Insert SG-1100 between existing cable modem and router
-
Having problems making this work.
I followed the instructions to start up the SG-1100. I then went into the setup wizard and walked through it.
With a laptop plugged into the SG's LAN port, I can browse the internet so that tells me that the LAN port is getting out. The SG has a LAN IP of 192.168.1.1.
When I unhook the cable from the laptop and plug in the cable going to my wifi router (Ubiquity AirRouter), I get no connectivity downstream (even after restarting the router numerous times).
If I open a browser (on a PC on the LAN) and browse to 192.168.1.1, I get the AirRouter's configuration screen rather than the SG's setup screen. So there is an address conflict. And of course I can ping that address from the LAN.
I went back into the SG and set it's address to 192.168.1.2, thinking that would solve the problem, but no luck. From a LAN pc, I cannot browse to 192.168.1.2. If I ping it, I get a reply from 192.168.1.200 that the destination is unreachable. Not sure where that is coming from.
I did add 2 firewall rules to pass all TCP and UDP traffic; those rules sit below the built-in rules.
I am not sure exactly what to try next. Appreciate any help! Thanks.

There are several ways you could address this. For instance, you could give your laptop a static IP address of 192.168.1.2, 255.255.255.0 mask, no gateway and then connect your LAN port directly to the AP and then try to hit its web interface at 192.168.1.1.
Or you could unplug the AP and then get to pfSense WebGUI and change its LAN IP address and mask to 192.168.2.1, /16 mask. Also change your mask to 255.255.0.0. Then plug in the AP and hit its web interface.
Once you get to its interface, see if you can change its mode from the static 192.168.1.1 to DHCP. If not, then change it to 192.168.1.2. Turn off its DHCP server if one is enabled. You just want it to act as a bridge to LAN, and let pfSense handle giving out addreses. Make sure you have the DHCP server running on LAN and configured or your wifi devices won't get an address.
Once you have changed it, go back and restore your pfSense LAN settings to their original 192.168.1.1/24.

Good progress but not quite there.
I have my AP set up as a Bridge. SG gives each device (both wired and wireless) IP addresses via DHCP. I can ping any other device from any device, on the LAN. But nothing gets out to the internet (or back).
In the SG my Dashboard shows all green up arrows for everything, except OPT which I haven't done anything with.
In the Firewall, I added 4 rules: tcp and udp "pass" for both ip4 and ip6. They are green-checked. They are below the built-in rfc 1918 and reserved rules.
I suspect I have a something blocking traffic but not sure what.
-
Success! I realized I needed to create Firewall rules to allow tcp and udp on the LAN side.
Appreciate all your help #KOM! Very grateful.

No if its the default lan it would be any any rule out of the box.. You only need to create rules on new interfaces/vlans OPTX, the out of the box lan defaults to any any rule.
In the Firewall, I added 4 rules: tcp and udp "pass" for both ip4 and ip6.
You didn't create rules on your WAN did you?
-
Please post screens of your WAN, LAN and OPT1 rules so we can check them out for you.
-
Ok.
Wan:
Lan:
I realize this probably isn't "firewalling" much of anything right now. My plan was to get everything on my network operating then research how to set up the best rules and lock the device down.
-
Rules are evaluated top-down, first match wins. No other rules are processed after a hit.
On your WAN, get rid of those last four allow rules.
On your LAN, also get rid of those last 4 rules. The second rule is already passing all IP4 traffic. Those other rules you added aren't really doing anything. If you're not using IP6 then go to System - Advanced - Networking and disable IP6 there.
-
Ok done. And, everything still works. Thanks folks for the help.

-
If you do disable IP6, don't forget to go back to your LAN rules and delete the IP6 ones you manually added.
-
There you go - much better ;)
See no need to have created any rules..
-
Thank you both.
So with the "factory" rules (only) in place, am I better protected than without the SG, or not really until I start creating more specific rules?
-
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?
