DMZ hosts gateway
Hi everyone, I have a question regarding the default gateway for hosts on DMZ zone. I moved servers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external

Two web servers on DMZ zone with private ad dresses. How to?
That log message looks like someone (or some program) is trying to browse to moreover.com from your web server machine--it''s not a reply to an external request. You''d see messages like that if you were running some sort of HTTP proxy server (like Squid) on that box (although they''d likely be to multiple IPs, unless your users only browsed to p.moreover.com). It could

HTB. QoS and Shorewall
Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

FW: SMTP traffic gets blocked
Anyone, willing to take a lead on this one, since Tom is taking a rest: " I am hosting all servers by myself. I have five static IP addreses with a DSL line. My DSL router from the ISP provider is configured as bridge, so no traffic is filtered. I checked the logs and getting: Jan 5 23:05:12 gw1 kernel: Shorewall:all2all:REJECT:IN= OUT=eth0 SRC=66.58.99.86 DST=216.35.73.164 LEN=68

Hardware advice please?
I am quite new to Linux and have moved (almost) from a windoze NT4 environment. My present configuration is running SuSE V 8.0 with KDE3.0.5 desktop on two machines, connecting with Samba to an NT4 PC, and an occasional laptop or other PC that connects locally to the network. After a deal of searching, researching, and seeking advice I have decided to use Shorewall as my firewall.

Using private & public addresses together i n the Shorewall''s DMZ zone
To rephrase the question, "Can I use masquerading and proxy ARP in the same zone simultaneously?" It''s not a stupid question--I couldn''t see any reason why it wouldn''t work, but I had actually try it out to convince myself that it did (which isn''t a bad thing to do before posting the question to the list, by the way). In any case, the answer is

Mandrake 9.0 won''t ping ...
When installing Mandrake 9.0 with the higher security option you cannot ping any of it interfaces, localhost (127.0.0.1) included. All other connections to the system are fine, e.g. ssh, www, squid, etc. "shorewall clear" doesn''t help. Does anyone know how to turn this off for at least localhost and eth1?? Yours truly, Ben

Shorewall config format
Hi, I''m a long time shorewall user and I like it very much. There is only one thing were I''m not always happy with: the config files. There has been discussion on the list about the comments in the files. My concern is that I loose overview over my configuration because of the many config files. Of course there are advantages too but I thinking wether another config format would
