Required your suggestions.




Re: Does 1841 support IPSec vpn ?

Hi Siva,

The current IP base package that you have doesn't support IPSec.

You need to have a Advance security package for that.

Check out this link to understand the IOS packaging details and the feature set hierarchy

To understand more on IOS packaging, visit this QA section

Use the feature navigator at the following URL, using which you can find out features supported based on platforms, the current ios image that you have etc.

A Very usefull tool, to understand what is currently supported with your devices/ios and how you can plan for upgradation.

AIM is optional. For additional throughput and other benefits your can opt for it.
