Hello
I use Cisco ASA 5510 IOS 8.4
I have cratd interfaces, access-list etc. but I can reach any adresses from inside to outside end vice versa.
I don't use NAT (outside and inside have not mapped adresses).

Do I have create NAT ?

Hello Aleksander.
You will need to have NAT between your two nameifs as they are configured with different security levels.
If you want to avoid using NAT, what you can do is set up Twice NAT (Manual NAT) to translate your IP addresses to themselves. It's similar in function to NAT Exempt in pre-8.3 syntax.
Please reference this document for details:
https://supportforums.cisco.com/docs/DOC-11639
Hope that helps.

Hello
I add the folowing lines :
object network wlall
subnet 0.0.0.0 0.0.0.0
object network oball
subnet 0.0.0.0 0.0.0.0
nat (inpa,outpa) source static wlall wlall destination static oball oball
nat (outpa,inpa) source static oball oball destination static wlall wlall
But still I have errors 106016 and 609002
Could I ask for any advice ?
Regards
Alex

With your ASA-version you do not need NAT. If you don't specify NAT, then the ASA will route the traffic as a "normal" router would do.
One problem is in the redundant-config. All redundant members have to share the same media-type, speed and duplex. In your config you mix 100 MBit-interfaces with 1000 MBit-interfaces. You have to combine Eth0/0 and 0/1 in the first redundant interface and Eth0/2 and 0/3 in the second redundant interface.
Regarding your log-messages:
609002 is just informational, you should see a corresponding "Build local host". For message 106016, mor iformation is needed on how you test traffic through the ASA.

I have removed second interfejs from Redundants.
I have remove all nat writes.
I set the same security level an both redundant interfaces.
Still errors 302014
Have any idea ?

I set the same security level an both redundant interfaces.
do they need to commnicate? Then you need
same-security-traffic permit inter-interface
Still errors 302014
That's not an error message.
How do you test?

1)
I try to ping from outside network an interfejs on the inside side.
I can ping outside interface
2)
From outside network I can rnot each by telnet ASA - I of course added telnet networks to config
By the way I add
same-security-traffic permit inter-interface
but with no effects

I can ping outside interface
That's not supported on the ASA. Try to reach an inside host. And for using ping, you should add the inspection of icmp-traffic:
policy-map global_policy
class inspection_default
inspect icmp
2)
From outside network I can rnot each by telnet ASA - I of course added telnet networks to config
Telnet is not allowed on the outside interface on the ASA (it's by design). Use SSH instead.
