New to pfSense

You’re right John, it isn’t working. I’m resetting the SG-3100 and starting over again.
-
John, let’s assume that I know nothing about setting pfSense router, and my goal is simple: configure an internet port out of 4 available ports on the 3100. My existing source is Comcast Xfinity modem.
Starting from a factory default 3100 unit, what steps should I take to fulfill my simple requirement: having an internet capable port in which I can plug in a switch and go from there?

It's pretty easy, if you have in fact reset the 3100 to factory defaults.
The SG-3100 has a WAN and 4 LAN switch ports (see image link).
https://www.netgate.com/assets/img/products/sg-3100-back.pngUse the wizard to do all of this. If you setup your WAN port properly (Static IP address or DHCP address from your Comcast modem), that should be good for that one. Then set your LAN switch ports up, using the default 192.168.1.0/24 address range. You can then plug in anything to the LAN ports, even a switch, like you're asking about. Leave the OPT1 port alone for now.
SG-3100 getting-started and setup instructions are here:
https://docs.netgate.com/pfsense/en/latest/solutions/sg-3100/getting-started.htmlIs there anything more complicated with your Comcast connection - VLAN stuff, PPPoE login stuff, TV/Phone/Security thingies, anything...? I don't think Comcast operates their modems with those kinds of settings, but I could be wrong.

Thanks Jeff for your help, but I have no luck. Not yet. No matter what or how I tried, I can’t see the internet from any port on the SG-3100. I just have no luck with pfSense.
-
And without you posting anything - its impossible to tell you what you are doing wrong...
So your lan has internet? And now you want to do what exactly with the switch ports
-
Hi John,
After configured as instructed in the SG-3100 manual, I have no internet from the only VLAN. The grey areas are firewall and DHCP server setup.
-
And again without you actually posting what you did there is no way for us to tell what your doing wrong.. Users say they did X all the time and come to find out they actually did Y..
You saying it doesn't work is not going to get anyone anywhere.
-
I followed the instructions printed on the SG-3100 PDF manual, pages 7 of 48 thru 12 of 48. At the end, I was told to create firewall rules, so I did. Basically, I created rules that pass ANY from ANY source to ANY destination. Then I was told to enable DHCP, and I did.
In general, I tried to follow exactly what the instructions said, and verified results after each step. Only thing missing is the internet from the newly configured port. That’s why I asked what steps YOU DID to get your results. Experts say doing this or that is easy but they skip the details.
-
And users say they followed instructions xyz... And they really did ABC!!
There is nothing to do other than create the vlan, put an IP on it and create the firewall rules.. That is all that is required.. So until you actually going to post up some pictures of what you actually did..
I showed you how vlans are setup on my 3100.. each port of the switch is on a different vlan. Each one has internet.. When you create a new network/vlan the outbound nat would auto create the outbound nats for you.
There is nothing to do but create the interface, and the firewall rules.. Can your client on vlan X ping the IP you put on vlan X?
What PDF manual? Are you talking about??
https://docs.netgate.com/pfsense/en/latest/solutions/sg-3100/I just went through that - and looks fine... What are you actually connecting to port 4?

I have a rather major problem that has only now been brought to my attention via the System Logs. Today, the firewall was reporting many requests on the WAN interface. At the time, I had no idea what the IP address was until I looked further. Turns out, my pfSense gui is available to connect on both my LAN address (10.10.10.10) as well as an address on the WAN DHCP Gateway (100.xx.xx.xx).
I have reconfigured the System settings and changed the port for https, disabled both the webConfigurator anti-lockout rule and Webgui redirect rule (I have created firewall rules to enable me to do this).
There is a VPN connection via OpenVPN however I have disabled all the settings and restarted pfSense and still I am able to access the webgui via the WAN DHCP Gateway address (100.xx.xx.xx).
I have not added any rules to the WAN firewall rules.
I must have overlooked a setting somewhere but cannot find it. Does any one know where else I can look to close this loop hole?
Edit: doing more research it seems the webgui listens on all interfaces. Is there a way to disable this? When I try and access the webgui via my phone on 4G/LTE it is blocked. How did these other external ip’s manage to find my webgui address on the WAN interface?
-
The default rules on the lan would yes allow you to access the gui on the wan address from the lan.. Since the default rules on the lan are any any.
If you want to block lan side access to your webgui on your wan IP, then you would need to specifically block this access.. This is where the "this firewall" built in alias comes in handy.
It will include ALL ips of the firewall..

This is entirely normal. Any interface address on pfSense is reachable from the LAN, unless specifically blocked. Try from elsewhere and see what happens. I bet you can't get in.
-
Yes you are correct. I made the mistake of checking the webgui via WAN ip on LAN and this did give me a shock!
How would these external IP’s have found the WAN IP address of the webgui when I didn’t even know what it was?
It would be good if in a future pfSense release they gave us the option of choosing which interface the webgui listens on. I would have thought it would be preferable to have the webgui invisible on the WAN side

When I try and access the webgui via my phone on 4G/LTE it is blockedSo what are these "external" ips that are accessing your gui? And how are you showing they are accessing your gui? A login attempt in the logs? Or your firewall listing a block?
-
When I tried via my phone on 4G/LTE I couldn’t even reach the webgui. Was shocked when I saw the logs and I tested the IP address seeing it was my webgui that opened!
-
Firewall was listing a block.
It listed as the interface being WAN, “from” being overseas IP (they came from America, Italy, Dubai and that was the ones that it could resolve. Used Shodan.io to resolve the others) and “to” being the WAN webgui address however on different ports (I have changed the https port from 443 to a much higher one)

So, it's performing as expected. As pfSense is a router, you can access any address on it. However, the firewall rules are applied to an interface, which is why you can get in from the LAN, where there are no rules blocking access, but can't from outside, as the rules are on the WAN interface. As I said, this is entirely normal.
The log entries show the firewall is doing it's job, when someone tried to get in from elsewhere. Your cell phone attempts should have also appeared in the log.

Well yeah there is a shitton of noise on the net.. Your firewall logging the noise is the default (log default blocks).. If you don't want to see the noise, turn off logging default block rule.
80/443/22/23/1433/3389 are going to see lots of noise..

I've managed to get Internet from a VLAN port on SG-3100. The speed on it however is much slower than that of from ISP. What can I do to get the speed the SG-3100 offers?
-
I have only recently set up DNS Resolver (prior to this I was using my ISP's DNS servers).
On one of my vlans is my FreeNAS server that has no access to the internet however I have made rules for it to be made available to the intranet as well as allowing DNS (via my ISP DNS on port 53) and Gmail (on port 587).
Is there a way to change the DNS rule to use the DNS Resolver? I tried changing the Destination to 127.0.0.1 however my test emails on my FreeNAS server failed.
Firewall rule is:
Protocol - IPv4 TCP/UDP
Source - FreeNAS address
Destination - 127.0.0.1
Port - 53 (DNS)
