No usage.
iptables is not required for routing.
2) Must there be two (or more) NICs in order that there will be
any usage for setting /proc/sys/net/ipv4/ip_forward?
yes to experience usage of that you must have 2 NICs whose IP set to
2 different IP networks.
This is incorrect, you can do several different kinds of routing
using a single NIC (ie with subinterfaces or ipmasq rules). Google
"router-on-a-stick" for examples..
