I want to build a robust firewall for a resort installation. The resort''s telephony is entirely VOIP, asterisk based. We have the following internet feeds: 1) 512/512 kb fixed bandwidth leased line with static IP from Telco- primary connection, expensive, to use for VOIP, VPN traffic, mail server, SSH access for remote work. Reliable. 2) 256/512 kb ADSL from Telco, not fixed IP -

Hi folks, Has anyone out there done port forwarding or DNAT for UDP packets that are normally sent to the broadcast address (255.255.255.255)? I have to support a nasty database application called FileMaker Pro (those of you who know it are probably groaning about now), which uses broadcasts to locate the database server. Theoretically, i can get around this requirement by using LDAP lookups

Hi Tom and All, I have been quietly watching the list for the last year (no new issues for me that weren''t covered in the docs or promptly "bug-fixed" by Tom. Boy, has this grown exponentially! Anyway, back to the point (the proverbial rearranging the furniture)... I have been evaluating Mandrake''s MNF as an upgrade for my Firewall box. If I do this( and even if I

Hello Everyone! I am using shorewall-3.0.5 on suse linux. Recently we have implemented dansguardian running on 8080 and squid on port 3128.

My rules file has entry Previous entry was ACCEPT loc:192.192.192.3 net REDIRECT loc 8080 tcp

Hi, I installed a network of five desktops in a small town hall, all running CentOS 5.4. The machines are publicly, and the mayor asked me to find some solution to effectively filter web content, as the kids' first reflex is to visit the interesting bits of the Internet first, from satanism to porn. One of the machines will be set up as a router anyway, since the public computer room

Hi all, Currently at work we use a commercial product called "Gnatbox", which, I believe, is a BSD derivative running on a floppy disk. They have a pretty UI and all, but I''d feel much safer/happier with a GNU/Linux box and Shorewall doing the same thing. In fact, I''m doing something very close to this at home using Openwrt and Shorewall on my WRT54G router, but I

Hi! I have setup a router with 3 NIC: inet->eth0->eth1-local_users ->eth2-DMZ_server I have also setup dhcp and DNS on the router. DHCP is server only for eth1 while on eth2 I have static IP address. So everything works except connecting local_users on eth1 to Samba shares on the server in DMZ by server name. Yes, I have it in my DNS records to point to it and with nslookup

Javier Fernández-Sanguino Peña has discovered an exploitable vulnerability in the way that Shorewall handles temporary files and directories. The vulnerability can allow a non-root user to cause arbitrary files on the system to be overwritten. LEAF Bering and Bering uClibc users are generally not at risk due to the fact that LEAF boxes do not typically allow logins by non-root users. For 2.0

Hi, I use CentOS as a firewall/proxy/webserver/fileserver in my small network. As the small-spec machine with CentOS is heavily loaded/used I can't afford downtime. 20 GB, pentium II with only 128 MB RAM. However I want to know the news on 4.5 is it due soon? Can I gain more by running CentOS 3.x range on such an old machine like mine? Will CentOS 5.0 mean you need a minimum of 512 RAM?
