hi...
i have a situation where i have a system with two connections, one wireless,
one eth connetion. i can currently connect with the wireless ath0 to my
network/internet/etc...
however, when i activate the eth0 at the same time, i can't access the
network via ath0. as far as i can tell, i need to implement ip masquerade to
have eth0 map, to ath0...
my test ip addresses are:
ath0 - 192.168.1.33
eth0 - 192.168.2.33
any thoughts/comments/pointers...
You don't need IP masquerading, unless this system's going to be a
gateway to the Internet for other computers.
You don't need IP masquerading if some other device is already doing it.
The other device does need enough routes to access everything connecting
through it, but in the usual case (you only have one subnet) that's how
it's working. In your case, I assume you're using a "hardware" router
and it's IP address is 192.168.1.1 or 192.168.1.254 (these are defaults
for some brands). If it can be configured to route traffic to
192.168.2.33 via 192.168.1.33, then you don't need IP masquerading, you
just need to configure the route.
You do need both interfaces active at the same time, and network manager
cannot do that at present, I've just engaged in a lengthy discussion
about that either on this list, or on -test.
I don't know whether network manager can be configured to do one network
and not the other.
In addition to configuring both network interfaces to be active at the
same time, you also need to enable forwarding in /etc/sysctl.conf
Here's script I run for myself, for a similar task. It doesn't show
everything, and it won't suit you without some work.
[root@localhost ~]# cat bin/startrelay
#!/bin/bash
ifdown eth0
ifconfig eth0 172.17.0.1
route add -net 192.168.9.0 gw 172.17.0.19 netmask 255.255.255.0 eth0
service dhcpd restart
[root@localhost ~]#
ath0 in this system provides access to the Internet via a Linux system
function as an Internet gateway. It's configured via system-network-config.
"ifdown eth0" takes down the configuration established by
system-config-network for eth0, I don't want this configuration to be
standard.
