To test different network paths from ship to shore using each WAN option directly. For this test we used a fitlet2 computer with 4 Gigibit Ethernet ports.
fitlet2 J3455 Barebone 16 GB RAM for Fitlet2 512 GB SATA SSD for fitlet2 FC-M2LAN FACET-Card (2x Gbit Ethernet)
Edit /etc/network/interfaces and add a static IP for each WAN
auto eth0 iface eth0 inet static address [[KA]] netmask [[255.255.255.0]] network [[KA network IP]] broadcast [[KA Broadcast]]
Edit /etc/iproute2/rt_tables to create local tables
# # reserved values # 255 local 254 main 253 default 0 unspec # # local # Create multipath routing tables for Sealink and KA and Cell if available # A table can also be created to send traffic out the regular ship (via cyberoam and peplink) 1 sealink 2 ka 3 cell 4 ship
Create /root/bin/multipath.sh
The multipath script needs to be run as sudo, so have installed it in /root/bin
# multipath.sh # script to add routes out each WAN using tables created above ip route add default via [[ka static ip]] dev [[ka eth]] table ka ip route add default via [[sealink static ip]] dev [[sealink eth]] table hsn ip route add default via [[cell static ip]] dev [[cell eth]] table cell ip route add default via [[ship static ip]] dev [[ship eth]] table ship # Add rules to the rules ip rule add from [[ka static ip]] table ka ip rule add from [[sealink static ip]] table hsn ip rule add from [[cell static ip]] table cell ip rule add from [[ship static ip]] table ship ip rule list
