Setting up a VLAN part 2
-
ok, just added a 24 port vlan switch and added a 3rd vlan…vlan 200 172.10.10.x
now that i figured out the tagging/untagging, it was pretty easy to configure the switch.
i must say, documentation is key with vlans. i logged into the switch and used the port name and wrote in the vlan it belongs to, but i also have it written down on paper.
this is what my switch config looks like (this switch doesnt use E for exclude, it uses N, which has been posted already).
vlan1- U U U U U U U U N N N N N N- 192.168.1.x
vlan100- N N N N N N N N T U U U N N- 10.10.10.x
vlan200- N N N N N N N N T N N N U U- 172.10.10.xi was able to hit the internet with a PC using a dhcp address from the 172 range and i stopped at 14 ports.
now that i got the hang of this, linking another VLAN switch should be easy. i just need to make sure that i tag the ports on the other switch to work with the respective vlans...1, 100, 200

That's true until you hit unmanaged switch, then you can use only one vlan on that port of managed switch and that should be untagged

right, if i want to do multiple vlans on other switches they need to be vlan switches. i follow what you are saying.
right now one of the untagged ports for vlan1 is plugged into a 16 port netgear switch, that switch can only operate on 1 subnet since it isnt vlan capable, in this case 192.168.1.x.
-
finished adding some block rules to stop traffic between vlans. disabled it one way to test, enabled it again, did some more testing, the rules did exactly what they were suppose to do.
dns question- i can ping other IPs, but i cant browse by going to \pc-name
any idea what i need to do to get that working?
i can access \ip-address w/o any issues, which is why i assume DNS.
the dhcp server settings for LAN is what i used as a template for vlan100 and 200 and my LAN DNS lookups work fine.

where you do have dns setup?

You can also use another vlan if you require

I assume you are using DNS forwarding on pfSense for your DNS service. That's the default.
You can have pfSense add any client that sends it's host name to the local DNS table.
Go to Services: DNS Forwarder: and check 'Register DHCP leases in DNS forwarder'.This will only kick in when clients renew their DHCP lease so you may have to force that to test.

it is the default setup. the only thing i did was point to OpenDNS servers for lookups (and removed the first entry of 127.0.0.1).

ok, just did this, i will delete DHCP leases and remote reboot machines and see if that fixes it.
EDIT- now that i think of it…the device i was trying to access by hostname was statically assigned, this option looks like it is only DHCP related. that device will never ask for a new address since it is static.
-
You can add static dhcp IPs with an option on that same page. Or if you have statically assigned the IP on the client itself you can add it manually in the host overrides table at the bottom.
If I need to have anything static I always use static DHCP rather then IPs coded at the client. It makes this sort of thing far easier. Also if I do have to change the IP ever it's all centrally stored.

makes sense and i am going to look into that, thank you.
ok, i did that, i added the entry for the static device.
when i ping it, it resolves to a public internet address not the internal IP…..hmmmm

You may have to clear the local dns cache. Make sure your client is using the DNS forwarder.
You can try using the Diagnostics: DNS Lookup: tool to check pfSense can resolve it correctly.Steve

DNS lookup in pfsense can see the correct name if i type in the ip and it shows the correct ip if i type in the name.
but it uses 127.0.0.1, then 208.67.222.222, 208.67.220.220, finally 192.168.1.1
i do want my machines to use openDNS server for external lookups, but obviously not for internal lookups, which is what i think it happening, but i could be wrong.
local cache cleared and my ipconfig looks like this
ip- 172.10.10.210
sub- /24
gate- 172.10.10.1dns- 172.10.10.1
-
127.0.0.1 is the local machine, which it is checking first. That seems correct. I don't know why it's looking at 192.168.1.1 though, that sounds wrong.
See my screenshots.Steve
-
i know 127 is localhost, but i removed that from the DNS page.
my DNS forwarders are 208.67.222.222, 208.67.220.220, and 192.168.1.1 (for devices that sometimes grab 3 DNS IPs.
although, 192.168.1.1 might be wrong and i probably shouldn't keep it in there now that i no longer have a flat network.

You mean in System: General Setup: DNS Servers: ?
That should only list external DNS servers that pfSense uses for DNS resolution.

ok, no problem, i will remove the 192 entry, if i do that, then only the openDNS servers remain, but those are in spot 1,2 right now so i dont think it will fix my issue, but i will still remove it.
thanks.
-
Ok. Well yes it has to first use the local DNS table so 127.0.0.1 should show first as in my screenshot.
Where exactly did you remove 127.0.0.1 from?pfSense will always use the local DNS table first unless you have checked 'Do not use the DNS Forwarder as a DNS server for the firewall' in System: General Setup: DNS Servers:

i didnt remove it, i thought i saw an option to uncheck the use of it.
-
Hmm, that looks fine. Exactly as I have mine set.
Yet when you use Diagnostics: DNS Lookup: it doesn't use 127.0.0.1?
Steve
-
ok, i just added 127.0.0.1 as the first entry and bumped down the openDNS servers.
