I edited my original post for the wrapping problem and, as a result of
Christian Baer response, I tried the default settings, so now I have the
original (empty) /etc/dhclient.conf. Same result.
I had a working minimal FreeBSD system until I put it behind a wireless
router. Since then my network is not accessible anymore when I boot BSD.
On the same desktop I have a Gentoo Linux system which works just fine,
even if I didn't touch any of it's configuration files after I installed
the router.
The router is a ZyXEL P-335U wired to a cable modem. The desktop is
plugged into a LAN port. A laptop connected by wireless has no problems.
The router gets it's IP from the ISP and acts as a firewall and a DHCP
server to my network: it serves a pool of 32 addresses starting at
192.168.1.33. Its own address is 192.168.1.1. The IP Subnet Mask is
255.255.255.0.
The configuration files for FreeBSD are shown below.
The output of ifconfig and netstat are also shown for BSD and Linux.
What confuses me is the fact that having the same router settings, when I
boot in Linux the network is usable, while in BSD it's not: I can't even
ping 192.168.1.1, while the same ping in Linux works.
I read the handbook and various other BSD information sources on the web
and I could not solve this issue.
My question is: which config files do I have to edit and what settings
should I use ?
Thanks,
