - where data connection is created automatically using dynamic ports.
Note
1.
Port 443 and 8889 are used internally for service access. Exercise caution when
making rules which may affect datagrams to/from this port in L3 Firewall settings.
Connection between your PC and RipEX may be lost. When this happens, use
the Reset button on the bottom side of RipEX (keep it pressed for 15 sec.) in
order to set Default access, which restores the default Ethernet IP, default
password, sets the L3 Firewall to Off, sets ARP proxy&VLAN settings to Off and
Ethernet speed to Auto.
2.
L3 Firewall settings do not impact packets received and redirected from/to Radio
channel.
