Hello everybody,
I have the following configuration:
DMZ (10.0.0.2, running Win2k3) eth1 (10.0.0.1) ASG 7.501 (192.168.0.1) eth0 storage server (192.168.0.2, running Linux)
The DMZ is running in a XEN environment, the link between 10.0.0.2 and 10.0.0.1 is a dedicated VLAN (port-based).
On firewall, the 10.0.0.2 is allowed to access 192.168.0.2 over iSCSI (port 3260).
I can connect from DMZ to storage server with help of Microsoft iSCSI initiator and I am able to copy files too, BUT: if I copy a file larger than ~35 MByte, the opened iSCSI connection crashes, means the transfer of the file cancels and underlying services are crashed although.
After that I am not able to re-open a connection from DMZ to storage server.
You might say: Woah, this is a fault of Windows - this was my first thought too.
But I tried another configuration (direct DMZ (10.0.0.2) storage server (192.168.0.2), port based VLAN) and everything works fine.
So I assume that the ASG / packet filter has a problem with high traffic, cache overflow or some kind of that.
Do you have any suggestions or ideas?
Thanks in advance,
Christopher
