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. I haven't had much experience with the VPN aspect of routers and I hope someone out there can help me. Here's a portion of the routers configuration;



crypto isakmp policy 10

hash md5

authentication pre-share

crypto isakmp key ******** address



crypto ipsec transform-set mypolicy esp-des esp-md5-hmac


crypto dynamic-map dyna 10

set transform-set mypolicy


crypto map test 10 ipsec-isakmp dynamic dyna



interface Serial0

ip address

no ip directed-broadcast

no ip route-cache

no ip mroute-cache

crypto map test



Also, how do you specify that any client IP is accepted?

Re: 1720: VPN Client to Router Question

Make sure you’re on very current IOS and you follow this example 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.
