cisco 881 vpn server connected, but can not ping Lan interface

[yayasolenet]

I've configured a lot vpn server for 857/1800, etc. But this has never happened.

I configured 881 as VPN server using CP.

Shared key, local group and local user authetication with split route.

Local pool 192.168.100.1-254

I have acl for telnet which allows local pool IPs.

I have acl to deny local network to local pool IPs for NAT.

I've deleted the whole settings and re-run the wizard. It's still the same thing. I can connect from the VPN Client, but no traffic going through.

Attached please find more debug screen shot.The problem to me is isakmp with DPD. But why it is dead? Why no response from the server? If it is an error, why connection has no problem.

Somebody please help.

More infomation.

The connection did not insert a route in router's routing table.

The router is cisco 881and it has 1 VPN module when I do "sh ver".  But I am just use Easy VPN Server. The IOS is 15.0(1)M3.fc2. C880-DATA-UNIVERALK9-M.

Is there any bug for VPN in this IOS?
