  • Noob Qn: RDP & RWW - Confgiuring Optus Cable Router with ASA 5505

    Hi guys,

    I've put in place a Cisco ASA 5505 at home to start learning a bit about them, I'm now trying to setup RDP & RWW access to my internal server.

    The layout is this:
    pub internet (say 8.8.8.8 ) -> Optus Router (Cisco DPQ3925-X) 192.168.0.1 -> 192.168.0.99 Out Cisco -> 192.168.1.1 Int Cisco -> Svr 192.168.1.2

    On the Optus DPQ3925-X
    - I've gone into: Applications & Gaming - Port Range Forwarding
    - Added port forwards for 43, 3389, 3389 on TCP to 192.168.0.99


    I'm using ADSM to make the changes.
    I've configured the security policy Access Rules like the below picture.


    I've read articles that suggest I need to configure NAT, however I only have 1 public IP address so I'm not sure if this is necessary? I've followed their steps and have this now set up in NAT:


    When I run the packet tracer I get the following result:


    Assistance would be appreciated - thanks all!

    Cheers!

    Hmm, slow forum.
    Can anyone at least confirm I've set up my IP addressing correctly?

    Can anyone suggest more active Cisco forums? I started with Petri because it's always been so helpful in the other forums

      You're basically trying to double-nat I think ?

      You're natting 3389 etc on the DPQ to 3389 on the ASA.
      The ASA then needs to either NAT, or Route, to an internal device.




      the Cable LANIF address is 192.168.0.1 and WANIF is 8.8.8.8
      the ASA WANIF is 192.168.0.99 and LANIF is 192.168.1.1
      The internal server is 192.168.1.2

      so firstly, you need to NAT from the Cable device to the ASA - make sure this is working, I'm sure you could debug the WANIF on the ASA and see if the packets are hitting it (Even if they get denied)

      actually.. looking over it again - it seems correct..
      your traffic analysis looks like it's dropping on the NAT rule

      try enabling PAT as well ? (Port addr translation in your image)
      see if that helps (I'm guessing..)
