| + | ==== Enable IP Forwarding First ==== | ||
| + | <code> | ||
| + | sed -i 's/.*net\.ipv4\.ip_forward.*/net.ipv4.ip_forward = 1/' /etc/sysctl.conf | ||
| + | sysctl -p | ||
| + | </code> | ||
| + | |||
| + | ==== NAT using iptables ==== | ||
| + | |||
| + | === Recommended Way (If IP is static) === | ||
| + | <code> | ||
| + | iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -j SNAT --to-source <IP> | ||
| + | </code> | ||
| + | |||
| + | === Another Way (OpenVZ won't work this way) === | ||
| + | <code> | ||
| + | iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -j MASQUERADE | ||
| + | </code> | ||
| + | |||
| + | Or if you want to MASQUERADE all interfaces: | ||
| + | <code> | ||
| + | iptables -t nat -A POSTROUTING ! -o lo -j MASQUERADE | ||
| + | </code> | ||
