Cisco ASA Point-to-Point Stub Configuration

All -

I have an ASA (US-HEN) on a public IP that is a fiber based connection.  Then there is a private point-to-point from the same fiber service company.  Both ASA are 5510 in routed mode.  The second location (US-LEX) used to have a site-to-site VPN over a DSL connection which has gone away.  So now there is a private point-to-point over a /32 subnet and I'm pointing the ASA at US-LEX back to US-HEN as its default gateway.  Should I put the second ASA (I'm calling this a 'stub' connection) into transparent mode as opposed to routed?

Cisco ASA Point-to-Point Stub Configuration

A quick diagram:

Internet ---- US-HEN outside ---- US-HEN ptp ( ---- US-LEX ptp ( ---- US-LEX inside

                    sec-level 0               sec-level 100                         sec-level 100                         sec-level 100

I have turned on permit inter and intra interface and the following routing exists:


1.  ip route [public IP gateway]

2.  ip route 192.168.x.x [US-LEX]


1.  ip route

Should I specify NAT exemptions in both directions for traffic?  I would think that I wouldn't need that unless traffic is about to go over a site-to-site VPN tunnel.

I was also thinking about configuring it with 'ip permit any any' statements to allow all of the traffic in/out and disabling NAT.  Really I just need it to function like a router at this point and not so much a firewall.
