I feel like I'm missing something painfully obvious, but I just can't
see it.
I have someone who just got ADSL connected and I talked them into
letting
me setup an obsd firewall. The adsl modem that the ISP sent only does
bridging (Netgear DM111) and although I got it all working, it feels
like an
awkward hack that will bite me in the ass later on if I don't do it
properly now.
If I set my external interface on the obsd box to dhcp, the adsl modem
gives it
the correct static IP (103.113.194.79 mask 255.255.255.0) but no
default
gateway gets set.
If I logon to the adsl modems web interface, it gives me the following
details:
IP: 103.113.194.79
Gateway: 103.17.101.67
If I set these manually on the obsd box, it doesn't work as the default
gateway
isn't in my subnet.
Ie, IP: 103.113.194.79
Subnet 255.255.255.0
Gateway 103.17.101.67
The way that I did get it to work was manually setting the subnet mask
to 255.0.0.0. Now the default gateway is within my subnet and so it gets
used and at the moment, everything seems to be working ok, but this
feels like a dirty hack that will bite me later on.
Is there a better way to do this???
I can't see how a dmesg will help, but just in case.
