Public lan ip assigning for a internal network server

[midhunlaln66]

Hi all,

In our networking lab we purchased public lan ip from my provider (ISP)and they advertised lan ip in our network. Now i am planning to assign one public ip to a server which is available in my lab.I need to access this server from outside (publicly).How I can achieve this.

Airtel->asa firewall->asr router->core sw->lan.

This is the traffic flow in lab.what changes i need to do in firewall and router.plz support me.

Thanks in advance.

Hello

You will need to perfrom Network/Port AddressTranslation (NAT/PAT) either on the Firewall or RTR depending on which device you manage.

ASA example PAT https
object network LanHost
host 192.168.1.10
nat (inside,outside) static 1.1.1.1 service tcp 443 443
access-list 100 exteneded permit tcp any object LanHost eq 443

RTR example PAT https
ip nat inside source static tcp 192.168.1.10 443  1.1.1.1 443
