hi all !
me and my friend are fighting now for days upon a certain (complex)
at first i thought this is impossible but now i know nothing about it.
i'm no linux guru, but i try to :-)
here's my problem:
i have a local subnet 192.168.0.0/24
connected to world 0/0
everythings allright so far, but know the problems arise:
i have 3 public fix ip-addresses like 22.214.171.124, lets assume i have ips
from .3 to .5
my world comes to fw from eth1
my local is eth0
my designated public ip computer is at eth2
now my router plugged before firewall is located in _the same_ subnet as i
have my public addresses, that means my router (reachable through eth1) has
ip 126.96.36.199 (same subnet as my public ips).
this consequently means that i have 2 _same_ subnets on 2 _different_ ifs
(eth1 & eth2).
first question: in general, is it possible to have 2 same subnets on 2
different ifaces ?
i tried this. it works only partially, and i'm not sure wether the problem
is routing or masquing...
if i configure both eth1 and eth2 as same subnets, i can reach both subnets
from fw-machine.. so far so good,
my masquing is only for eth0 (yet)...
now i want that eth2 (my given public ips) are forwarded through fw, so that
i can ping the world from 188.8.131.52, which is plugged to fw via eth2....
this is the breaking point anyway. no matter what i try ___i cant ping world
from my fix public ip-machine___
is this network topology possible to configure anyway ???
whats the goal of such a config ? -> i just want a webserver running on
184.108.40.206 secured by fw-machine has ip 220.127.116.11 (eth2) plugged to world
via router (18.104.22.168) on eth1 and a subnet 192.168.0.0/24 on eth0...
i know it's getting a bit complex, but it's a challange for you (and me),
isn't it ? :-)
btw: i use suse6.3 and ipchains
if you can help me, you guru outside spending whole weekends configuring
networks, __plz__ help me...
