kindly i need to ask about the below senario
i need to configure a vpn site to site over adsl between two sites
the problem is only with the site which have a cisco router model 881
this cisco router 878 have only 4 swithport and no external interfaces like adsl or wan it only have g.shdsl and isdn
my cisco router is connected to an external adsl home router through one of the switchports of the cisco i have done all the site to site configuration but still confused where to apply the crypto Map at which interface of the cisco 881
