Insert SG-1100 between existing cable modem and router
-
Yes. Default rules allow all traffic out from LAN, and block all unsolicited traffic in to WAN.
-
depends - with the default rules nothing has been forwarded from wan/internet to your behind pfsense router that is for sure.
Not sure why you want or think you need another router behind pfsense.. If you want wireless - then just use an AP.
edit
What is this exactly "Ubiquiti wife router." Do you mean an AP like an AC-Pro or -Lite? What is the model number of this device? you have from unifi?An intelligent man is sometimes forced to be drunk to spend time with his fools

@johnpoz. It is an AirRouter. I have it set up in bridge mode. Although most of my gear is hard-cabled, I have a couple of devices I can only get to via wifi.
-
@johnpoz Courierdog here and I have a similar requirement.
My ISP provides the Fibre ONT (Modem) to their ISP Router.
The ISP Router also provides the IP TV and the ISP provided Home Security System
From the ISP Router I feed a Bitdefender Box 2 (WiFi Router)
The Netgate SG-1100 does not have WiFi
I would like to configure the SG-1100 so all the ethernet LAN connections pass through the SG-1100 which then connects to the Home Network Switch.
The ISP Router provide the Internet connection
The Bitdefender Box 2 provides the monitored WiFi Access Point
The Netgate SG-1100 provides the Firewall for the Home Ethernet network
I have in the past used a Router with Tomato Firmware whereI now want to place the Netgate SG-1100
I configured the Tomato Router as a static IP addressed Bridge using one address within the range of the Bitdefender Box 2 DHCP range of addresses.
I am unsure if the Netgate SG-1100 can be configured this way or would it have to be placed in front of the Access Point which would have to be configured as the Bridge.
Thanks in advance -
It can be configured as a transparent firewall like that but doing so requires bridging VLANs.
It's almost always better to avoid bridging if you can.
An Access Point would normally be a layer 2 device anyway, no need to bridge anything or already internally bridged.
I'm unclear where the USP router fits in here. Potentially you have 3 routers with 3 levels of NAT. Really you want 1.

We have no option on the ISP Router That Must stay in place.
However, I have revised my thoughts.
ISP Router -> Netgate SG-1100 Firewall - ASUS RT N66U (WiFi AP) -> Home Network Switch
This requires me to reassign the SG-1100 LAN IP
Currently the SG-1100 Put me directly to the Dashboard this is not what the User Guide states.
At this point I am lost.
I may be Somewhat of a newbie but the SG-1100 is not following the Documentation.

At this point I am lost.Huh?? When you setup the sg1100, yeah would be able to access the web gui, on the default 192.168.1.1 IP - unless you changed it?
Directly to the dashboard of what - how or where does it say in the documentation anything different?

I assume you mean you're not seeing the setup wizard?
That can happen if it was previously launched and then escaped but you can run it again at any time fro System > Setup Wizard.

@johnpoz
Problem is the ISP uses the 192.168.1.1 LAN IP address so I have to change it.
The guide says go to Advanced - Option 2When I login, I am sent directly to the dashboard
The setup wizard does not appear.
Even if I set up using and empty WAN port and connect my Mac directly to the LAN port, Login takes me directly to the Dashboard.
Very strange. -

You can set the IP via here option 2
What is the page in the docs your looking at exactly - can you post the url your looking at?
Here for example

@johnpoz let me start over.
my ISP (Telus) provides my Internet/TV/Home Security
I want to leave all of that on one network and using the Netgate SG-1100 to provide my Home Internet Network.
The ISP uses the Standard 192.168.1.1 IP LAN Settings
First I have to change the LAN of the SG-1100 to something different
However the WAN side of the Netgate SG-1100 will come from the ISP Provided Router.
Currently I have managed to LAN configuration of the SG-1100 but the WAN side of the SG-1100 is not connecting to the ISP Router.
Where / How in the configurations settings do I enable the Netgate SG-1100 to accept the Internet connection as provided by the ISP Router.
I hope this makes sense.
I mentioned this to a friend who uses pfsense and he did say I have to enable something on the WAN side to accept the feed from the ISP Router. -

