i have a openwrt installed router
like tplink 3420 v5
now fastd install installed server & router both side.
my server in USA and my router is france
server have 8IPS like 23.23.23.2 - 23.23.23.7
but server useing only 1IP 23.23.23.2 rest of 7IPS free like 23.23.23.3-23.23.23.7
now my france router have connected my linux PC
so i want to issue a static IP 23.23.23.3 to my linux server.
and my linux server have to be get this IP 23.23.23.3 from server.
now any one from the world get access on this IP:23.23.23.3
cause its an public IP .

when my linux pc get public IP then i can run any service as i want like SIP=5060 web=80,443 mysql=3306 etc like that.
i dont want any port FWD service.
i want my local linux pc have to get full real IP from my server.
so when my linux pc offline i can see ping down when online it will comes up ping up.
if you can make it let me know.
if you want to use any other vpn tunnel you can suggest me but not openvpn.
