Dear CheckPoint Gurus...



I have a NOKIA IP530 with IPSO 4.1 and CheckPoint R61 installed. This firewall 
have 19 internal interfaces and 1 external interface with a /28 range of IPs.



The network of the users and some servers (/22), make NAT to internet in one 
IP. Last night, this nat crashed and all the internet access from this network 
stopped.



All others nat (1 to 1 for the web servers) did not stopped.



I received this message in the LOG;



DROP - "message_info: NAT Hide failure - there any currently no available ports for 
hide operation"





I have no ideas of what could be happening, because the only solution that I 
have in that hour (4:00am) was a reboot. Rsrsrs




 How many user do you have on the /22 network ?
 This seems like a resource problem, for the NAT code , no longer
 being able to map client IP's to the Natted address.
