  • tunneling RPC

    Does anyone know how to tunnel DCOM traffic, ...I would like to have dcom sessions running between the DMZ and inside of a firewall without using port 135 and associated session ports. I don't want any rpc port limiting registry hacks.

    Thanks!

    Why not to setup IPSEC beetwen the Device in the DMZ and LAN ?

      Re: tunneling RPC

      Thanks for the reply, ...although I'm trying to shutdown open ports not just encrypt. I noticed Matrikon has a software product that proxy's OPC (DCOM), called OPC tunneling (but unfortunately it's specific to OPC) and uses a single port.

      Does anyone no if dcom over http might work? (I'm not sure I understand the mechanisms)

        this looks quite interesting about the mechanisms:

        I didn't read it completely but give it a try.

        But what are you trying to reach?
        What kind of firewall you're using?
