route problem, I don't see where the problem is.

[Chip <chip_(_at_)_wiegand_(_dot_)_org>]

I just intalled OBSD2.9 last week, intending to use it as a firewall. I have 
two 3com nics, xl0 and xl1, with their corresponding files - hostname.xl0 and 
hostname.xl1. The xl0 is the inside network address 192.168.1.10 and 
hostname.xl1 is the outside static ip address provided by my isp - 
123.456.78.9. I have resolve.conf set up with the appropriate DNS numbers, 
ipnat.rules set up, ipf.rules are set up, and mygate has the gateway ip 
provided by my isp. I have the line net.inet.ip.forwarding=1 set in 
sysctl.conf. Everything looks correct according to the FAQ and various 
tutorials I've read. 
I run netstat -rn and get this:

When I ping anything on the internet I get 'no route to host' errors. I have 
tried several nics, all work in other pcs's and individually. I have set this 
box up with one nic as a client machine using my existing firewall and it 
pings the internet just fine, changed to the other nic, and it is fine, so 
both nics are good. 
Can anyone see what I am missing?

(My existing firewall is FreeBSD4.0 running ipfw/natd on a p133 with 40 megs 
ram. I want to replace it with OpenBSD2.9, ipf/ipnat on a AMD K6-2/350 with 
64 megs ram.)
