[nos-bbs] JNOS networking

[Jim Smith]

Oog. Using iptables to forward JNOS traffic from the Ethernet port to the
JNOS process is like using sledgehammers to kill flies. It works and is
stable, but IMO not worth the effort. 

 

Somewhere in the archives of this list (I think) is a post from myself on
how I do it. Basically I create a tunnel (using the tun device), then shell
out to create an ARP entry that links the linux end of the tunnel to the MAC
address of the Ethernet interface. This causes any traffic on the wire for
the tunnel leading to the JNOS process to be picked up by the Ethernet
interface and passed to the tunnel.

 

I find my way to be a darn sight easier to configure than fiddling with
iptables. One day I may formally write it up and submit it to <insert site
here> so that others can benefit.

 

Cheers!

Yes Mike, but it is an OS setting, not JNOS.

it's been a while I played with it but checkout iptables, it should be able
to listen for ip frames for jnos and forward them on.

There are several ways to implement FORWARD documented by Maiko, in the
archives of this list, and on the JNOS wiki [if it is now up].  The one I
prefer is to include "echo 1 > /proc/..." in a script that also sets various
permissions initiated by JNOS start-up that you included in your post.  But
you need to pick what feels best to yourself.
