are visible through virtual hosting through a web re-director.
3. Presently the proxy server runs in a transparent mode, i.e., all web

DNAT Problem
Hi,
I have a client behind shorewall which has 2 IP:
192.168.8.35 is the real IP and 192.168.8.37 is the virtual IP.
I have added DNAT rules into shorewall:
DNAT net loc:192.168.8.35 tcp 11008 - 1.2.3.4
DNAT net loc:192.168.8.37 tcp 55000 - 1.2.3.5
1.2.3.4 and 1.2.3.5 is virtual IP

Packet Not 100% Received
I have problem with my shorewall. We are now doing some stress test with a http application behind the shorewall. Firstly we send 10.000 requests to a http based application with no firewall. It can received 100% requests. But when we put shorewall in front of it then it stats to loose requests. Is there any packet limitation from shorewall all it''s about conntrack? Thanks for the reply.

Statistically detecting thresholds...
Rers:
I have some ecological data (stream velocity vs. % cover of submerged
weeds) that shows strong evidence of a thresholding step-function, e.g.
below some velocity, % cover ranges from 0% to 100% (with no apparent
relationship to velocity within this range of velocities), but above a
certain "threshold" velocity, the % cover does not appear to exceed,
say, 10%. There are good
