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
