Cisco ASA in routing mode : WAN to LAN traffic allow query

[KumarMH06540]

Hi,

I have cisco ASA configures on Routing mode, with all default settings, Inside and outside interface.

How do i allow traffic from outside to inside, Need your suggesting's and guidance

1) Allow all outside to inside

2) Allow specific IPs with specific destination ports outside to inside.

Look like your requirement confusing here.

1) Allow all outside to inside    --  allow inside ? what networks? ( you mean any Public iP address can access internal address, based on static mapping ?)

2) Allow specific IPs with specific destination ports outside to inside. - this required static or dynamic natting? ( do you have enough Public IP address?

i suggest some URL you need

1. basic setup with working inside to out NAT, so internal LAN user can access Inernet other resources.

2. Out side to inside

you can do based on the IP address available and requirement. for understanding below URL help you :
