Monninger" Subject: netmask question/probem Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I connect to my ISP via a DSL line. It's really just a standard ethernet connection. They use dynamic IP addressing so I run the wide dhcp client. I also run natd to connect my home LAN to the internet. Everything has worked fine for several months until Friday when my ISP changed the netmask sent from the dhcp server to 255.255.255.255. My system (2.2.5R) quickly stopped talking to the internet. I get No route to host messages and when I try to add a route I get Network is unreachable. To make it work I manually change the netmask to 255.255.255.0, add the route, and it's fine...until the dhcp client renews and the mask gets set back. OK...I have a work-around...I can hack the dhcp client to ignore the netmask or use the ISC client. Here's the question...should this netmask work? They claim it works fine on Windoze. The goal is to force all traffic on the dsl subnet to go thru the router so that dsl users can send traffic to each other (I don't care about that but others do, apparently). Is there something in the FBSD IP stack that chokes on it or is it something in my configuration? Any help will be greatly appreciated.
