Hi Boris,
Does anybody know if there is a convenient utility to configure
iptables on a CentOS 5.4 or 5.3 machine to do port forwarding?
And if not, where and how does one put the requisite commands?
I'm using iptables just as command. For information about service and
very useful examples lo

Hi listmates,
Happy Thanksgiving!
Does anybody know if there is a convenient utility to configure
iptables on a CentOS 5.4 or 5.3 machine to do port forwarding? And if
not, where and how does one put the requisite commands?
Thanks.

I'm having some port forwarding issues issues with iptables.
We are using iptables as a firewall with 2 nics and on ip alias.
I'm trying to port forward on the alias ip
eth0 = 65.x.x.1
eth0:1 = 65.x.x.2
eth1 = 192.168.x.x

No, I only have one mailserver with one domain I'm managing with about
30 users. I think I have the routing working properly now, as well as
the acl's.
I put some route statements on eth2 for the private network and that
seems to have resolved issues.
I do have an authentication issue with ldap,

Well after running into more issues with the connections, we wound up
putting a third network card in the main server. They thought this a
better solution rather than forwarding the packets.
So now my issue is I have 3 nics.
eth0 - 10.10.10.1/255.255.255.0
eth1 - x.x.x.x/255.255.255.252 - Public

Hi,
To implement either 1) or 3) you need to mix iptables and iproute2 to
route packages matching specific criteria.
The "Linux Advanced Routing & Traffic Control HOWTO" has a specific
section on this, and an example very similar to yours (although they
show how to route outgoing e-mail traffic a

Yes, the packet must return to the original source in the Internet
with the y.y.y.y source IP.
Your machine with IP x.x.x.x probably has a default gateway in eth0

I think port forwarding is working fine, it's the routing of
the traffic back to the source that is not because linux doesn't
handle multiple default gateways very well out of the box. Look
into multi homed routi
I'm having trouble getting port forwarding working on my one box.

I have 2 servers on these connections.

Can someone tell me what, and where the file that contains the port
forwarding info is on a standard install? I had a server fail, I have
mounted the drive and need to get this info back.
Thanks.
