Adding second ethernet card

[Zathros]

I have a redhat linux 5.2 machine set up as a firewall/mailserver. It was configured by someone else so I'm not sure as to what all is setup on the machine. I need to add a second ethernet card since we are converting from a dialup line to a dsl. Are there any gotchas I need to look out for? I've read most of the "manual" that came with the op system and it seems straight forward enough.

I'll also need to know how to turn off the automatic dialup when the machine is booted.

I don't think x is installed on the box so I probably need to use other config programs than the gui.

My main system is SCO unix, so I'm familiar with a lot of Unix commands and so forth, Just need the ins and outs of doing this with Linux.

Thanks!

My guess would be that if the dialup happens on startup, it would be in the rc.local (or a similar) startup script, which on my RedHat system should be located in /etc/rc.d/

I would just remove the reference to the dial-up in this script.

Hope this helps

A couple of thoughts. I run an old Dell 486 as a firewall between my local lan and an @home DSL. It's Slackware based and I haven't really looked at the setup in a while - it just keeps humming.

In my case the firewall rules are ipchains based. In your case your firewall rules will likely be based on ipfwadm. In either case I would think would have to modify your "rules" to use the DSL IP address rather than the one assigned by the dial-in service. If both are DHCP based should be no big deal. The how-to's on these set-up's are pretty good.

Obviously, you will have to configure the second ethernet card (address, ...)!

Good Luck,

Well now the netopia r3200 idsl router is in place and the confusion begins!

I have no idea how the rules are based. I didn't configure the mailserver.

If my webhosting company that set up the mailserver and the analog line will let me keep the static Ip address, I think it will be easy. Just add another card with another static Ip from the idsl company and it should work. I have the mx record on our domain set to send all email to the ip supplied by the web guys.

At least, I think it will....
