Hi @murph2390
You need NAT:
See this example.
ip nat outside source static 172.16.89.32 171.68.16
interface Ethernet1
ip address 171.68.192.202 255.255.255.0
ip nat inside
interface Serial1
ip address 172.16.191.253 255.255.255.252
ip nat outside
-If I helped you somehow, please, rate it as useful.-
