Hi,
I got myself an APU2E2 and am trying to set it up as a router. To learn
how to do this I'm mostly following the "Building a Router" FAQ [1]. For
simplicity's sake I'm only using em0 and athn0. This is my setup:
.-----------.
.----------. .------------. | APU2 | ))) client1
| Internet | <--> | ISP-Router | <--> | em0 athn0 | ))) client2
`----------' `------------' `-----------'
I want the clients, that are connected to athn0 to be able to access the
internet, but it doesn't work. What works is this:
1. I can connect my laptop to athn0, ping the IP of athn0 and even the
IP of em0. Pinging the ISP-Router doesn't work.
2. If I connect my laptop to the ISP-Router, I can ping em0.
3. When I am on the router (via ssh or COM-Port) I can ping em0, athn0
the ISP-Router, openbsd.org, ...
So what I can't figure out is why I can't ping the ISP-Router and
servers on the internet, when I'm connected to athn0. My APU2 setup is:
$ sysctl net.inet.ip.forwarding
net.inet.ip.forwarding=1
$ cat /etc/mygate
# This is the ISP-Router:
192.168.178.1
$ cat /etc/hostname.em0
inet 192.168.178.2 255.255.255.0 192.168.178.255
up
$ cat /etc/hostname.athn0
media autoselect mode 11n mediaopt hostap chan 36
nwid <mynwid> wpakey <mypw>
inet 192.168.3.1 255.255.255.0
$ cat /etc/pf.conf
pass in log (all)
$ cat /etc/rc.conf.local
dhcpd_flags=athn0
$ cat /etc/dhcpd.conf
subnet 192.168.3.0 netmask 255.255.255.0 {
option routers 192.168.3.1;
option domain-name-servers 192.168.178.1;
range 192.168.3.20 192.168.3.100;
}
I'm an absolute noob when it comes to network configuration, so the
problem is probably something really stupid, but I can't figure it out.
I'll appreciate any hint!
