Hi Friends, I am running Centos 5 64-bit on a Dell sever. I am trying to configure iptables for smtp traffic for which I need some help/guidance.

Hi, We have a 256 kbits/s (kilobits per second) link to the internet. it is a router running Linux that belongs to our ISP. They have given us 8 internet ips. (i.e- subnet is 255.255.255.248). one has been given to this router. I have given another internet ip to the firewall running CentOS 4.5. iptables is running on it. And also, I have installed iproute2 pkg as well. pls see below for

Try to SNAT the incoming conection too, then your server see only the 200.x.x.x IP for the incoming calls. You have DNAT for redirections, add a postrouting SNAT. I supose that you are DNATing in PREROUTING and you will add a rule (only for example) for SNAT the incoming calls from 200.x.x.x router: iptables -t nat -A POSTROUTING -d <internal server ip> -j MASQUERADE Perhaps

Hello, I have 2 ISP uplinks (zones: inet1 and inet2), each with a fixed IP on the outside and a routed subnet (/25 and /26) on the inside.

The segments are completely isolated from eachother: hosts in zone "lan1" connect only to "inet1" and hosts in zone "lan2" only connect

Hi I set-up a gre tunnel between two linux boxes.

The problem is if i log in

An very interesting test did yesterday that, LAN1 and LAN2 setup an tinc VPN which is quite simple(the physical link between tinc nodes are quite stable/fast), and no any application traffic to go through the tinc. Later, I setup smokeping which LAN1 initial 20 ping to LAN2 on a per-minute basis, but as you saw from the below picture, it had packet drop. But if I perform a constantly ping from
