I'll chime in here as well.  While it would be nice to have the second or X
number of nics, I think we are close to having our network routing issues
licked.  I would not expect this to be connected to the internet directly
and am perfectly happy running it behind one or more firewalls.  
 
I understand the complexities of introducing an additional nic into an
environment designed for a single nic.  I have not gotten into a multi box
setup, but plan on digging into that further in the near future.  If
failover/redundancy works on a single nic great!  I am used to boxes have a
nic for heartbeat and at least one other in a HA environment.  This goes
beyond what I was trying to accomplish in my previous emails, but I do agree
with Tony.
 
I was just about to look into rsync for the backups but FTP might work since
it is all internal to us.
 
BTW - spix is up and I am able to access it.  Routing did the trick.  Thank
you all for helping out with this! 
 
Andrew

I'm not a developer but find sipXecs better than most packages to
maintaining a stable and supportable environment for our sip infrastructure
needs. These are my comments, mine alone, and do not reflect those of any
other party. Please take them in a friendly and supportive manner.

Depends on how security conscious you are (IMO). 


With "Network Admin" hat on: multi-homing servers that are configured to sit
on both public and private networks is as common as dust under a sofa. 


sipx is not designed to be a firewall. A lot of work goes into the
sipxconfig gui, and a lot of developer time would have to go into writing
iptables management within sipxconfig to remain consistent with the goal of
the project. multihoming changes the overall scope of that in some way.

sipx is being designed to offer high availablility features, with proxy and
other functions able to take over the functions of a failed or disconnected
system. Multihoming would certainly make that less tolerant in some ways. It
is not meant to run multiple NIC's, favoring an enterprise facing firewall
instead of "being a firewall also". 

It has its own backup routine and can backup via ftp, there are also methods
to backup via smb (cifs). The media functions within sipx are latency
sensitive, therefore no development work has gone into SAN or NAS, or
supporting multiple nic's. Be aware the media server is being replaced in
4.2, and work towards supporting other features in 5.0 which have not been
announced yet.


The roadmap will have more. 

http://sipx-wiki.calivia.com/index.php/Detailed_Roadmap_sipXecs_IP_PBX
 

If you have a NAS or SAN setup, you've probably got multiple interfaces. If
you pull backups across your network, you've probably got multiple
interfaces. Out of the 30 or so servers we currently have deployed, maybe
two of them have a single interface and they're on the "need to upgrade"
list.

Wasn't this issue supposed to get fixed for 3.10?

 Thanks for the input.  Maybe I will end up making the suggestion for future
releases to allow multiple IPs.  :)

   the issue is that six will bind the ips to the proxy. there should
   onlt be one. you should not have 2 ip's on the box, period.

       We are workign with Juniper EX4200 switches which are pretty

       think we can add the route right in the switches.

The only real question I saw here was "wasn't this supposed to be addressed
in 3.10?  

No: http://track.sipfoundry.org/browse/XX-4818

states that is was not completely fixed. It is also referenced here:

http://track.sipfoundry.org/browse/XX-6146

When you look at http://track.sipfoundry.org/browse/XX-4818 please note that
it does not have a fix version or schedule yet.

While I myself understand how you feel about this, many others have been
able to use an independent firewall or appliance and run sipx internally
with "probably better" security results. Also, while you are telling
everyone on here how you really feel, perhaps you can take a deep breath and
post some queries to both the users  and developers lists asking "why" or
"when". 

While the function to multihome (that IS what firewalls, vlans, routers,
vpns, etc ARE for) is not present at the moment in sipxecs, I don't think it
makes it LESS or a replacement candidate for another system. Every
environment is different, with different needs. 

I don't find TRIXBOX or any * based system high on my list. That's my
preference, and I'm free to choose, as you are. At the end of the day, we
may have different needs and use different tools to fulfill those needs. At
least noon is forcing you to use something you don't want to use.

Good luck!
