Hello,
What version are you running, lets say its 8.3 or a higher version.
In order to access the host by its public ip address from hosts behind the same interface you need the following :
object network 172.19.4.41
host 172.19.4.41
object net 65.82.180.195 ( outside ip address)
host 65.82.180.195
object service http
service tcp source eq destination 80
nat (laN,laN) 1 source dynamic any interface destination static 65.82.180.195 172.19.4.41 service http http
Give it a try and let me know.
