About the ports
In router models C1111 and C1131, LAN port
0/1/0 is reserved for 5G outdoor unit. No
other LAN devices may be connected to it.
5G outdoor unit is not available with C1117-
4PMLTEW router.
In router models C1111 and C1131, LAN port
0/1/1 is reserved for connecting an external
WLAN additional base station that can be
ordered as an additional service, and local
network devices may not be connected to
this port. Additional WLAN base station is not
available with C1117-4PMLTEW router.
Ports 0/1/2–0/1/3 on the router power
PoE-compliant devices. If necessary, you can
connect other PoE-compliant LAN devices
to these ports. The ports are also compatible
with data-only connections. PoE is not
available with C1117-4PMLTEW router.
Ports 0/1/4–0/1/7 are traditional RJ45
10/100/1000 Ethernet ports, with router
C1117-4PMLTEW corresponding ports
0/1/0–0/1/3, and can be used to connect LAN
devices to the service.
Port 0/1/0 is reserved for connecting the
5G outdoor unit. No LAN devices must
be connected to it.
Port 0/1/1 is reserved for an external
wireless access point (supplementary
service). Do not connect any local area
network device to this port.
The RJ45 10/100/1000 Ethernet ports
0/1/2–0/1/3 are intended for connecting
LAN devices. The ports have PoE power
supply capability.
The RJ45 10/100/1000 Ethernet ports
0/1/4–0/1/7 are intended for connecting
LAN devices. The ports do not have PoE
power supply capability.
The port is not used. Cannot be used for
connecting LAN devices.

Default network
and firewall
By default, the private network
192.168.200.0/24 is configured
for LAN ports 0/1/x and the wireless local-
area network provided as a supplementa-ry
service. This can be changed with the
supplementary service Räätälöity DHCP
(Custom DHCP).
By default, the network is configured as
follows:
Default route: 192.168.200.254
Subnet mask: 255.255.255.0
Static addresses available to the customer:
192.168.200.193–192.168.200.253
Addresses assigned by DHCP: 192.168.200.1–
192.168.200.192 (192 addresses)
DNS servers: 193.210.19.19, 193.210.19.190
The router performs a network address
translation (NAT/PAT) for private IP address-
es used by customer devices. Traffic from the
default network is protected by a standard
stateful firewall rule set that cannot be
changed. All traffic from the Internet to the
customer’s local area network is blocked by
default, but all traffic originating from the
customer’s network is allowed, including
returning packets. The default network,
address translation and firewall are enabled
when no supplementary Avoin Internet
(Open Internet) service is connected to the
subscription.
The purpose of the ports is illustrated
in the figure below.
