I have a PIX 515E which is connected to three networks. The first network is the LAN, the second network is the DMZ and the third network is the outside. I have a web server in the DMZ which I am trying to back up using an ArcServe server on the LAN. The LAN and the DMZ are both 100Mbit full duplex
Backing up LAN servers I get an average of 400MB/min during the backup, while backing up from the DMZ to the LAN via the PIX I get an average of 9.5MB/min.
Is there a reason that the speed difference is so great? The backups are taking forever to complete.
It would appear that the problem lay with the duplex that was set on the firewall. I changed it from full to half and the speed increase of a file transfer was 100-fold. I yet have to see the result of a backup run across the firewall but I am guessing it will be greatly increased. I still see a lot of collisions so I will do some more tweaking of the PIX using the document you pointed me to. Thanks again for your help
