Hi Matthew,

I know that is a nasty hack, but the problems are the "fancy vendors" that
has big and famous appliance completely out of standards. my approach about
this, It replaces the process of my web-portal to send a COA in my default
port 3799 and after a little fix[1] on FreeRadius I can pass/proxy the
packet to the other port (In this case, the appliance listening to acct,coa
and auth in 1812)

It will be possible to override the destination port. This solves my whole
saga! :)
