First of all I would say that the software release is pretty old. You are
running 7.4.01 and the current patch release out of the 7.4.01 stream is
7.4.01l which means there are a,b,c,d,e,f,g,h,i,j,k and l after your
release as patch releases. 12 patch releases... quite a lot. I would
suggest to have a look at the patch releases in between 7.4.01 and
7.4.01l. <br><br>
I do not get the whole setup based on your email below. The problem
occurs in case you try to download something from the internet via proxy0
or proxy1 - correct? The proxy IPs are .86 and .87 - what is the default
gateways from the proxies point of view? I do not see any redundancy
configured looking at the configuration of the XL below - given the fact
that you are talking about 2 SI XLs I would assume it is simple to run
into some kind of situation with a L2 loop without configuring any
redundancy. Do you mind to share a network diagram and maybe the
configuration of the second XL?<br><br>

I want to use 2 ServerIron XL (stackable) for redundant loadbalancing 2

Anyhow, i'm new to this and run into a lot of problems i just want to
begin with a small config, but i still got trouble with connection
speed.<br><br>
I just configured the basics with 1 SI:<br><br>

thats really basic i think, 1 Net
(<a href="http://79.45.16.64">79.45.16.64</a>
<a href="http://255.255.255.192">255.255.255.192</a>), 2 server directly
connected to the SI (port 9 and 10), 1 uplink (port 15, i although tried
"server router-ports 15"..didnt make a change)<br><br>
Now the Problem:<br>
Transfering data from proxy0 to proxy1 and back is ok and fast, about
11Mb/s.<br>
But downloading a file on proxy0 or proxy1 from the internet is terrible
slow, bout 150Kb/s :(<br><br>
If i connect the server directly with the uplink i can get the full speed
of my hoster, bout 8Mb/s.<br>
Whats happening??<br>
I think the SI acts here like a normal switch for the real servers, why
is it that slow? <br>
Its not usable for me :(<br><br>
Perhaps interessting: if i download something here at home from the VIP,
the speed seems to be better, i cant absolutly say cause of my slow line
here at home.<br><br>
But speed from servers connected to the SI and using its uplink port to
the internet is very very slow.<br><br>
Anyone can pls explain that for me? Im in desperate need of help
here..<br><br>
