Office communications server sin firewall RRS feed

  • Question

  • Que tal amigos como esta con un nueva inquietud, actualmente estoy investigando el office communications server 2007 le expongo mi escenario, tengo un server que es DC y exchange 2003, dns y emisor de certificados, otro con el OCS FE, 2 clientes XP y un EDGE server este ultimo fuera de mi dominio y  con una tarjeta interna y una externa, he seguido las guias de instalcion de microsoft asi como uno llamado "How to cheat at administering office communications server 2007", la situacion es que intermanente funciona bien lo que es la parte de IM con communicator y lo de conferencias con Live Meeting que es lo que a mi jefe le interesa, pero ya cuando entramos a trabajar al edge server me piden  que no ponga ningun firewall ya que unicamente se quiere ver el funcionamiento desde afuera de la red, en cuanto amis DNS yo solo cuento con una zona en mi PDC y ahi di de alta todos los host A y los SRV records que pide el manual pero no se si esto es correcto
    o si necesito hacer una configuracion extra ya que las guis no son lo suficientemente claras, y si es viable la conexion sin firewall

    de ante mano muchas gracias
