split tunneling
Right now my asa 5505 is running split tunneling so my internet traffic goes out the local ISP. I want to change that so all traffic from the site with the 5505 goes to our corporate location. Below is my current access list config on the asa.
access-list IPsec-traffic extended permit ip 10.30.1.0 255.255.255.0 10.1.0.0 255.255.0.0
access-list nonat extended permit ip 10.30.1.0 255.255.255.0 10.1.0.0 255.255.0.0
access-list IPsec-traffic extended permit ip 10.30.1.0 255.255.255.0 10.1.0.0 255.255.0.0
access-list nonat extended permit ip 10.30.1.0 255.255.255.0 10.1.0.0 255.255.0.0
can we have the full config please minus your external ip's ;0)
I think you just need to remove these two lines?

You should change the following;
This determines what traffic traverses the IPSEC tunnel.
access-list IPsec-traffic extended permit ip 10.30.1.0 255.255.255.0 10.1.0.0 255.255.0.0
TO
access-list IPsec-traffic extended permit ip 10.30.1.0 255.255.255.0 any
Update the following line to increase the no-nat scope.
access-list nonat extended permit ip 10.30.1.0 255.255.255.0 10.1.0.0 255.255.0.0

Am I going to have to update my access lists on the firewall at the corporate location that the ASA terminates into?
what hardware does it terminate to?

Can you post the 515 config?
You will likely need to increase the NAT scope to include the remote network.

I dont agree with lnavin's comment
surely all that would do is allow any ip to traverse the tunnel?
I dont claim to be an expert but have configured quite a few ASA 5505 / 5510 / 5520's over the past few weeks.
My understanding is that split tunneling applies to the client software, and achieved using security policies, like this...
group-policy vpnclientgroup internal
group-policy vpnclientgroup attributes
dns-server value 192.168.1.10
wins-server value 192.168.1.10
split-tunnel-policy tunnelspecified
split-tunnel-network-list value Split_Tunnel_List_ACL
vpn-tunnel-protocol IPSec
default-domain value YOURDOMAIN.com
Someone please correct me if i am way off...
What your trying to achive is forcing all traffic from the ASA to go out via the Pix right?
surely thats just routing?

ASKER
yes that is correct. I want internet bound traffic to go through corporate instead of the local ISP.
OK I think you need the split tunnel commands but using
split-tunnel-policy tunnelall
I got it wrong about only being for the client, it does actually work with site to site

how would I set this up for my scenario. I have 1 pc hardwired into the ASA and want the internet traffic from it to go through the tunnel to corporate.
Where do I apply the "split-tunnel-policy tunnelall" command?
