Make sure in your Linux system was installed and configured DHCP Server. This is example testbed configuration:
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp-server/dhcpd.conf.example
# see dhcpd.conf(5) man page
#
option domain-name "c.jkt-probes.xtremenitro.org";
# specify DNS server's hostname or IP address
option domain-name-servers 8.8.8.8,8.8.4.4;
# default lease time
default-lease-time 600;
# max lease time
max-lease-time 7200;
# this DHCP server to be declared valid
authoritative;
# specify network address and subnet mask
subnet 192.168.255.0 netmask 255.255.255.248 {
range 192.168.255.2 192.168.255.6;
option broadcast-address 192.168.255.7;
option routers 192.168.255.1;
interface eth0;
}
$ sudo dnf install ModemManager NetworkManager -y
$ git clone ~dewanggaalam/gsm-ripe.git
$ cd gsm-ripe
$ chmod +x gsm-ripe/gsm-ripe.sh
$ sh gsm-ripe.sh
Raspberry Pi 3 setup as router, make sure you change net.ipv4.ip_forward to 1. And create masquerade to all interface that physically connected.
$ sudo ip route show table all | grep "table" | grep -v "local"
default via 10.229.241.1 dev wwan0 table INDOSATOOREDOO
default via 10.211.132.202 dev wwan1 table XL
$ sudo ip rule ls table INDOSATOOREDOO && ip nei sh | grep 192.168.255.4
32764: from 192.168.255.4 lookup INDOSATOOREDOO
192.168.255.4 dev eth0 lladdr 18:d6:c7:2a:05:a2 STALE
$ sudo ip rule ls table XL && ip nei sh | grep 192.168.255.5
32765: from 192.168.255.5 lookup XL
192.168.255.5 dev eth0 lladdr 14:cc:20:48:ca:f0 REACHABLE
We can saw, the output is mapping from each probes to each WAN/GSM Provider using route table.
