Multiple instance of proxy

Hi everyone, I have a question about proxy request with freeradius : is it possible to run multiple instance of proxy (not the same but the same daemon) which use different realm configuration. example : proxy 1 (port UDP 1812) : - realm @test.com - realm @test1.com proxy 2 (port UDP 1646) : - realm @test2.com - realm @test3.com Thanks in advance
