hello,
first of all, sorry for my bad english. actually i'm french and above all an absolute beginner in ASA Cisco
i'm trying to install a Cisco ASA 5505 for a client and it's impossible to access to internet (in fact, the original subject is about creating an IPsec site-to-site VPN, but I can not even access internet so...)
Below my setup
From my client I cannot ping the outside interface, but I think it's normal.
From the firewall, I can ping the ISP Modem and Google DNS server 8.8.8.8
I configured the Asa with the wizzard tool
see below the configuration:

Hi,
You dont have a default route
Add this
route outside 0.0.0.0 0.0.0.0 192.168.167.254
I am not sure how your ISP modems NAT and routing is configured so you might want to configure Dynamic PAT for your LAN users on the ASA if the "route" command isnt enough.
global (outside) 1 interface
nat (inside) 1 192.168.3.0 255.255.255.0
Also your ACL only allows ICMP from the LAN. I would suggest adding the following
access-list inside_access_in permit ip 192.168.3.0 255.255.255.0 any
Also add
policy-map global_policy
class inspection_default
inspect icmp
inspect icmp error
Hope this helps
