selective redirect
Hi,
I am trying to redirect my subnet thru squid and it seems to be working.
However I decided tu exclude two hosts from the redirect (ie acces the
net directly) and can''t manage to achieve that. I am using the following
rule:
REDIRECT loc:!192.168.13.48,!192.168.13.200 3128
tcp 80 -
With this rule everything gets redirected thru squid. I also tried:

Hi, I have shorewall 2.0.8 installed on a linux box. Recently I moved
to a setup with a front/back firewall
With shorewall acting as a front firewall and M$ ISA Server 2004 acting
as a back firewall. I turned all ''intrusion alerts''
On at the ISA server expecting not to get any since shorewall should
block everything.
Now to the problem:
I am getting quite a few alerts

follow-up on ISA intrusion detection
Hi, I wrote a mail a few days ago concerning my setup with a front/back
firewall, shorewall being front and ISA server 2004 acting as back
firewall.
I said that ISA server is logging some "intrusion attempts" namely
requests coming from external interface to the internal network.
As this shouldn''t happen (all intrusion attempts should be stopped by
shorewall) I begun to

OT: Why slow mail-check on wireless?
Ok this is admittedly OT, but when you want network advice you go to
where network gurus hang...
When popping mail from my primary mail server (Linux) from my linux
laptop a simple mail check takes 15 seconds to connect when using
a wireless nic (802.11g) and 1 second using the hardwired nic.
Popping my backup mailserver (also linux) which is sitting RIGHT BESIDE
the primary takes one second

ProxyARP in a Routed environment
Hi,
In a routed network setup , is it possible to use ProxyARP given the condition that the shorewall
external interface and the DMZ interface are in a completely different network . That means the gateway of the External interface and the hosts in ProxyARPed DMZ zones are in different network.
eth0 ---in 220.227.X.Y/30 -- shorewall external interface
eth1 ---in 220.227.A.B/27 -- shorewall

proxyarp <--> OpenSwan VPN/Internet
Our VPN runs for 3 months very well with a minimum of traffic <100 kbit/s.
Only DNS Zones and nagios passive checks were transferred. Everything seems
to work.
Left side is x.x.x.14 (host 1)
Subnet 10.0.0.0/24
openswan 2.4.4
shorewall 2.4.2 & iptables 1.3.4
