ASA access rule relative to port forwarding

Dr.X
Level 2
Level 2

hi all ,

just simple question

assume i have    inside==ASA====outside========intnet

assume outside public ip is x.x.x.x

asusme i made a portforward on outside interface ,

assume my lan is 10.10.10.0/24

assume to reach my server 10.10.10.2 i need to go x.x.x.x:5050

the question is about the access rule that need to be allow the outside traffic that comes inside .

why i need to allow destination to ip 10.10.10.2 in the access rule ???

shouldnt we allow the access to x.x.x.x:5050 ip ???

question agian ,

why we need access rule that allow traffic that enter form outside to inside , and dont need rule to allow traffic enter outside  ip itself ?

regards

For traffic to the ASA interface No.

For SSH, Telnet or any other device behind the ASA: Yes.
