ASA5505- PAT



We are replacing PIX 501 with ASA 5505. We are able to get the L2L VPN up but not the Internet access. When we try to add the NAT (Inside) x statement firewall gives warning message saying missing outside command. But If we add the Outside command to end of NAT statement we loose L2L vpns but Internet access works. Below is the config ..

global (outside) 1 interface

nat (inside) 0 access-list nonat

nat (inside) 1

Below are the Warning messeges

WARNING: Binding inside nat statement to outermost interface.

WARNING: Keyword "outside" is probably missing.

*** Output from config line 94, "nat (inside) 1 0...

We have tried 2 diffrent IOS


Cisco Adaptive Security Appliance Software Version 8.0(4) and Version

thanks in advance for the help.

Unless you made an error when pasted config into this forum, you need to set your security-level for outside interface to 0 and inside security-level to 100. Your above message showed outside at 100 and inside at 0.

Check to make sure that the physical interface that is your outside interface is actually configured with "nameif outside"


Hello there,

Yes, We have configured this correctly and here is the config. I guess.. no issue with that as my Site to Site VPNs are working.

interface Vlan1

description Inside

nameif inside

security-level 0

ip address 172.x.x.x


interface Vlan2

description outside

nameif outside

security-level 100

ip address 195.x.x.x


interface Ethernet0/0

description outside

switchport access vlan 2


interface Ethernet0/1

description inside

speed 100

duplex full

OK try the below:-

global (outside) 2 195.x.x.x (next unused IP address)

nat (inside) 2 172.x.x.x

then clear xlate


we have only 1 IP for this connnection and wont be able to try this.

your initial config shows:-

ip address 195.x.x.x

You have 1 IP for the interface

1 IP for the next hop routing device?

you have 4 other IP addresses?

Hi Andrew,

Sorry for confusion, this is a xDSL link and we have only Static IP.

how many static IP's do you have?

post the output of a show arp?

You only have a license to 10 inside hosts, and remote IP addresses over a VPN count as an inside host.

How many computers do you have behind the ASA?


I dont have this ASA in production right now as we had this issue. During the testing , we have only 2 hosts in network. When Licenses get over, traselation wont happen?

FYI.. our currnt pix is also has only 10 host license and all working.

Does pix and ASA work diffrenlty in terms of licesnse?

We have orderd 50 hosts license for this and will be getting it soon.



Post your current config for review - remove any sensitive information.

Also, you got any documents on how the Cisco ASA Licensing works?

Below is the ASA license matrix:-

Are you sure your outside Ip addresses don't allow for my suggestion? You have a default gateway pointing to .241 which is the first IP address in the /248 subnet? What Ip address are you using for the outside?

Its issue with Security Level and Tks for the help
