Easy VPN to a 2821 behind another Cisco router...

Hi guys,

     I am sure this has been asked before and if you can point me to the right link, cool....

Anyways, here is the link / example I am following:

http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6635/ps6659/prod_white_paper0900aecd80313bdf.pdf

So, what changes are needed to the 2821 config that is behind another Cisco router?  And what static ports should be opened on the MAIN Cisco router that is in front of the 2821?

Thanks for eveyone's time!

Hi Jason,

There is a nice article about it:

http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080094ecd.shtml

You need to open:

udp 500/4500

esp

Thank you
