I currently have a DSL modem which is configured with static routing and connects to the switch where I have a number of device, till there everything is working fine, I have bought an asa 5510 so I can have remote sites connecting with it through VPNs. I want to configure the asa 5510 to receive WAN Connectivity from the DSL Modem which is Cisco EPC3925, This modem is currently configured with static IP routing. What I have tried to do is to set it as a bridge mode only and configured the following configurations on my ASA:  

ASA5510(config)# interface Ethernet0/0
ASA5510(config-if)# nameif outside
ASA5510(config-if)# security-level 0
ASA5510(config-if)# ip address 213.165.177.76 255.255.255.224 (My Static IP address provided from the ISP)
ASA5510(config-if)# no shut


ASA5510(config)# interface Ethernet0/1
ASA5510(config-if)# nameif inside
ASA5510(config-if)# security-level 100
ASA5510(config-if)# ip address 192.168.0.1 255.255.255.0
ASA5510(config-if)# no shut


ASA5510(config)# global (outside) 1 interface
ASA5510(config)# nat (inside) 1 0.0.0.0 0.0.0.0

ASA5510(config)# route outside 0.0.0.0 0.0.0.0 213.165.177.65 1 (ISP Default Gateway)

ASA5510(config)# dhcpd dns 212.56.128.132 (ISP DNS Server)
ASA5510(config)# dhcpd address 192.168.0.10-192.168.0.200 inside
ASA5510(config)# dhcpd enable inside

I have tried this but it haven't worked, I have another DNS Server I haven't used which is 212.56.128.132, if this can help. I have set the IP address of the internal switch to static  which is 192.168.0.205. Sorry I am quiet new to this field.

Thanks in advance for all your help.

What version is the ASA running?

Your config would be good for versions lower than 8.3

I don't configure firewalls to use external DNS, I always use an internal DNS server.

If you are not able to traceroute over the ASA to the Internet, you might need to specifically allow ICMP, or it could be an issue with your DSL modem in bridge mode.

The ICMP Worked but I have to add also the dns lookup server and enter specifically the dns. Thanks for all your help :)
