-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, this might seem like a classical problem but I''ve trouble getting this working correctly: # ifconfig ### output stripped down: eth0 Link encap:Ethernet HWaddr 00:50:FC:2B:EB:1B inet addr:192.168.5.220 Bcast:192.168.5.255 Mask:255.255.255.0 eth1 Link encap:Ethernet HWaddr 00:02:44:60:EC:58 inet

Dear all, Has anyone experienced this whilst running DRBD over eth1 between two CentOS 5.7 servers? eth1 is a private IP address, unroutable. eth0 is the public address. CentOS will reply sometimes once every 3 days or every 14mins~ saying "My public IP is on eth1" to arp requests when it's not, it's eth0. This freezes traffic and causes issues. We've looked at arp*

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

Hello. My name is Riku. Currently, I use Dovecot as a proxy for another SMTP server. However, this seems to cause the IP address of the "received" header to be that of the proxy server. Is it possible to change this so that the IP address of the sender is entered? The version of Dovecot is "2.3.8 (9df20d2db)". Sorry for the incomprehensible explanation. Thank you. Best

Dear all, Dear support and users: Sorry to trouble you! I configure the shorewall firewall to forward ftp and ssh port to another server, but failed. Can you help me check?

This one is really throwing me. Thanks in advance for any advice. I''m working on a 4 port firewall system. It is running heartbeat+drbd.

Hello all, I have an annoying networking issue. The value of arp_filter is getting changed. /proc/sys/net/ipv4/conf/eth0/arp_filter 1 I specifically set it to 0 via /sbin/ifup-local. The hosts in question are setup to test some network gear, and they all have 1 "management" interface and 1 or more through put interface. Any ideas on how to keep this value from changing? -- Milton

Hy shorewall users :)) I have the following config in my shorewall: DNAT net:200.137.193.2 loc:192.168.0.55 udp 135,445 - 200.137.193.38 DNAT net:200.137.193.2 loc:192.168.0.55 udp 137:139 - 200.137.193.38 DNAT net:200.137.193.2 loc:192.168.0.55 tcp 135,139,445 - 200.137.193.38 The IP

I''m trying to setup some DNAT and the packets seem to be disappearing after the PREROUTING step. The packets are coming in eth2 (both LOG targets in iptables and tcpdump confirm this). They are then DNATed to an IP that should cause them to go out eth3. However I never see them go out that interface. I have tried putting LOG rules into the FORWARD chain with no success. I''m

Hello everybody. I have a problem with my firewall rules on my Slackware Linux box 9.0 (kernel 2.4.20-xfs). This system is configured with 3 NIC (one for the router, one for the dmz, and the other for the private net). I have written a firewall (iptables) that is processing packet based also on the incoming interface. This firewall is connected in a not good environment where all the NIC (and the

Hi ! Recently i switched my internet provider, to get more speed but another braindead setup regarding public ip addresses. I now have 4 PPTP Tunnel available, of which i''m using one as the gateway ip doing masquerading to other machines in my local lan, excluding three other machines, which i would like to use 1:1 nat to get them a direct access to one of the pptp tunnels.

Hi, I've been trying to get a couple of routers up after h/w failure. The border router is an OpenBSD firewall running NAT between the Internet and a DMZ like subnet, and in that a Linux antivirus server is running NAT to the LAN. When the client does a DNS query it reaches to the f/w where dns is running and is returned into the A/V server but never hits the 0.254 interface. (Shown by

Hello All, I am trying to implement OpenVPN on Fedora core Linux 3 with the latest pathces installed. This server is used only as firewall/internet gateway/proxy/VPN server, with kernel 2.6.1-1.27.FC3 and kernel 2.6.1-1.27.FC3 SMP It has two NIC''s eth0 (10.0.0.150) connected to ADSL, eth1 (192.168.3.12) connected to the local network. I use shorewall 2.4 on this machine. I like to test

I''m very new to shorewall. My setup is IP Gateway (CentOS 4 + Shorewall) with 3 NIC cards. Shorewall works great on the firewall machine. Bind also works (local net machines get IPs fine). Under firestarter, all works great. With shorewall, the loc machines can not route past the firewall. They can connect to the firewall, but not past it. Exactly what information should I post to get
