Help with port forwarding on Cisco ASA5505

[viperman]

Hello,

i have the task of getting port forwarding working on this cisco router(ASA5505, 256 MB RAM, CPU Geode 500 MHz Internal ATA Compact Flash,128MB). I am a cisco novice. What I'm trying to do is have ports 3389 and 25 forwarded from the wan side(69.88.205.110) to the lan server(192.168.20.1).

Here's the config:

ASA Version 7.2(2)

I didn't do this and it obviously doesn't work but like I said, I'm not a cisco guy. Any help would be greatly appreciated.

Hi Viperman
Your's configuration is OK and it's must work. The problem is on 192.168.20.1 machine, check on default gateway, firewall. Maybe try connect from other computer in your 192.168.20.0 LAN to this services (25,3389).

I'll check when I'm on-site but I'm almost sure those services work internally. How to I enabled logging(and which logging) to see from an ssh session if the connection is going through or not. Thanks.
