Hi:
I'm using 5.4 stable on an ALIX 2D13 with Compex WLM200NX
My internal network is 192.168.12.0/24
My ISP gives me 181.40.100.8 nm 255.255.255.0 gw 181.40.100.1 via DHCP
with reserved IP address. This is on vr0
No problems here.
I wanted to set up two internal networks
on vr1:
192.168.12.0/25
and on vr2:
192.168.12.128/25
athn0 is also supposed to be on 192.168.12.0/25
The intended /etc/hostname.athn0 is:
inet 192.168.12.2 255.255.255.128
/etc/hostname.vr0
dhcp
/etc/hostname.vr1
inet 192.168.12.1 255.255.255.128
/etc/hostname.vr2
inet 192.168.12.129 255.255.255.128
The weirdness is as follows:
according to ifconfig all interfaces are active
BUT
athn0 does not want to be on the same subnet with vr1
I cannot ping the internal IP 192.168.12.1
as long as athn0 is on 192.168.12.2 or any other address up to
192.168.12.126 that is in the subnet 192.168.12.128/25.
I have to change athn0 to the other subnet with
/etc/hostname.athn0
inet 192.168.12.130 255.255.255.128
In this case I can ping 192.168.12.1 and 192.168.12.130
(ping from inside the ALIX that is)
I pfctl -d to see if my PF rules have an influence, but no ...
You see that I followed the Book of PF 2nd edition to eventually being
able to set up a DMZ on vr2 while WLAN on athn0 and wired vr1 are on
the same subnet.
Is the weirdness in what I'm trying to do or is there some subtle bug?
Is there a reason that two different interfaces on the same system
must not be on the same subnet?
As a sidenote for the record: If one brings network interfaces down
and up and down and up and changes the hostnames in between eventually
the ALIX wants a hard reset - reboot is not enough; it will leave one
with all kinds of weird behaviour - mostly interfaces being active
according to ifconfig but not being pingable nor from inside nor
outside.
I hope someone can help.
Cheers
Eike
