You can either start up a routing daemon, e.g. "routed", on all of your
gateways, or you can set it all up explicitly as follows:
gw12:
route add -net <net1> netmask <mask1> dev eth0
route add -net <net2> netmask <mask2> dev eth1
gw23:
route add -net <net2> netmask <mask2> dev eth0
route add -net <net3> netmask <mask3> dev eth1
gw34:
route add -net <net3> netmask <mask3> dev eth0
route add -net <net4> netmask <mask4> dev eth1
Non-gateway on net1:
route add -net <net2> netmask <mask2> gw gw12
route add -net <net3> netmask <mask3> gw gw12
route add -net <net4> netmask <mask4> gw gw12
Non-gateway on net1net2:
route add -net <net1> netmask <mask1> gw gw12
route add -net <net3> netmask <mask3> gw gw23
route add -net <net4> netmask <mask4> gw gw23
Non-gateway on net1net3:
route add -net <net1> netmask <mask1> gw gw23
route add -net <net2> netmask <mask2> gw gw23
route add -net <net4> netmask <mask4> gw gw34
Non-gateway on net1net4:
route add -net <net1> netmask <mask1> gw gw34
route add -net <net2> netmask <mask2> gw gw34
route add -net <net3> netmask <mask3> gw gw34
