Thanks for your help, Hoba
if i have 3 real IPs : 212.172.11.27, 213.172.11.27, 214.172.11.28.
Although i have read the tutorial many time but seem i not be able to understand well so that you can base on 3 ip real ips and give me some major setting on pfsense.
To ngoc ( may be you are VietNamese) ::)
Can you give me your email i want some questions about the pfsense want to ask you. Thanks Ngoc so much
