Internet Access Issues (NA)

ASmith-83
Level 1
Level 1

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

Are you interfaces and security-levels configured correctly?

interface GigabitEthernet0/0
 nameif outside
 security-level 100
 ip address 1.1.1.1 255.255.255.252
 
interface Management0/0
 nameif MGMT
 security-level 0
 ip address 10.10.150.0 255.255.254.0
