How to configure NAT

root@myhost:/etc/ipf# cat ipnat.conf 

map vmxnet3s0 192.168.2.0/24 -> 0/32 proxy port ftp ftp/tcp

map vmxnet3s0 192.168.2.0/24 -> 0/32 portmap tcp/udp auto

map vmxnet3s0 192.168.2.0/24 -> 0/32

if need rule for access to 22 port to zone IP we can add

rdr vmxnet3s0 0/0 port 2222 -> 192.168.2.2 port 22

if will add access to zone 192.168.2.2:22 from external IP:2222
