I have about a hundred NATs in my PIX515E. There is just this one NAT that will not stay. This is the senario:
Client FTP's into our network. We NAT their IP before letting them enter. They connect and download there files and then disconnect. The next time they try to connect, it just times out. We have to connect to them to re-establish the NAT, and then they can connect again.
Like I said, this is only happening to this one NAT. I have also set the xlate timeout to 144 hours and it still doesn't hold. Any thoughts??? Thanks.
