1720: VPN Client to Router Question

A client of ours recently asked us to configure the VPN capabilities of their Cisco 1720 router. They wanted their traveling employees to have a simple way to access the network.

crypto dynamic-map dyna 10

set transform-set mypolicy

!

crypto map test 10 ipsec-isakmp dynamic dyna

no ip mroute-cache

crypto map test

Re: 1720: VPN Client to Router Question

Make sure you’re on very current IOS and you follow this example http://www.cisco.com/warp/customer/707/oddconfig.html I can’t tell from what you posted what your ACL’s look like or the version but if you go through this sample, you should be up and running.
