1. for forwarding you could
a. echo 1 > /proc/sys/net/ipv4/ip_forward (older distros have
ip_forwarding; pls check /proc)
b. use sysctl (available for new distro of linux)
this gets lost on reboot, so you have to put it in init like
network-scripts or rc.local ...
2. your arp is right.
what is arp -an? who is answering for who?
check your router's arp table (if you have one facing the linux box, it's
probably answering... :-)
the proxy arp and routing howtos are good references (and you get more
info). search google.
