Hi, Well, if the lost ARP entry is the NAT one, I think you could enter it manually in the Cisco router configuration (The MAC address of the NOKIA box). If the lost MAC is the own AS400, you could make a static entry in the NOKIA configuration. However, I don´t know why could this behavior be, I think you must review the LAN switches.

And now the problem is the ARP of IBM AS/400 often get lost by itself so it can not access to outside world and also can not be accessed from outside world. I do not know why it can be happen ?? is there anyone explain to me about this ?? So how is the step I have to take to solve this problem ?? Is there any alternatif solution beside using Static NAT so I still make my IBM AS/400 can be accessed from outside world ?? I really need a help for this, Thank you for your help and attention Regards, Ario --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
