Re: offlist was [ Re: [LARTC] about Linux router ]

2002-11-21 Thread Rimas
Hi again,

Ok I will try to explain more.


Wireless radio modem my default gateway for router (which I want to get
installed)
Of couse I can connect radio modem straight to my FW and thats it.
But in this case I can connect only one FW (I have two one is production and
second one is backup/testing)
I will draw a small pcture what I want.
(I speak only about real Internet IP's.)

Wireless radio modem
--
| Ip 1.1.1.1   |
--
 |
--
| Linux router| what I want to install (with two ethernet cards)
--
 |
-  
| Hub/switch|--- | FW 1 |-- Local network (SMTP, POP, WEB, FTP servers and
etc)
- -
 |
   -
   | FW 2  |
   -
|
Local network

How you see from my draw I would like to make a router with Linux box (I
have an old PC for that
and no neds to buy some Cisco or another router.

Re: [LARTC] about Linux router

2002-11-20 Thread Debreczeni Peter
iptables , ip route is simple job for a linux
and tcpdump/ethereal for debug
but i don`t understand how you build your network
2 ip for your fw and 1 for a linux box , why?
configure a linux to filter packet , but you know ... :)

I don't want to a new Cisco or whoever router I would like to do it on Linux
box.
I prefer to use RedHat 7.3 for that and what I have to install on that Linux
box (iptables, ip route and etc ) ?
Two IP's will be for my FW's and one for router (like default getaway for my
FW's).

Thank you in advance

[LARTC] about Linux router

2002-11-20 Thread Remus
Hi folks,

I got a new one Internet connection (Wireless) and to have more then one
external IP I need a router.
I don't want to a new Cisco or whoever router I would like to do it on Linux
box.
I prefer to use RedHat 7.3 for that and what I have to install on that Linux
box (iptables, ip route and etc ) ?
Two IP's will be for my FW's and one for router (like default getaway for my
FW's).

Thank you in advance

Remus
