i recently changed a router and T line and copied the tunnel code to the new router.

i need pc's on LAN1 to ping pc's on LAN2.
what i have now is just the routers are able to ping everything everywhere. but not the LANs.

from router #1 CLI i can ping 192.168.1.1 or any device on its network
and
from router #2 CLI i can ping 172.16.1.2 or any device on its network

but locally on the network devices in the router #1 network side:
i can not ping the router #2 network devices (pc in LAN1 can not ping a pc in LAN2). and vice versa.

=====IP Legend=====
(did a replace on the first three nums of each)

Router#1 Serial IP 111.111.111.202
Router#1 IP 222.222.222.2

Router#2 Serial IP 333.333.333.122
Router#2 IP 444.444.444.160

on your C1-1841 you don't have a crypto acl 108
Code: 
crypto map vpn 10 ipsec-isakmp
 set peer 10.10.10.2
 set transform-set s1s2
 [b]match address 108[/b]

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

nice catch.
i added:

access-list 108 permit ip 172.16.0.0 0.0.7.255 192.168.1.0 0.0.0.255

same behavior still.

does this help?

change this
Code: 
access-list 109 deny ip 192.168.1.0 0.0.0.255 172.16.0.0 0.0.7.0
to this
Code: 
access-list 109 deny ip 192.168.1.0 0.0.0.255 172.16.0.0 0.0.7.255

changed AL 109 to:

access-list 109 deny ip 192.168.1.0 0.0.0.255 172.16.0.0 0.0.7.255
access-list 109 permit ip 192.168.1.0 0.0.0.255 any

didnt change the behaviour of the vpn.
