Any duplicated entries for a specific access-list in the pix configuration?... Check this into nat, aaa, access-group, vpn, etc...

Hi

The errormessage is commonly displayes when you are using one access-list for two purposes:

Like the Vpnis used for

- nonat (nat 0)

AND

- to specify the traffic wich should be encrypted.

Split this up in two different access-list one named ex: "nonat" and the other ex."ipsec" with the same IP address space.

The "nonat" ACL should then be used to the nat (0) statement,

The "ipsec" ACL should then be used to specify the encrypted traffic.

This will solve your problem.

Re: configuring PDM on 515E 6.3(4)

thanks, but just curious. if everything is running okay and i don't see any problems on the pix meaning everything works as it's suppose to be then why does PDM has a problem is understanding this configuration.

Does it mean that there is a problem and i am not yet aware of it or will it make a problem which i cannot forecast???

Hi

There is no error on the configuration. PDM just dont support it, and needs different access-list for the different "tasks".

You can keep it as it is, but I believe this limit the PDM functionality. There is no Firewall config error, in fact before PDM was introduced you saved configuration-lines by using the same acl for different tasks....

Use 2 different access-list names and your PDM-Problem is solved.