No you don't... You can for sure use 192.168.1/24 on your wan - many users do, just a double nat.
He might be thinking about the default block rfc1918 rule, but the dhcp hidden rules that allow pfsense to be a dhcp client would allow it to get a rfc1918 address.
Change your lan of pfsense to be say 192.168.2 and you would be fine.
-
@johnpoz my limited understanding is Double NAT is not a good thing.
changing the LAN side to a secondary LAN assignment minimizes the issue or so I have been told.
Assigning as an example the pfsense LAN to the 192.168.2.1 or anything except the ISP DHCP assignment minimizes the Double NAT issue.
My current issue is the WAN side will not connect to the ISP Router and thus the internet.
I can connect the to the pfsense Device from the LAN, fine but the device is not connecting on the WAN side.
Hence the question of a setting for the WAN Side to enable it to communicate with the ISP Router -
@courierdog said in Insert SG-1100 between existing cable modem and router:
anything except the ISP DHCP assignment minimizes the Double NAT issue.
What? Your still double natted..
Change the lan of pfsense to be something different than its wan.. And will be fine - double nat is not optimal no... But works just fine... Many Many people do it, seen triple even quad nat, etc.
It is not an optimal choice but shouldn't be a problem.
@courierdog said in Insert SG-1100 between existing cable modem and router:
but the device is not connecting on the WAN side
What is not connecting to what exactly? Does pfsense get an IP address from your isp device its connecting too or not?
If you want something on your pfsense "wan" to talk to something on pfsense lan. And want the wan device to start the conversation. Then yes you would have to turn off the block rfc1918 rule that is default on the wan. AND you would have to setup a port forward for whatever it is your wanting to do.
If something on pfsense lan wants to start a conversation to something on pfsense wan - that would not be an issue.
-
OK Now you are way over my head.
Like I was attempting to say, I can communicate with the SG-1100 via the LAN port.
The WAN is not seeing the internet at all.
Is there any means to return to factory settings and I can start over. Just in case I have done something inadvertently.
I followed the Quick Start Guide but when I connected the WAN port to the SG-1100 it failed to connect to the ISP Router and thus the internet.
The first strange thing that happened when I plugged in the power was when I logged in from the first time,
The login was per the Quick Start Guide.
From then on everything has been different than the Guide.
First, Login -> Directly to Dashboard.
The Quick Start Guide does not explain what to do when you arrive at the Dashboard.
I am sure if the guide covered this situation I would not be sitting here scratching my head and not knowing what I did or how to proceed. -
You can reset to defaults from Diag > Factory Defaults in the GUI or using menu option 4 at the console.
The setup wizard runs one time only automatically. If you escape it at any point it won't run again. But you can manually run it anytime from System > Setup Wizard.
Do you even see link LEDs on the ports when you connect the WAN?

@stephenw10 Thank You Ever So Much.
This was the Most Helpful Response I have received to date.I would suggest this NOTE be placed in the beginning of User Setup Guide.
It would explain what is happening, to many people especially those who become frustrated and give upEven My friend who uses pfsense did not explain this to me.
Before this note I was about to pack up the Netgate SG-1100 in the box and return it as defective.
I may have to run through this procedure a few times to verify for my self exactly what is happening and time each segment noting the LED Status with each step.
Please be patient with an old Man (80) who is still finding new things every day.

No worries. Keep asking questions, that's what I'm here for.

@stephenw10 Have No Worries, I have many more questions.
The SG-1100 has a significant lag time for the reboot process.
Even after using the System -> Diagnostics -> Factory Defaults
Login to the SG-1100 takes a considerable time.
So I am not convinced, at least at this point, that the device default setting are correct.
There is still no internet connection passing through the SG-1100
I would have thought this would be a Default Setting.
I have a Zoom Meeting starting at 0900 I will get back to this after the meeting.
Thanks for your patience, I am sure the device will work, however some how there is an incorrect setting preventing the (Automatic) connection to the internet.
Dave -
It should indeed provide internet to a LAN side client by default when WAN is connected to something providing DHCP.
Reasons it may not include:
Subnet conflict. The WAN is using the same subnet the LAN does by default.
No DHCO server on the WAN connection.
No link on WAN so it cannot connect.Yes, the boot time is significantly slower when there is no valid WAN connected. A number of things have to timeout during the process.
