While I''m in temporary retirement, I''ve decided spend a little time experimenting with new things and making some updates to the web site. The biggest result of this effort to date has been: http://shorewall.sf.net/Shorewall_Squid_Usage.html This outlines how to use Squid as a transparent proxy running on the firewall, in the DMZ or in the local network. In the latter two

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

Two quick questions to the group: Anyone seen this before: Jan 14 02:55:45 gw1 kernel: Shorewall:all2all:REJECT:IN=eth1 OUT=eth0 SRC=66.58.99.83 DST=170.224.8.51 LEN=52 TOS=0x00 PREC=0x00 TTL=63 ID=38676 DF PROTO=TCP SPT=1735 DPT=80 WINDOW=5840 RES=0x00 SYN URGP=0 I mean my web server is trying to replay to some external host 170.224.8.51 (p.moreover.com) for some reason. What could be? It

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

Can someone help me with this problem: My host on the DMZ is inaccessible from the WAN on port 25. I tried to telnet but getting: $ telnet 66.58.99.84 25 Trying 66.58.99.84... telnet: Unable to connect to remote host: No route to host My shorewall/proxyarp is: #address interface external haveroute 66.58.99.82 eth1 eth0 No 66.58.99.84 eth1

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.

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

Hi My situation: I have two pc''s with public ip''s (192.159.56.206(webserver) and 84.196.123.65(mail-gateway)) in the dmz. The firewall (84.196.123.66) is configures with proxyarp, so nothing is changed on the pc''s from when they were not behind the firewall (i.e. they don''t have the firewall as gateway (and they each have different gateways, only 84.196.123.65

Hi, I have a proxy/firewall, I want to dnat requests for 193.205.140.106 on port 443 towards 10.2.15.23 and requests for 193.205.140.106 on ports 4330 and 3389 towards 10.2.15.25, these rules must apply from internet, loc and fw (some client use a proxy on fw to reach these servers) I have tried with the following rules: DNAT net dmz:10.2.15.23 tcp 443 -

Hi everybody! I''m very happy with shorewall, seems to safe my computer well, a little bit to well. But i''m sure it''s a mistake of mine: I can''t get edonkey working! They say that edonkey needs the following ports enabled: 4665 udp in / out 3665,4665,7665,8665 udp out 4661,4662,4666 tcp in thats what i wrote in the rules file: ACCEPT fw net

Hallo, i have a problem to configure shorewall to enable scanning over the network with sane. The scanner is located at the firewall hosts local interface.

I''ve got a linux router pushing 600-1000 pppoe connections through it. I''m getting a screen error "Neighbor Table Overflow" after this box has been up for between 1 week and 1 month. When this is happening, routing slows to a crawl if at all. Then dies. I''ve added: # Added to stop "neighbor table overflow" messages in the kernel

Dear List! I use a shorewall 2.0.8 on a Debian sarge system. I use a DSL connection to the Internet (ppp0 - eth1 to the modem) and a bridge to the local lan. The bridged config i''ve made with bridge.html from the shorewall site. The Bridge is between local net and a openvpn tap device. This works. I ccan make tunnels, and a can make a lot of things through the firewall. I can get a list
