Assuming you want the ASA to use PPPoE: http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080ab7ce9.shtml

Otherwise, could you give some more detail?

Hi,

I'm using the adsm, when I try to configure the interface for pppoe I don't see (use pppoe). The outside interface is configured for vpn site-to-site.

I think you might need to upgrade your software. I'm not able to check right now from what version pppoe is supported, but i'll let you know.

Ok. I'll try the command instead, does that have anything to do with IOS version. Also, can I use the managment interface for pppoe.

I've checked, you will need version 8.x for the asa to be able to act as an PPPoE client... (So doesn't matter if you use asdm our CLI, in your version the option isn't there yet).

You can use  the managment interface for that if you remove the 'management only' option from it, it will then act as a regular interface.

Also keep in mind that from version 8.3 NAT has been completely changed. So you might want to start with 8.2x before having to worry about a completely changed nat implementation. If you do upgrade to 8.3x though, your current nat statements will be automatically converted.

So you managed to upgrade the ASA?

About the disabeling, are you sure you are logged on at the highest (non restrictive) level? -> level 15 acces.

I didn't upgrade the ASA yet.

I'm logging with level 15 admin, and I can't uncheck the management option.
