VLAN issue

securvark · Nov 11, 2018, 12:34 PM

I created a VLAN with ID 50 on pfsense with LAN as its parent interface, re1.50. Created an interface called VLAN50 and gave it an ip 192.168.50.1. In the firewall below VLAN50, I created an allow ipv4 all for now. No outbound NAT has been configured, I just want to see VLAN 50 working for now and be able to ping pfsense from a host.

I am running a bunch of Unifi switches. Firmware is 3.9.54.9373, and Unifi software is version 5.9.29.

I read this thread as well:
https://forum.netgate.com/topic/135525/pfsense-with-unbiquiti-8-port-switch-and-vlans

Basically, I created a network, vlan only, called vlan50 and id 50. Next I created a profile, vlan50 with native network vlan50.

I don't think its necessary, but I created a trunk profile with LAN and VLAN50 selected. The reason I don't think its necessary is because by default, the port config on the switches has all profiles selected so by default, all ports are trunks?

I created a VM under virtual box, with network bridged and created a enp0s3.50 vlan network as follows:
$ cat ifcfg-vlan50

VLAN=yes
TYPE=Vlan
PHYSDEV=enp0s3
VLAN_ID=50
REORDER_HDR=yes
GVRP=no
MVRP=no
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
IPADDR=192.168.50.10
PREFIX=24
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=vlan50
UUID=3d4576d5-da57-4745-b909-3b3340a42d7c
DEVICE=enp0s3.50
ONBOOT=yes

Interfaces are up and I can ping my own ip address. Whatever else I ping, I get network is unreachable. I see nothing on pfsense with tcpdump.

When I ping pfsense on 192.168.50.1, I get destination host unreachable. On pfsense with tcpdump I see the following:
tcpdump -i re1.50 net 192.168.50.0/24 -vvv -nnn

I've been at this for 2 days now reading and digging on the net, on these forums, on ubnt knowledgebase and how to's but I can't get it to work.

Any help would be greatly appreciated!
Thanks!

Looks like pfSense is doing everything it is supposed to, as long as the re1 MAC address is 00:01:2e:78:04:f5.

Sorry. Can't help with the UBNT switch.

You might want to post your pfSense VLAN50 rules just to be sure there's not something silly done there (like TCP-only instead of protocol any).

Thanks, I should have mentioned that, that mac is from re1 interface.

The client config looks good right? So the problem would most likely be in the switch configs.

VLAN interface:
login-to-view

Interface config:
login-to-view

Firewall rule for vlan50:
login-to-view image url)

The only thing I see that might be an issue is the netmask on the pfSense VLAN50 interface (since you cut it off and it matters). Other than that, I'd look at the other gear - either the switch or the virtualbox.

Sorry. I can't really speak to the client config since I don't use virtualbox ever. I can move this thread to virtualization if you like.

Since the ARP request is making it through to the firewall it looks like everything is OK at layer 2.

securvark · Nov 11, 2018, 1:51 PM

@derelict Thank you.

The netmask is /24.

I've posted on the ubnt forums too, can we leave this here for now? If it turns out my switches are oke too, we can move it if that's oke.

A tcpdump on the client shows some weirdness:

The problem was indeed in the switch config, I probably messed that up or something. With the help of the UBNT community I cleared the config and reconfigured it, now its working.
