Hello,
My company recently switched from PIX506E to ASA5510.
ASA5510 works good except the pc wich static IP cannot browse Internet and ping outside ip. (All fixed IP pc except Windows PDC 10.0.0.6)
PC with dynamic IP assigned by Windows Server is OK.
Could you take a look at the following config of ASA5510?

Mike,
A couple of things worth checking to see what is really failing and then we can work our way up from there...
1) From that host can you resolve DNS?
- What is that host's DNS server
- Does 'nslookup google.com' work?
- Does 'nslookup google.com 4.2.2.2' work?
2) Do you see any SYSLOGS generated on the ASA related to that hosts IP address 10.0.0.6?
3) Does that host (10.0.0.6) have the right arp entry for 10.0.0.1?
- On the host issue 'arp -an' and compare the value (if any) for 10.0.0.1 to the interface MAC address seen on the ASA if you run the command 'show interface Ethernet0/1'
4) If this is a recent migration, the upstream router (your ISP) may have the wrong MAC address listed for the translated address of 10.0.0.6. You can try reloading the upstream router to clear this condition. (An enhance bug was filed to help prevent this issue in the future, it is not yet integrated into any code tho... CSCsy85614 ).
Let me know the results of the above points and if the above helps you track down the issue,please marked this question as 'resolved'.
-Magnus.

Thank you for your reply.
After I talked with Telepacific, ISP, it looks like it's not corrupt arp.
Arp will eventully flushed out with TTL and no changes made for static ip pcs.
When I load ASDM, the Remote Desktop firewall rule to one of static IP pc shows hit count of 0.
It sounds more like translation issue.
I am not sure of my config cause I experienced there is always little different setup from version to version.
Your proposal of 1 and 3 all works fine.
07-23-2010 05:59 PM
This could be a translation issue, you might be going out using nat exmption (nat 0).
What are the dhcp assigned ip addresses that don't work?
PK
07-27-2010 05:46 PM
Yes it feels me it more like translation issue.
DHCP server is 10.0.0.6
One of the fixed IP pc is 10.0.0.34 which has public IP assigned to it with static command.
Remote RDP to it does not work and ASDM shows no hit!
07-27-2010 10:41 PM
Hello,
So, you are not seeing any hit counts for the access-lists corresponding to these public IP's? If that is the case, the firewall is not seeing any packets on the outside interface for those IP's. Can you try adding a generic rule for one of the IP's (access-list
Hope this helps.

NT

Hello,
The issue seems to be with your ISP router having wrong ARP entry for the public IP addresses that are mapped to the devices with static IP addresses on the inside. I would suggest you reboot the ISP router (or talk to ISP and have them flush the ARP Cache) and see if that fixes the issue.
Hope this helps.
Regards,
NT
