hi,

could you check the arp entries for pix on ISA, and the arp entry for ISA on PIX. then match the arp entry with the MAC addresses of the corresponding device

also is there any firewall? may be ISA have enabled firewall, so that only initiated traffic can be received

thanks

Nadeem

Hi nkhawaja

Not for sure what you are asking.Could you please be more specific.

Thanks...

type "show arp" on the pix and record the MAC address of the server. then type "arp -a" on the server and check the mac address of the pix.
