4.1 Several Teldat-3Ge in the same corporate LAN

Particular care must be paid when installing several Teldat-3Ge devices on the same LAN network, especially when
it comes to configuring the DHCP protocol. The DHCP server must identify the Teldat-3Ge s and offer different IP
addresses to each. The Teldat-3Ge s are identified through the MAC address assigned to the device's Ethernet in-
terface. The MAC address value is found on the label attached to the underside of the case containing the device.

4.1.1 Two Teldat-3Ge devices serving a router

DHCP server configuration in a Teldat router where two Teldat-3Ge devices serve a single router:
protocol dhcp
; -- DHCP Configuration --
server
; -- DHCP Server Configuration --
subnet subnetea 0 network 172.24.0.0 255.255.0.0
subnet subnetea 0 bootfile fwethant.img
subnet subnetea 0 next-server 172.24.78.29
subnet subnetea 0 router 172.24.78.29

;
host eth-ant1 0 ethernet 00-a0-26-53-29-02
host eth-ant1 0 fixed-ip 172.24.78.31
host eth-ant1 0 option 43 asc antenna&sipport=5060&localphone=607081119
;
host eth-ant2 0 ethernet 00-a0-26-53-29-03
host eth-ant2 0 fixed-ip 172.24.78.32
host eth-ant2 0 option 43 asc antenna
In both configurations, the device with physical MAC address 00-a0-26-53-29-02 is given the SIP configuration and is
the equipment that acts as the SIP-gateway. The other device will only back up data.
Moreover, when compared to the basic scenario explained in this document, in this case the user needs to specify 2
PPP interfaces (each one with an rcellular base interface and each of these with their L2TP tunnel). Consequently,
and as you can see in the resulting configuration that follows, 6 rcellular interfaces and 6 L2TP tunnels are con-
figured in the router.
