Typical Router Settings
These are setting required when first setting up a router to work on Exeltel Broadband:
VPI: 0
VCI: 38
Encapsulation/Protocol: PPPoATM or PPPoE (RFC2364)
Framing Mode: VC-MUX / Null
WAN IP & Gateway configuration: Negotiate upon connection
Note that it is important for the gateway IP to be automatically negotiated as we will use a range of different gateways determined upon connection.
Modulation Setting
Modern routers will offer an automatic setting for modulation which will detect the type of service provided.
DNS Settings
DNS should be configured to be negotiated upon connection, however, where these are required to be manually configured they are as follows:
Primary: 88.215.61.255
Secondary: 88.215.63.255
Routed IP Configurations
Routed IP ranges are provided in groups of 4 or 8 IP’s. The number after the slash denotes how many IP’s there are in the range in CIDR format.
/29 = 8 IPs (6 usable) – Subnet: 255.255.255.248
/30 = 4 IPs (2 usable) – Subnet: 255.255.255.252
The first IP in the range is reserved for broadcast and the last is the network, these are not usable IP’s.
One of the usable IP’s must be allocated to the LAN interface of the router with the appropriate subnet listed above. For all other devices within the LAN, they will need to be allocated the remaining usable IP’s and have the LAN IP of the router set as the gateway.
Please note that for routed IP configurations, Network Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP) must be disabled for the routing to work correctly.
