  • Cisco ASA 5520

    plz consider the following scenario



    Inside network Outside network


    PC
    192.168.1.1
    -------------(192.168.1.250)--- ASA Firewall---- (62.220.20.1)----------------------- INTERNET
    Server
    192.168.1.100



    • Nating is done correctly
    • ASA inside interface (192.168.1.250) trust level 100

    ASA outside interface (62.220.20.1) trust level 0

    I have enabled remote desktop connection on the Server and locally I am able to connect from PC using the ip 192.168.1.100

    I have also mapped a public IP i.e 62.220.20.30 to 192.168.1.100 with port 3389.(both nating and accesslist is there)
    From outside when I use remote desktop connection with ip 62.220.20.30, I can connect successfully no problem

    The problem is that I want to use rdp using 62.220.20.30 to connect to the server while I am working locally (inside network). i.e from PC.

    Before when we were using Juniper firewall I was able to connect using 62.22.20.30 locally.

    The point is that while I am using 62.220.20.30 with rdp to connect to my local server (192.168.1.100) it shud go to internet thru ASA and then come back to the inside network thru ASA again (like a loop). With juniper it was working. I think that some conf need to be done in ASA.
    I have searched a lot but still I am not able to find the solution.

    The PIX didn't support traffic going out and back in the same interface so I would imagine the ASA doesn't too although there are some other things involved.

    Personally thought, why do you have to use IP addresses? Why not setup DNS records so you can connect to "rdpserver.test.com" internally and externally. The users don't know the difference and there is no load on the firewall.
