Comcast metro e and ASA 5512-x configuration

mikeprennie — Fri, 21 Feb 2020 13:18:52 GMT

I am trying to get the basic configuration set up for my new ASA 5512-x

I have the Comcast fiber --> copper fed from the ciena switch port 1 into the ASA Eth(0)

I have a laptop plugged into Mgmt Port

I have a laptop with DHCP plugged into Eth(1)

I set up the following config in ASDM

Eth(0) Outside

IP Address: Comcast Layer 3 IP: 50.BBB.BBB.BBB
Subnet Mask: Comcast Layer 3 Subnet Mask: 255.CCC.CCC.CCC
Security: 0

Eth(1) Inside

IP Address: 192.168.100.1
Mask: 255.255.255.0
Security: 0

Static Route

Interface: Outside
Network: any4
IP Address: 0.0.0.0
Net Mask: 0.0.0.0

Gateway IP: Comcast Gateway: 50.AAA.AAA.AAA

Is this all I need for a beginning basic internet connection to the laptop in Eth(1)

Any advice is greatly appreciated.

You will want to set your inside security level to 100 and your outside to 0.

Hi mikeprennie, Did you resolved that??

I am having the same problem, following is my Comcast Info:

IP Information:
– /30 between Comcast end and the customers layer 3 device and a /27   ( 30 Usable IP's )

P2P                      /30= 50.iii.x.yy
Subnet                      = 255.255.255.252
Comcast SUR            = 50.iii.x.aa     gateway
MyCompany IP link         = 50.iii.x.ab     to customer provided router

                             /27= 50.jjj.cc.d
Subnet                      = 255.255.255.224
Thirty usable IPs starting with 50.jjj.cc.1, 2, 3 …

will you say that your 50.BBB.BBB.BBB = 50.jjj.cc.1 (I chose that)

and 50.AAA.AAA.AAA = 50.iii.x.aa

Please let me know.
