How to assign Domain Controller to VLAN Systems

[slkamath]

@johnpoz
Thank you very much.

How to put default deny rule (please find the pic below is it correct)?

Again did some changes.

Quality-VLAN

Gear Symbol is for Upload & Download limit set so it shows that symbol. In LAN there are nearly 10 IP's. All VLAN has to access those IP's (Shared Folder, Network Printer, Backup, Domain Controller, Tally).

LAN

Can you suggest any book or something so that i will get some knowledge to make it correct.

I suggest reading this chapter from the pfSense book:
https://www.netgate.com/docs/pfsense/book/firewall/firewall-fundamentals.html

Thank you Stephen.

Did you post the wrong pic - your qual ne has the block rfc1918 and bogon again..

Your lan rules everything below your any any is just pointless!! Not sure why this is so difficult to understand..

Imagine a source IP:PORT and DESTIP:PORT and protocol - now run through your rules top to bottom.

You have an ANY ANY rule - any protocol and source any dest.. So when would that rule not trigger and get to the safe_IP rule??

When would something not trigger that any any rule and fall through to your block rules? Your any any allows ANY, so
clearly ports 80 and 443 are part of ANY..

If you don't want IPs getting to 80/443 then those rules go ABOVE your any any rule.. Those will then be blocked and other ports like say 123 would not trigger those rules and be allowed through the any any rule.

Thank you Very Much

Sorry for the delay.

I made few changes. Please have a look. Also any mistake please guide me.

LAN - Allow Browsing is only for 5 IP's

Fin-VLAN

Marketing-VLAN

Quality-VLAN

One more issue that i am facing is
All the VLAN systems need to Disable & Enable the network to Send/Receive Mails or Accessing Shared Folder else share folder or mails will not work. (timeline of 2 to 5 min we need to disable & enable network) Where I need to change this?

Lokesh Kamath

[stephenw10]

Looks like you still have an allow all rule on the Fin-VLAN interface that will catch all traffic before it hits any of the other rules.

@stephenw10
Thank you Stephen.

I will change the Fin-VLAN. Thanks. Other VLAN is correct?

Well they don't look immediately wrong. Without knowing exactly what you need to do I can't say more than that.

That does not seem like a pfSense setting.

Where are you enabling/disabling that?

Can they still reach websites etc without doing that?

@stephenw10
Thank you Steve.

Without enable / Disable they cant use internet, mails, shared folder. In LAN there is no issue.

We are enabling / disabling in Client System Network.

[johnpoz]

that makes ZERO sense and has zero to do with pfsense.. Is your client getting a different IP, new info like dns, etc.. Pointing to pfsense when it wasn't before, etc.

[stephenw10]

Mmm, I could believe it was a rogue dhcp server setting a bad gateway.

Thank you very much Steve.

I have not mentioned any Gateway in DHCP Server.

Please find the below pictures.

Should I Specify Gateway? If Yes pfSense LAN IP is the Gateway right. Also Should I add pfSense LAN IP in Gateway (Routing - Gateway)?

@stephenw10
Thank you very much Steve.

I had given Gateway as mentioned below to each VLAN, but not mentioned in Routing - Gateways Please guide me if anything wrong.

Dude who told you to put in a gateway - there is ZERO reason to do that. What he stated was there might a ROGUE dhcp server handing out the WRONG info!!

[slkamath]

@johnpoz
Thank you very much John.

I will remove that immediately.

@johnpoz, @stephenw10
I do not have any idea on that. please guide me.

Before you go restarting your machines interfaces when something doesn't work... How about you troubleshoot WHY!!!

Are these machines windows? If so then simple

ipconfig /all

from cmd prompt will give you all the info for networking.. Does it show the proper info, what does it show for your dhcp server?

Can machine ping the box your trying to talk to for smtp? Can it resolve its FQDN? Where is this smtp server in your network? Is it outside your network?

[slkamath]

@johnpoz
Thank you very much

When it is not working
1st I will check in pfSense machine will go to ping and select the VLAN and ping the LAN & Google.
2nd I will check in my machine is it working.
3rd I will tell then to disable & enable the network. Then it will work. Now users understood that everytime it is not working then they only disable & enable.

All these machines are UBUNTU. No Windows.

Regarding SMTP i have not tried pinging from client. But I tried pinging google.com & it is pinging.

SMTP is outside network. It's in BIGROCK.IN

So when one machine is failing check the Connection Information in Network Manager.

A rogue DHCP server is some other device that has DHCP enabled on your network that is handing out leases instead of pfSense. Like a soho router you might be using as an access point for example.
