ASA 5505 (8.4) Subnetting issues


I have an ASA 5505 and I would like to create two subnets on it, but I'm having trouble getting some resources on the second subnet exposed to the outside world.

The first subnet is located at the 192.168.1.x range, and the second is at the 192.168.50.x range.  I'm able to expose the Outlook Web Access server on the 192.168.1.x range just fine, I can't seem to expose the web server or VPN on the 192.168.50.x range.  I've tried fiddling with NAT and Access-Lists but I'm obviously missing is my current config:

Result of the command: "show config"

ASA 5505 (8.4) Subnetting issues

Hi Adam,

I'm not seeing where you created the VLAN Interface for your the 192.168.50.x subnet.  Nor am I seeing a route to the 192.168.50.x subnet, so I'm assuming you simply forgot to create it.

Your Firewall currently doesn't know how to get to the 192.168.50.x subnet, it either needs the interface created or a route statement added. 

Hope this helps.

Re: ASA 5505 (8.4) Subnetting issues

In addition to Eddie's reply, your VLAN 1 has a /16 mask. Is that what you wanted?

That's a bit unusual (although it's the topic on the thread) and you have the http statement for ASDM management referring to the network as a /24.
