VLANs have no DNS
-
Hey guys! So I have been having some issues getting the DNS side of my VLANS to work. I have setup all the vlans and the switch is passing traffic on the VLANS but for the life of me I cant get the internet to stay up. The servers keep saying that they can't connect to the DNS server on the VLANs and the firewall rule is set on each VLAN for any<_>any and for some reason im not able to get all 6 VLANS to stop talking to each other and I have already configured DNS and the network that has no VLAN has no issue connecting to the internet which is LAN. please let me know if you have any ideas. Thank you!

@natethegreat21 Pictures don't correspond to the text you wrote at all.

@natethegreat21 said in VLANs have no DNS:
VLANs and the firewall rule is set on each VLAN for any<_>any
no they are set for ANY <-> WAN NET .... which is basically only allowing access to your WAN_IP and your WAN_gateway

Im sorry I attached a wrong screenshot. I have a bunch. It is any<>any please see attached

@bob-dig I noticed that the screenshot I posted was not correct for the firewall rules. Sorry about that, please see below
-
@natethegreat21 Everything should work now.

@Bob-Dig I rebooted the firewall and the switch and im still getting a DNS error. Yes I did flush the DNS as well.

@natethegreat21 Does connectivity work if you hard code the IP address, subnet mask, gateway and DNS server on one of the devices that doesn't work.
This would verify that its not a vlan issue with the switch.
What does your vlan definition page in pfSense look like ?
-
@nogbadthebad That didnt seem to help. Which page are you looking for exactly sorry
-
@natethegreat21 so when adding them as a static dns didn’t work but a ping to the interface did?
I’m wondering if it’s an issue with your managed switch.

@nogbadthebad Its very possible. Let me factory reset the switch and try to see if that helps after I configure it again
-
@nogbadthebad You were spot on! This switch is having issues again. Thank you so much! Do you recommend anything to replace the Netgear GS754T that I have, please?

@natethegreat21 I'd be looking on ebay for some Cisco small business switches that support vlans & POE.
