We are getting a 7204VXr along with a new DS3 connection. Would anyone have a DS3 config to use as a template? Even better would be if it had the hardened ACL (deny private IPs, etc.) included with it. I know this is asking a lot. Any info is highly apprecaited.

Here is the config on one of our 7204's.

interface Serial1/0
description DS3
bandwidth 45000
ip address x.x.x.x
ip access-group 199 in
ip route-cache flow
dsu mode 2
dsu bandwidth 44210
framing c-bit
cablelength 100
serial restart-delay 0
no cdp enable

The config will vary slightly depending on the telco. We have another DS3 from a different telco that has scramble turned on, but you'll just have to ask your telco.

The acl on this router isn't blocking private IP's, but here is what it does block:

access-list 199 deny udp any any eq snmp log
access-list 199 deny tcp any any eq 0 log
access-list 199 deny udp any any eq ntp log
access-list 199 deny tcp any any eq telnet log
access-list 199 deny icmp any any timestamp-reply log
access-list 199 deny icmp any any timestamp-request log
access-list 199 permit ip any any

Hope this helps!
