On the machine that is configured for 1.2.3.5 ifconfig eth0:0 192.168.1.1 netmask 255.255.255.0 echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -j MASQUERADE
On the machine that is configured for 192.168.1.2, make its default gateway 192.168.1.1 SNAT is for Statically NATting the source address. DNAT is for Statically NATting the destination address. You may overload an ip address, but it acts as loadbalancing, not sharing. Masquerading acts more like PAT (port address translation). The MASQERADE-ing machine handles the address sharing.
