[App_rpt-users] Bind echolink channel driver to 2 nodes?

I just enabled a private node on my CentOS install. The main public node #41477 is currently bound to the echolink channel driver. How do I also concurrently bind it to the other private node #1477 as well as 41477? The entry in the echolink.conf file is: astnode=41477 can one do astnode=41477,1477 ;or some such kludge? Any Help appreciated. -KM6HK
