static; can't ping

[naingtan]

Eventhough, i use one to one nat from public ip address to private ip address (DMZ or inside),
static (inside,outside) xxx.xxx.xxx.165 private_IP.112 netmask 255.255.255.255 0 0 and access list as
access-list outside_access_in permit icmp any any
i could not ping xxx.xxx.xxx.165

but i can ping another xxx.xxx.xxx.162 see the following config:

HI.

> i could not ping xxx.xxx.xxx.165
Seems like a routing issue.
Check with your ISP or yourself (if you manage perimeter routing).
Check ip addressing, subneting and routing in router configuration.
Try also to reboot the router or to clear the ARP cache.
You can also try traceroute from a remote host on the Internet (using dial-up for example), and/or from a site like:

http://www.samspade.org

***

Some additional notes on the configuration:
The pix has fixup support for ftp, h323 and other protocols, so you do NOT need to open additional ports, the pix should do it for you in a more secure manner.
This lines can be removed, and then check if things are working:
> access-list outside_access_in permit tcp any eq ftp-data host xxx.xxx.xxx.163 eq ftp-data
> access-list outside_access_in permit udp any host xxx.xxx.xxx.215 range 1024 65535
and some more...

> name 64.12.163.0 ICQservers
> access-list intf4_access_in deny ip host xxxxFTP2 host ICQservers
This is wrong. I think that this is the correct line:
> access-list intf4_access_in deny ip host xxxxFTP2 ICQservers 255.255.255.0


***
> access-list intf4_access_in permit ip any any

You have a dedicated VPN server on intf4, this is nice.
I suggest that you limit the access that VPN clients have by using a more restrictive access-list on "intf4", unless you must give VPN clients full access to the whole internal network and the Internet (from intf4).
