I have Sonicwall 2040 Pro, Firmware Version: SonicOS Enhanced 188.8.131.52-20e ROM Version: SonicROM 184.108.40.206
I have nothing but default fw/nat rules/options set as I only made one server public visible
[NO] Enable 802.1p tagging
Interface MTU: 1500 [YES] Fragment non-VPN outbound packets larger than this Interface's MTU
X0 LAN: [NO] Enable 802.1p tagging
I did not enable BWM on WAN interface therefore I do not have bandwidth management rules in effect at all.
LAN > WAN 1 192.168.2.200 (serverPC) Private Any Any Allow All
[this entry has DSCP and 802.1p Marking Settings action set to PRESERVE]
I noticed one thing that I not quite understand.
Let's say I have two machines, 1:a desktopPC and 2:a serverPC on the same X0 LAN subnet. ServerPC is visible in public (NAT/Fw rules).
Now: if i'm downloading 1gb file from external server (http://www.thinkbroadband.com/download.html) both to desktopPC and to serverPC at once bandwidth is OK.
while i'm downloading 1gb file from external server (http://www.thinkbroadband.com/download.html) to desktopPC and on some point my serverPC starts to sending it's own 1gb file to the world on port:80, my desktopPC active download connection drops nearly to 0b/s and disconnects.
Am I missing someting?
