I have two failover PIX firewalls that were just updated to v6.3(3). Now, when a user goes through the PIX to the FTP server in the DMZ, it takes a really long time (40+ secs) before the user is presented with a login prompt.
Turning off fixup for FTP does not affect this delay. Otherwise, things seem normal and other FTP operations are speedy. Also, when device within the DMZ ftps to the server it doesn't have this issue... so only traffic through the PIX seems to display this behavior.
Anyone see anything like this before?
