Hi Chuck and Everyone,<br>
<br>
This morning I decided to give this a quick test and it partially works.<br>
But, as I feared the chan_echolink driver doesn't seem to be fully<br>
multi-homed.<br>
<br>
Chuck, as you suggested, the ipaddr=a.b.c.d parameter does allow a user<br>
configured address, different from the main AllStar address, that echolink<br>
binds to. But, the IP address that the channel driver advertises to the<br>
echolink node-list database is still the base address of the network<br>
device, not the address specified by the ipaddr=a.b.c.d parameter,<br>
unfortunately. (Probably some quick driver code hacks could fix this...)<br>
<br>
So, for now, multiple echolink instances bound to different IP addresses<br>
via the ipaddr=a.b.c.d parameter won't work as expected.<br>
<br>
HOWEVER, I also tried the port=xxxx parameter to allow a user specified<br>
UDP port other than the default ports (5188, 5189). This DOES seem to<br>
work, at least from the channel driver standpoint. So, there is hope for<br>
using NAT to accomplish this goal, as I initially suspected. I'll try some<br>
NAT rules and test this further as soon as I get a chance--unless someone<br>
else beats me to it!<br>
<br>
My config file looked like:<br>
<br>
[el0]<br>
port=6622<br>
all the other parameters....<br>
<br>
[el1]<br>
port=6632<br>
all the other parameters....<br>
<br>
Then, hopefully, Linux NAT rules should be able to accomplish the rest!<br>
<br>
<br>
