RE: firewall for MS RPC

Hi Tichomer,

ISA Server 2004 is a true firewall, and supports secure Exchange RPC publishing. Give it a try.

HTH,
Tom

Subject: [fw-wiz] firewall for MS RPC

Hi All

I'm looking for a solution for firewalling MS RPC protocol
A lot of firewalls can do app. inspection/ proxying of SUN RPC (old portmapper)
but except the MS ISA proxy none can do MS RPC.
I think it's because of "closed source" nature of MS RPC (nad MS at all :)

I have found closest to firewalling MS RPC is PIX with established command set,
(you can make ASA accept another connection from/to port/port range after connection to 135)
but I'd like to ask folks around here :

Is there a firewall/solution/workaround that does it better ?

there are workaround I'm aware of :
1. RPC over HTTP/HTTPS - requires ISS server
2. PPTP/L2TP tunnel with/without IPsec

with regards
