I don't think this is a major problem to be honest. The issue I had back in January is that the behaviour changed with an upgrade to 10.1 from 8.something as the interaction with devd wasn't well known. I don't know how this can be dealt with unless we have a load of special-cases that log warnings when, for example, forwarding is enabled in sysctl.conf but there isn't a gateway_enable in rc.conf. That sounds like a messy solution to be honest.

Re: net.inet.ip.forwarding is mysteriously set to 0
Hi This happens when any interface is created if you've enabled forwarding with the sysctl and not using gateway_enable in rc.conf. It is easily fixed though.

Thanks, Nikos What is your setting for gateway_enable in /etc/rc.conf? Thanks Gary, I was not using anything in rc.conf. I was just using the sysctl in /etc/sysctl.conf. Setting gateway_enable to yes fixes the issue. I am kind of surprised.
