Re: [44net] How to make traffic coming in on the tunnel interface get answered from that interface?

Yes, my solution assumes that 44.1.1.1 is assigned to the tunnel and that all services run locally. So let's get this also up and running :-) But I need some data: do you have a single IP assigned, or a subnet? In other words, is there a possibility to to assign one ampr address to the tunnel (it is ok even if it is not registered in the dns) or do you need to use a single IP address only on the JNOS? -----Original Message----- From: 44net-bounces+marius=yo2loj.ro(a)hamradio.ucsd.edu [mailto:44net-bounces+marius=yo2loj.ro@hamradio.ucsd.edu] On Behalf Of Michael E Fox - N6MEF Sent: Saturday, December 27, 2014 22:20 To: 'AMPRNet working group' Subject: Re: [44net] How to make traffic coming in on the tunnel interface get answered from that interface? (Please trim inclusions from previous messages) _______________________________________________ Mario, I guess I'm still missing something. In your suggestion below, 44.1.1.1 is the address assigned to the AMPRnet tunnel on the linux box. But once the inbound packet arrives there, it must still traverse another tunnel, tun0, to JNOS (in my case). Then JNOS responds. But the source address is JNOS's address. Linux is just acting as a multi-interface router. So an "ip rule" based on a linux interface as the "from" address doesn't apply. Or, does your solution assume that linux is also NAT'ing the traffic, converting the source address of the outbound back from the JNOS address to the 44.1.1.1 address, after which the ip rule gets applied. (I'm not sure of the processing order. I'd have to get out my iptables book!) Thanks, Michael N6MEF
