My dcgui-qt (chat/file-sharing program) doesn''t work and I''m pretty sure it''s my firewall settings. dcgui-qt is a direct connect (file sharing & chat) client. According to the FAQ here (http://dcplusplus.sourceforge.net/faq/faq.php) all I should need to do is: ------- #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL #

I must have something configured wrong somewhere. I''ve enabled proxy-arp on my shorewall 2.0.7 firewall. Works fine for what its supposed to do, I can see all the machines through it great. However, whenever its enabled, the network on the DMZ goes screwy. I''ve narrowed it down to this: when proxy arp is enabled for that interface, like such: echo 1 >

(anonymous post) I have a simple 2 interface firewall setup and all is good, almost. I am hosting virtual websites and DNS behind shorewall no problem. However I am trying to use SFTP via a different port number and have no luck even though Putty works well. Is there anything weird to sftp and shorewall? My lab uses a different firewall (firestarter) and it works OK. I am using; DNAT net

Believe me: Read the FAQ Checked over and over This might be toooooo stupid to be documented. Please bear with me. Any help ? Situation: single card standalone "firewall" (used like a "personal firewall"). Have sshd running on the FW.

I have had a web server listining sql-1433, www 80, ftp-21 using proxy arp with sub-netting in a three interface DMZ. All these ports are in the rules file as ACCEPT. With one exeception that 1433 allows a few host from the net. 21 and 80 allow all net to dmz connections. The policy is DMZ to net ACCEPT This has been working great for about a month or more until I rebooted the

Hi Guys, I need some help. I''ve been using shorewall for a while now and it''s been running beautifully, but I''m now experiencing some problems. It seems that connections are getting dropped much like the behavior described by the NEWNOTSYN=no option in the shorewall.conf file, but I have NEWNOTSYN=Yes in my file. The messages I see in my logs are things like:

I've been seeing this kind of crap now for some time, and only in the past couple of weeks did I realize I was using the Plus Kernel instead of the normal stock kernel. Could this have something to do with it? Messages also appear mentioning something about a PowerNow K-8, which I thought was something you'd see from an AMD processor, not a quad core intel 64 bit box. Any insight

I have what strikes me as an odd problem with shorewall. Let me describe my setup. My desktop (alfred) is connected to the network through an ADSL modem. I am running rp-pppoe, and this works perfectly. I have a small home network, with two LANs; an Ethernet LAN (including a machine running Windows XP), and a WiFi LAN, including the laptop (william) I am using now. All the computers except for

I've been getting LOTS of messages like the below in the daily log, and from all indications, it appears to all be related to the cpu; the machine is just over a year old, and was the old vortex.wa4phy;net server from the downtown co-lo site. Aside from huge log files, and lots of other fluff, numerous problems of other nature have started cropping up. Anyone have any suggestions as to

I''m attempting to setup Squid as shown on: http://shorewall.sourceforge.net/Shorewall_Squid_Usage.html#DMZ The firewall is a Bering 1.0 firewall running Shorewall 1.3.11, Red Hat 7.2 on the server in the DMZ.

Rowland, Thank you for all your help, I agree that this is not a Samba issue. Given rhat it works without the firewall. It' either a ufw or Windows 8.1 issue. Louis, Applied the rules you suggested to ufw exactly as written. No change. Still cannot connect with firewall enabled. Same error mesage as before "Cannot mount location ...". ufw log set to medium and copied below.

(Sorry, my previous post was sent in HTML format) I am having a hell of a time with shorewall... I have a Dlink DCM202 Cable modem with the Ethernet connected directly to eth0 on the linux box. Then I have a second nic on the linux box connected to a hub for the internal network. I am trying to allow traffic from the internet connect to my FTP and WEB servers on my Winbloze box on the lan.
