Internet Access Issues (NA)

ASmith-83 — Tue, 12 Mar 2019 05:36:22 GMT

Hi All,

I have setup a ASA in an LAB environment, and I am having issues getting out to the internet from one of my hosts behind a management subnet. I can ping outside from the ASA but from inside the network there is no internet connection

below is the config:

ciscoasa# sh run
: Saved
:
ASA Version 9.1(2) 
!
hostname ciscoasa
enable password ytjhklhj;kkjjhlnj;k encrypted
xlate per-session deny tcp any4 any4
xlate per-session deny tcp any4 any6
xlate per-session deny tcp any6 any4
xlate per-session deny tcp any6 any6
xlate per-session deny udp any4 any4 eq domain
xlate per-session deny udp any4 any6 eq domain
xlate per-session deny udp any6 any4 eq domain
xlate per-session deny udp any6 any6 eq domain

I have a host on the management network 10.10.150.180 that can't get to the internet. I am sure that there is a NAT issue, but I am not sure where.

Any help would be appreciated.
Thank you

hi there,

try this please.

object-group network obj_10.10.150.0_23
network-object 10.10.150.0 255.255.254.0
nat (outside, MGMT) dynamic interface

Let me know, if this helps.

Thanks
