Here is a good place to start: https://help.ubnt.com/hc/en-us/articles/115002531728-EdgeRouter-Beginners-Guide-to-EdgeRouter.

No commands should be needed. Just update the ER-L firmware, then use the Wizard for nearly all cases.
-
ok i will try eth1 should be configured to lan or wan

Doesn't really matter. But just use the defaults.
-
connect to the ERL via console port or their defualt IP scheme.
upload the current firmware to it.
reboot
Run the setup wizard.
reboot.
eth0 should be your WAN and eth1 will be your LAN.
-
Ok how to a bridge the and create dhcp threw the router for the lan?

What is the bridge for? You are already routing, do you need a bridge additionally?
-
Under services you can set up the DHCP server.

This is done by the Wizard. if he followed instruction.
-
which one to pick wan+2lan .. or basic>
-
-
there are 5 wizards
-
Sorry, yes. Basic.
-
The others existed prior to the "Basic" existing.
-
OK just so I am following correctly.. eth0 is my wan..
layer3 ip///
and the eth1 is
my usable lan?

Define what you mean by Layer 3 IP, as you have it on a line by itself there so I have no idea what you are referencing.
But yes, your WAN is eth0, LAN is eth1. If you expand the view on LAN there you can setup the IP and subnet to match your existing LAN networking.
-
I HAVE WAN BLOCK....
LINK IP ADDRESS. X.X.X.240/30
LAYER 3 IP X.X.X.242
LAYER 3 SUBNET X.X.X 252THEN I HAVE LAN BLOCK
USABLE IP BLOCK X.X.X.X./27
USABBLE RANGE X.X.X.X-X.X.X.X.
USABLE SUBMET MASK X.X.X.224IF I CONFIGURE ETH0 AS WAN HOW DO I GET BACK INTO THE ROUTER , I WANT TO HAVE DHCP ON ETH1 10.0.0.1
-
Also, I think I see what you mean about bridging. It is in the basic wizard.
Do not do it.
Ever.
-
then how do i get dhcp on eth1 and get back into the router?
-
@mroth911 said in ER-3 -Comcast Fiber:

It should go there directly. not sure what you mean by "back in". DHCP isn't needed to access anything.

@mroth911 said in ER-3 -Comcast Fiber:
OK just so I am following correctly.. eth0 is my wan..
layer3 ip///
and the eth1 is
my usable lan?
If set by the wizard that way, yes.
-
ok so eth1.. that has the 192.168.1 .. what do i put there>

Is your entire LAN a public network? If not your LAN is a private range that you setup.

@scottalanmiller He has his own public IP block. noted as LAN from Comcast.
-
I have my own public block..

@mroth911 said in ER-3 -Comcast Fiber:
THEN I HAVE LAN BLOCK
USABLE IP BLOCK X.X.X.X./27
USABBLE RANGE X.X.X.X-X.X.X.X.
USABLE SUBMET MASK X.X.X.224Why do you have a LAN block? What is its purpose?

@mroth911 said in ER-3 -Comcast Fiber:
I have my own public block..
But why? Is there a purpose to it? You could just not use it.
-
IDK!
