Hi Segun,
ok, thanks. I don't want to encrypt all raffic, only the traffic to
the loopbacks.

Hi Simon,
The getvpn acl need to match intresting traffic-since there's a
default deny after ur acl you really dont need to put the 3 deny
statements you have there.
You would need to put a deny before permit if there are specific IPs
within your permit network that shld not be encrypted. And in ur
example, the traffic u denied does not match any of the permitted
traffic, therefore i do not think its necesary.
Regards.

Subject: [OSL | CCIE_Security] Clarification about GET VPN.
Hi,
I'm setting up an GET VPN environmet at a security ProtcorLabs pod. My
scenario looks like this:
Used devices: cat2, r1, r7, r8
cat2:
vlan 2, int vlan2: ip addr 2.2.2.254
vlan 7, int vlan 7: ip addr 7.7.7.254
vlan 8, int vlan 8: ip addr 8.8.8.254
Server: r1
Clients: r7 and r8
r1: fa0/1: ip addr 2.2.2.1, lo0: 22.22.22.1. Default route to fa0/1.
r7: fa0/0: ip addr 7.7.7.1, lo0 77.77.77.1. Default route to fa 0/0.
r8: fa0/0: ip addr 8.8.8.1, lo0 88.88.88.1. Default route to fa 0/0.
I want to protect traffic between the loopbacks of my router. But I'm
not sure how I have to configure my ACL to only
match this traffic.
The Cisco documentation states: "Ensure that your ACL starts with a
deny statement if all traffic does not need to be encrypted."
So in my case, this would be the following ACL?
ip access-list extended GET_VPN
deny ip host 2.2.2.1 any
deny ip host 8.8.8.1 any
deny ip host 7.7.7.1 any
permit ip host 22.22.22.1 any
permit ip host 77.77.77.1 any
permit ip host 88.88.88.1 any
TIA.
Have a nice weekend
Simon
