The Access Rights dialog configures the
access rights of the device. If no values are
entered here, any client can access the
device. As soon as at least one value is
entered only clients that fit into at least one of
the entries are allowed to access the device.
Each entry consists of an IP address and a
subnet mask: 192.168.0.0 / 255.255.255.0
enables all clients within the network
192.168.0.x. An entry 192.168.0.1 /
255.255.255.255 allows only one client to use
the IRTrans WiFi. The access rights are active
for all TCP and UDP functions. To avoid a
complete lock-out it is always possible to
access the web front end from within the local
network of the device – even if there is no
entry for that subnet. Furthermore the USB connection can be used to unlock the device.
Due to space and performance restrictions in an embedded device it is hardly
possible to achieve a complete protection against hostile attacks. Therefore the
IRTrans WiFi device should be protected from hostile environments (e.g. the
Internet) using a firewall.
The IR Relay configuration is used to configure
the relaying of IR signals from one IRTrans
LAN/WiFi to another. In general IR signals
received by other IRTrans LAN/WiFi modules
will be relayed automatically. This relaying
works without a server – even with IRTrans
devices without an integrated IR database. The
exact configuration of the relaying is done in
this dialog.
In the list below “Accept IR Relay from“ all
IRTrans IP Addresses can be entered from
which IR relaying should be enabled. If the list
is empty, all signals will be relayed.
The list below “Send IR Relay to“ tells the
system to which devices received IR codes
should be relayed. Normally it is enough to
enable the checkbox „Broadcast IR Relay“. Only if IR data should be relayed to routed
networks it is important to enter a target address because broadcasts will not be routed.
The IR receiving of the irserver is also done via that broadcasts. That means either
broadcast has to be enabled or the address of the host running the irserver has to be in this
list – otherwise the irserver will not receive IR codes from this IRTrans module.
The UDP Broadcast fields are only used for modules with integrated IR Database. They
define to which address and port formatted IR receive data has to be sent. The precise
