Configure iptables for NAT translation so that packets can be correctly routed through the Ubuntu gateway https://help.ubuntu.com/community/Internet/ConnectionSharing sudo iptables -A FORWARD -o eth2 -i eth1 -s 192.168.32.0/24 -m conntrack --ctstate NEW -j ACCEPT sudo iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT sudo iptables -t nat -F POSTROUTING sudo iptables -t nat -A POSTROUTING -o eth2 -j MASQUERADE
This might work better. ( This one works with Desktop Ubuntu ) iptables -t nat -A POSTROUTING -o eth2 -j MASQUERADE iptables -A FORWARD -i net0 -o eth2 -j ACCEPT iptables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
This may work better on Centos [root@is411 ~]# iptables --table nat --append POSTROUTING -o em1 -j MASQUERADE [root@is411 ~]# iptables --append FORWARD -i p2p1 -j ACCEPT
Work Fedora 20: iptables --table nat --append POSTROUTING -o em1 -j MASQUERADE iptables --append FORWARD -i enp0s26u1u2 -j ACCEPT
Configure access for natted virtual machine iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 5903 -j DNAT --to-destination 10.0.3.197:5901
