IS-IT--Management
I am sure it is something stupid I am overlooking, but been at it a full day now, and the numbers are all starting to look the same. Need to have this thing running in the next day or two, all and any help appreciated.
Here is the deal...have a Cisco 1721. Will be used to connect to a DSL modem. ISP uses a static IP, with the default gateway listed in the same subnet (more in a second). On the internal side, will be supporting an enterprise of about 50 users.
After initial configurations, the DHCP function is working, port forwarding from the outside to an internal webserver/ftp server is working. But I am unable to ping the default gateway supplied by the ISP and am unable to access the Internet from within the internal network.
Info provided by the ISP:
Availabe IPs:
156.X.X.186 to 156.X.X.190
Subnet Mask: 255.255.255.248
Default Gateway: 156.X.X.85
I only need to utilize one of the available IPs provided, in this case the 156.X.X.186
Below is my current configuration....what am I missing?
Thanks
Scott
