Cisco ASA 5005 LAN-LAN with NAT
|
|
I am trying to setup an ipsec tunnel. One of the requirements from the
people we are connecting to is we must appear to source the tunnel
from a public IP instead of the private ip of the box. I do not know
what model device they are using but I do know it is a checkpoint.
Ours is a Cisco ASA5505. Our config looks like this.
The other side uses a checkpoint and their hosts are also Nat'd. For the
purpose of this post I will call them Remote Peer1 and
Remote Peer2. Their Checkpoint VPN will be called Checkpoint Firewall
Remote Peer1 Static Nat to 2.2.2.2 --> Checkpoint --> ASA5505
--> Our Local host Static Nat'd to 3.3.3.2
Remote Peer2 Static Nat to 2.2.2.3 2.2.2.1
3.3.3.1
Am i missing something?
Thanks in advance,
Steve
