I am having a problem getting a connection using a Cisco ASA 5505 and a SMC Business Gateway.
I have called Comcast and they set it up in Bypass mode and I configure the outside to one of our static IP's anbd Gateway, and no I didn't use our gateways public address. I must be missing something because from the ASA I am not able to ping the gateway or DNS servers. If anyone has suggestions, ideas, links I am all ears as I am at a loss as to why I can't get this to work.
Any info is appricated, thanks!
Hello khowitt and welcome,
I would first make sure your ASA WAN configuration ia infact contains the following:
a.) correct routable Static IP address
b.) correct gateway Static IP address
c.) correct sub-net mask Static IP address
d.) primary 188.8.131.52 and secondary 184.108.40.206 DNS addresses
If you are using your ASA DHCP Server, then having your SMC DHCP Server disabled with avoid any conflicts.
Hope this helps you out.
Now that you say that, I was using ASDM to configure the port 0 as WAN or VLAN2, and I don't recall seeing anywhere for a default gateway, just IP and Subnet. Wonder if it is as something simple as a command to add the default gateway. I do know when I was testing, I setup my laptop with the correct settings and I was able to get out. So I just need to figure out how to modify the configuration for port 0.
All networkiing device that can be setup for a static IP must always use a.) routable static IP address b.) gateway static IP address c.) subnet mask static IP address, and good practice to always add the primary and secondary DNS addresses.
a. + b. + c. are always minimally required - FYI

Without a default gateway, your router won't know how to get out to the wider internet.
Here's a link to the manual
Not sure how you are on the CLI, but it appears the command would be:
route <interface_name> 0.0.0.0 0.0.0.0 <comcast_gateway_IP> tunneled
Don't quote me on that though, never used this router.
