Looks like it, for a manually added route (commonly named
"adding a _static_ route").

-static just sets the RTF_STATIC flag, but in src/sbin/route/route.c,
newroute() sets RTF_STATIC anyway (and has done since 1994) unless you
deliberately use -nostatic, so -static is a noop when you add a static
route. If you adjust a route added by some other method, you might
need it though.
newroute(int argc, char **argv)
{
char *cmd, *dest = "", *gateway = "", *error;
int ishost = 0, ret = 0, attempts, oerrno, flags = RTF_STATIC;

I recall having to use the -static option to make the routes stick. Maybe this was made the default recently or maybe the -static option does something more than mark the route as S? Lars Hansson

You might want to use the -static flag with that, otherwise the route will dissapear forever (or at least until you reboot) if, for example, you lose carrier on the interface. --- Lars Hansson

Now i would like machines on my LAN to be routed towards 172.18.254.1. Seems to me your default gateway should be 172.18.254.1 because that's what your OpenBSD box is plugged in to.

Re: Newbie routing question
Charles, You can actually insert the route command in your hostname.if (replace 'if' with the interface you are using). you would insert the following line at the end of the file to add the router after the interface comes up. There may be a better way to do this, but this will work. !/sbin/route add 10.82/15 172.18.254.1 charles Collin wrote: > Hi, > > I'm really new to OpenBSD. > I recently installed version 3.9 and am trying to set it up as a > router/NAT. > > I have 4 interfaces on this box: > 1 for man LAN > 1 for my DMZ > 1 for a my client's private network reachable via a Cisco router > linked to a T1. > 1 for Inet (i got 8 public addresses, among which one for my box > interface and another for a Cisco router connected to internet via > ADSL, let's say my IP is I.N.E.T2 and the router's is I.N.E.T1) > > The IP address of the LAN interface on the Cisco router is > 172.18.254.1 and i cannot change it (i don't own it, it is my client's). > The private network's address is 10.82/15 > > I set up /etc/mygate with the default gateway I.N.E.T1. > Now i would like machines on my LAN to be routed towards 172.18.254.1. > I can do that with a: > > route add 10.82/15 172.18.254.1 > > The only problem is when i reboot the OpenBSD box, this route disappears! > > I can't figure out how to make new routes persistent, though i've been > googleing quite a lot. > > Is there any file in /etc that gets read by the system at boot time > that configures additional routes like /etc/mygateway ? > > Thx a lot > > Cheers

You can add !route add 10.82/15 172.18.254.1 to the relevant /etc/hostname.if file, and the route will be added when the network interface comes up.
