Hello, I'm trying to set up port forwarding in IPTABLES and so far it's working great from the internet, but when I attempt from my internal LAN using the External IP address, it fails. EXTIF="eth0" INTIF="eth1" EXTIP="xxx.xxx.xxx.xxx" INTNET="192.168.1.0/24" INTIP="192.168.1.1" PORTFWIP="192.168.1.13" >From the internet,

Hi, I know that this is a known problem but I don''t know the solution. I have a linux server with iptables, kernel 2.4.17. Now in logs appear (Debian): kern.log: Mar 1 23:12:55 cpie kernel: ip_conntrack: table full, dropping packet. Mar 1 23:13:56 cpie last message repeated 10 times Mar 1 23:13:59 cpie last message repeated 3 times Mar 1 23:14:10 cpie kernel: NET: 1 messages

Hi there. I have followed some documents found here and there, but do not have already success implementing a script using iptables and iproute. What I need is to send all traffic trough an ADSL line, but mail trough an expensive and slow DS0. The mail server lies on the PC acting also as firewall. I include the script. When using that I get some error messages (I found that the flush command

Currently I have shorewal 2.2 installed om my debian 2.6.8 kernel. The firewall machine can access the internet via a ethernet modem fine. The firewall can ping the local network. The local network can ping the firewall server, see the samba files. Howeven teh local network cannot access the internet through the firewall Any suggestions?

i just got a ''ip_conntrack: table full, dropping packet'' because a p2p-application ran amok. i''ve killed the process but /proc/net/ip_conntrack still got more than 7000 (now stale) entries of 8184 max. since the table is now after ~70 minutes down to 6995 entries, i wonder if i can flush this table manually. the entries in there look like tcp 6 155674

Hi all, I''m new to shorewall and have been struggling with several problems for several days now. Most of them are solved, but one still persists. The firewall is running on my server under Debian Sarge (Kernel 2.6) I''ve got three network interfaces: ppp0 (DSL Internet) eth1 (lan) ath0 (wlan) eth1 and ath0 are bridged together to br0. The problem is, that Samba (also running

i''ve read your http://lartc.org/howto/lartc.rpdb.multiple-links.html article as well as Advanced IP Routing (esp. chapter 10.4) and still unable to make this thing work. am i that helpless? :) is there anyone to guide me through the multiple ISP setup? into details. i got 2 dsl connections from different ISPs (A and B), both connections use PPPoE, both got assigned with dynamic IPs

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 hope this isn''t a dupe. Evolution crashed on my last send and I see nothing in my logs that leads me to believe the mail made it out before the crash ] Well, it probably is working. I''m probably just misunderstanding something. Given routing rules that look like this: 0: from all lookup local 10000: from all fwmark 0x40 lookup CGCO 10001: from all fwmark 0x80

(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.

I wonder if someone can tell me what these ''unknown'' remarks mean in my status file. They are only in the last portion of the file and are listed below. If they mean nothing, I will rest easy. But if not it means I need to fix something. Your thoughts would be appreciated. ---------------- udp 17 92 src=24.224.173.220 dst=24.222.0.75 sport=1027 dport=53 src=24.222.0.75

I'm replacing an ancient Solaris 'ipf' firewall/router with a brand new CentOS 6.3 system. In the olden days, I successfully used the attached iptables script (as /etc/rc.local) on Red Hat 5.x systems, but this doesn't seem to be quite working on the new system. Specifically, while it seems to be routing ok, you cannot connect to anything on the inside net (e.g., with ssh or

I have been encountering a rather hard to debug problem for the last couple of months: * Calls are setup fine. * After a couple of minutes, two way audio becomes one-way and the remote or local party drops out of the call.

Hi, I got a problem with iproute and shorewall but I don''t know where the real problem is yet, perhaps someone can shed any light on this one. What we currently do is route all traffic coming from a specific host through our second isp''s nat router. This is done via SNAT on our own router. /etc/shorewall/masq: eth2 $INTERNALHOSTA 192.168.0.142 We now
