ASA-5505 Problem

Unanswered Question
Dec 27th, 2008

Hi! Fighting my ASA-5505 for a while now, still I can't get the inside users connected to the internet. My ADSL is an Routed-Subnet (Static IP, 4 IPS on a single line). When I connect a single PC directly to my modem port, the following IP settings are required: IP: 87.x.x.83, SubnetM:, Gatw: 87.x.x.81, DNS: & Works fine. Nevertheless, I can't get my network to work when the are connected trough the ASA-5505. Here's my setup. Can anyone please help?;

Hi Jon,

Is that a NAT rule? I'm working with GUI interface instead of CLI. I have CLI setup in the meantime, but don't know any commands yet.. :( Thanks!

Jon Marshall Sat, 12/27/2008 - 08:48

No it's not a NAT rule. The ASA needs to know how to send packets to the Internet. Without adding the route the ASA does not know where to send the packets.

So you need to add the route above to tell the ASA to send Internet packets to the 87.x.x.81 address.

Hi Jon, thanks for your quick response...As mentioned, I'm using the GUI version. Can you please explain where this line should be added? Thanks again!

(Maybe it's an idea to start a online chat of remote control session?)

Oke Jon, is it possible to post some instruction on how to set this up trough CLI. It looks like I can connect using the CLI, consule. Do I have to set it in config mode first? Please help! :(

Tim Roelands Sat, 12/27/2008 - 12:29

IT WORKS!!!! Thanks JON!

I entered CLI mode and added the rule mentioned earlier and...SUCCESS!!
