Hello all, Yesterday I noticed that my system was "leaking" traffic towards the 10/8 network, I have shorewall installed on multiple machines ranging from single interface devices to ones with 10+ interfaces. I tested all the boxes and they are showing the same behavior. All systems are CentOS 3.4, 2.4.21-27.0.2.ELsmp. Shorewall version: 2.2.1 For the host mentioned is a single

Hello all, Recently I migrated all telephony in my house to asterisk thanks to the Asterisk, QuadBRI which works wonderfully well. Some small tweaks to make but that's on the long list. On the short list is the ability to reliable send and receive SMS. For SMS I already built a script email2sms, but sometimes the SMS doesn't get send from some reason, the sms log then reports something

Hello Tom, I am not sure if you can help with this but I am at my wits end. If you hit this site and do a force refresh (ctrl + F5) the site will time out and lose connections. Do the same on port 443 and it does not time out??? The web site I am reffering to is www.tituswill.com I think the only problem is port 80. Do you have any idea how to diagnose this I have sent a dump of just

Bit of a shorewall newbie so if the answer is obvious please be gentle. We have been using version 1.4.2 for a while now and are very happy with how it performs, however we are looking to increase the resilience of our internet connection by providing a second internet feed. The idea being that should the primary connection fail shorewall will transparently (as far as users are concerned) switch

Most of the time i can find answers to my questions on the wiki, google, or searching the list now i am stuck . I have a small * box at my house running 1.0.9 stable and a devlite kit. Every thing is awesome VM, IVR, Echo canceling, and Meetme are all working great. But on Incoming caller id i need to add a 9 as a prefix to make it easier to return call from my cordless phone (cheap vtech

Hello all, Recently I purchased an QuadBRI card from junghanns.net after some playing around, reconfiguring dialplans etc with the exception of 1 thing everything seems to work: I seem to be unable to set the outbound callerid. The dutch telecom operator (KPN) provided me with 4 MSN's on 1 BRI interface. In the past years I'm more then used to setting the MSN without the leading 0, this

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

Hi there, I''m not sure if I can do this with shorewall, but any points on the right direction would be of great help... I need to have a LAN with access only enabled to certain set of computers. I was planning on having the dhcp server just give IPs to certain MAC addresses, but if a smart guy configures his computer manually with a valid IP for the LAN he can get access to the LAN

We have a webserver that is connected to three different networks. Due to our cabling, we have to run two of those networks over the same physical network. When connecting from OS X and Windows we are occasionally blocked because the client is sending to the wrong interface. Linux clients seem to have no problem at all. I have read the docs and understand that the problems exists because of

Cheers, This is fairly OT, but if this list doesn''t know, I''m under cross fire for a reason, yet to be found... ;) One of my firewalls gets hit by *lots* of packets from random source IPs and varying source ports. Measured by thumb, it''s more frequent than 1 per second -- thus rendering the log file almost useless [1]. Does anyone know, which apps use UDP port 8497

hi, it''d be very useful to add some kind of "log everything" option to shorewall. currently the logging is useful if you know what you would like to log. but if you don''t know than it''s a problem... another problem that currently it''s not possible to log the nat table. at least i can''t find any way (can''t add logging into masq and

Is it possible to define a file log such as for example /dev/tty2 in the configuration of shorewall. greetings.

Hi All, Our internal users need to connect to the bank to do internet banking. The bank requires that the client computers connect to ports 15000-15010. In Shorewall how do I do a masq for anyone trying to connect to these ports? Thanks Raymond

Hi gang, I''ve got a problem with shorewall, it keeps dropping packets when it should be DNATing them. I want all connections on a tcp port 4662 to be forwarded to a machine on my network (192.168.0.5) - the port is used for mldonkey (P2P app). It seems to be partially working - loads of packets are being DNAT''ed but some are not - I cant figure out why! The firewall

Hello, is it possible to configure Shorewall for different network environments? I am using it on a single Linux computer. When I am at home, I am using an internal IP address (192.168.0.X), and when I am using my cable modem, I get an internet IP assigned. I now want to be able to use Samba/Windows Filesharing when at home and to disable it when I am using my computer directly on the net.
