I have not tried any of this and do not know if it will work, but I think it will.

If your server has real IP addresses, not NATed in a firewall router, then you can create different echolink stanzas within echolink.conf and in each one put a different IP address. If you are NATed then you will have to know how to do policy routing in your professional router, like a Cisco router or maybe a routerboard.

The default if it is not configured is

ipaddr=0.0.0.0

But you would make it

[el0]

ipaddr=8.9.10.11

all the other commands

[el1]

ipaddr=8.9.10.12

all the other commands

[el2]

ipaddr=8.9.10.13

all the other commands

There are a couple of people on here that know if I have this correct or not, but I don't know. Let us know if this works, if you feel like experimenting.

Hi Loren,

I theory this would work, using one public address per Echolink instance.
In the server world this type of setup is basically known as multi-homing.

However, I don't think the AllStar Echolink driver was written where the
developer expected anyone to attempt to perform multi-homing. So, assuming
this is true (i.e.: Echolink driver not multi-home aware), the situation
is probably much more complicated....I won't delve into the gory technical
details of what's needed for multi-homing, but, very simplistically
speaking, the application must "remember" what IP address an inbound
request came from and then answer back using that same source address.

Minimally, I expect some significant NAT (network address translation)
trickery with a Linux firewall will be required to pull this off. I'm
working feverishly on other aspects of this project right now, but, I'll
put this on my list of things to look at, if no one else beats me to it.

And, I agree, this would be useful capability. I've got a couple repeaters
right now running on the same control PC and separate echolink
connectivity to each would be useful.
