Q:

Networking setup with Cisco ASA 5505

I have a problem configuring a Cisco ASA 5505 in that client workstations from our inside LAN can't access the internet through the ASA. I'm trying to implement it within a business network behind a Cisco WAG320N router:
ISP >> WAG320N >> ASA5505 >> Switch >> LAN Network.
I've configured the ASA like this:
vLan2 - outside - 
ip address xx.xxx.xxx.23 (this is our static IP) net mask 255.255.255.0
security-level 0.

vLan1 - inside  - 
ip address 192.168.1.1 net mask 255.255.255.0
security-level 100.

dhcpd address 192.168.1.5-192.168.1.120 inside

global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0

route outside 0.0.0.0 0.0.0.0 81.xx.xx.xx 1 (ISP gateway).

I'm guessing that I have to set my router (WAG320N) into bridge mode, or do a static NAT on the router to point to the ASA; but I'm not sure.
Any help would be greatly appreciated as I'm not even sure that my ASA config is correct.

A:

As I understand your setup the ASA should have the public IP address and should function as your router ?
If you do so you don't need the WAG320N.
you can just directly attach the ISP connection to your ASA I suppose,
Unless your connection is an ADSL / SERIAL connection and your asa doesn't have these ports.
you should setup the WAG320N and use a /30 subnet between your ASA and WAG320N.
