default route to different subnet

[jason thompson_1]

I have a net route that points to a gateway on the same subnet as the server. Can I add a default route that points to a gateway on a different subnet? I have tried editing /etc/rc.config.d/netconf and route add default xxx.xxx.xxx.xxx 1.

I know you can do a route add command and edit the files so it's there for good. But usually I just use the:
#set_parms addl_netwrk

Since I use this, I don't have the right route add syntax.

A gateway is used to direct trafiic on different subnet than the host itself .
So I think its not possible to do that . But I am not sure as I have never tried doing it .

Hi,

You can't define a router in a subnet where your computer doesn't have an adapter.

Sorry

[Thomas Bianco]

the thing about default gateways: they're default. "in the event we don't know where the packet goes, send it over there and let that router figure it out". if the default gateway is on another subnet, to whom would you send message destined for the default gateway?

you can define routes to "far" subnets, but in general, it's best not to and let the gateway (router) do it's job.

if this is the case, you would set the gateway to whatever router was actually connected to that subnet*, rather then localhost or blank


*more accuratly: you would set the gateway to whichever router on the local subnet is closest to the far subnet
