Jason, So I would do something like [0:0] -A PREROUTING -d 66.121.12.64/26 -j NETMAP --to 10.0.12.64/26 Instead of: [0:0] -A PREROUTING -d 66.121.12.64 -j DNAT --to-destination 10.0.12.64 And [0:0] -A POSTROUTING -d 10.0.12.64/26 -j NETMAP --to 66.121.12.64/26 Instead of: [0:0] -A POSTROUTING -o eth0 -s 10.0.12.64 -j SNAT --to-source 66.121.12.64 And [0:0] -A OUTPUT -d 66.121.12.64/26 -j NETMAP --to OUTPUT 10.0.12.64/26 Instead of: [0:0] -A OUTPUT -d 66.121.12.64 -j DNAT --to-destination 10.0.12.64 Is this correct?
