Hi all, I am using the wizard to create a site-to-site VPN. Every time I set ths up I loose the internet. The 2 lines that I remove allow me back on:

no access-list inside_nat0_outbound_1 extended permit ip 192.168.30.0 255.255.255.0 any
no access-list outside_1_cryptomap_1 extended permit ip 192.168.30.0 255.255.255.0

The only part of the wizard that I am unsure of is the "protect" "do not protect" section it has 2 choices for local network and remote network. What am I supposed to choose here? When I chose "do not protect" it ays I canot chose that....An help with this wizard would be great
Cheers
 

what is your internal segment and the remote network segment? it looks like your sending all traffic though the tunnel instead of only traffic destine for that remote network like it sounds like you want to do. It would be helpful to post a sanitized copy of your config. but you probably just need to be more specific with your acl for crypto and nat0, for example permit ip local-net remote-net instead of using any. hope that helps

cheers

Just reying to get a site to site going..
 
The local network is
192.168.x.x network and the remote (peer) network is 66.159.x.x with also a 192.168.x.x
 

This will get you going fromthe cli if you want to try it that way. Just change <remote peer> to the ip of your remote peer outside ip address and update the lan segments used. hope that helps

cheers
