Hello,

I've checked around on here already, but couldn't get this to work.  I need to get remote desktop forwarded through a cisco asa5505 with the software asdm version 5.2 (3) and asa version 7.2 (3), these versions were in the about section of the software.

Thanks.

Open the 3389 port in ASA firewall using Access-list. U can use the following comand.
access-list  (access-list no:) extended permit tcp any any eq 3389

and then place it in the appropriate interface (Incase already access-lists are configured in the appropriate interface , Just use that access-list no: wer i have written access-list no: in brackets.

pls make  neccessary changes according to ur requirement.

Good luck.

I agree with lentinsun. If there is no access-list that block your traffic (see logs) don't forget to check your NAT statement if nat-control is enabled.

If you can post your current config we can give you all the exact commands. It is very difficult to do using the ASDM, but actually very simple using the command line. You can even use the ASDM's Command Line Tool, multiline command and we can give you the commands to copy/paste, submit, done.

Should I just install microsoft hyperterminal and connect to it that way?  I'm pretty sure it'll be the default config, as the asdm looked pretty empty.

If ur firewall is connected to network..better u use Putty telnet(http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html). It is a free tool.

access-list  (access-list no:) extended permit tcp any any eq 3389 (create the access-list)
access-list  (access-list no:) permit ip any any
now access the interface wer u want to put the access-list
access-group (access-list no:) in interface outside  (placing the access-list in suitable interface)


pls use access-list-number between 101 to 199 as this is an extended access-list.

The asdm is fine. You don't have to worry about connecting console cable/hyperterm or putty..

If it is default config, edit/copy/paste this into the Tools| Command line tool | Multiline command box
Replace <IP of RDP Client> with ip address of the PC you want to RDP to.

access-list outside_access_in permit tcp any interface outside eq 3389
static (inside,outside) tcp interface 3389 <IP of RDP Client> 3389 netmask 255.255.255.255
access-group outside_access_in in interface outside

the only thing I've ever done one on of these devices is reset the password, using a cisco support doc.  The reason I mention this is because I'm not a command line cisco guy.  Do I need the commands in () as well?  If someone could please just lay out exactly what needs to be inputted I would greatly appreciate it.

Thanks.

Firewall# configure terminal
firewall(config)#access-list 110 extended permit tcp any any eq 3389
firewall(config)#access-list 110 permit ip any any
firewall(config)#interface (u should find out ur outbound interface and put it after interface)
firewall(config-if)access-group 110 in interface outside

U can find out ur interfaces using show interface command like below

firewall#show interface

Good luck dude....hope this will help u...other wise u can give a try to asdm. Revert back if u have any doubts...
