How to forward requests from a host machine to a KVM guest and back using iptables
# echo 1 > /proc/sys/net/ipv4/ip_forward first
# 208.x.x.x is the host machine. 192.x.x.x is the guest machine
# This routes port 80 to the guest and back.
iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.x.x.x6:80
iptables -t nat -A POSTROUTING -p tcp -d 192.x.x.x6 --dport 80 -j SNAT --to-source 208.x.x.x
# This routes port 2222 on the host to 22 on the guest machine
iptables -t nat -A PREROUTING -p tcp --dport 2222 -j DNAT --to-destination 192.x.x.x6:22
iptables -t nat -A POSTROUTING -p tcp -d 192.x.x.x6 --dport 22 -j SNAT --to-source 208.x.x.x
