pfSense not enabling port

Gblenn · Oct 31, 2024, 1:16 PM

@georgelza Ok but the Proxmox host, vmbr0 and the vmbr30 are on different subnets. So unless you have rules set up to allow them to communicate with each other, they can't.

So either you need to put vmbr30 into the same subnet as vmbr0, or make sure it is possible to communicate between the 172.16.10 and 172.16.30 subnets...

That said, since it is clearly saying it is UP, and it is also getting an IP, my guess it is working fine here.
So the card and the module are ok to use with Linux (Proxmox at least). And it is likley only with pfsense (freebsd) that you will have an issue, which you will be able to solve when the DAC and/or new module arrives.

stephenw10 · Oct 31, 2024, 1:16 PM

You are seeing the replies from 172.16.30.11 which implies the pmox1 is using it. Which we know it is.

Host unreachable implies it cannot ARP for the address so a layer2 failure.

georgelza · Oct 31, 2024, 1:21 PM

@Gblenn Let me go check...
I know my MBP that sit on 172.16.20.29 has full access to everything on 172.16.10.0 ... need to confirm I have a rule that allows similar to 172.16.30.0
sure i did check, but lets recheck/verify ;)

@stephenw10 Hmm, I missed that it was actually two different IP's there. So I guess the ping was meant to have been to 172.168.30.11? Where the .1 belongs to pfsense VLAN where that .11 IP was actually handed out.

Anyway, I think the DELL module is working on Linux and the DAC and new Fiber module will fix it.

stephenw10 · Oct 31, 2024, 1:27 PM

Well it looks like 172.16.30.11 to 172.16.30.1 to me. And it's failing which implies it cannot ARP for it inside the same subnet.

that last rule is never used as as it already allowed by second.

@Gblenn ye... but at the moment, going from the topton hosting pmox through fiber onto unifi sfp+ port 1, and then via my 2.5GbE Cat 6 uplink to pfSense is failing.

vLan30 with 172.16.30.1 lives on igb1.30 at the moment.

@georgelza said in pfSense not enabling port:

As per suggestion, see below. Looks good, vmbr30 which sows up

root@pmox1:~# ip a

inet6 fe80::aab8:e0ff:fe05:f091/64 scope link
valid_lft forever preferred_lft forever

Hmm, perhaps it isn't working after all. Just noticed that you have the NO-CARRIER notification = No cable connected?! As well as it is not enabled as in "noop state DOWN group".

Further on the vmbr30 there is no LOWER_UP as in the physical connection at the link layer is not there?? Compare vmbr0 to vmbr30:

vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP>
vmbr30: <BROADCAST,MULTICAST,UP>

What does it look like in the Proxmox UI, for the host and the listings under network?

georgelza · Oct 31, 2024, 2:01 PM

@Gblenn see above.

The UI implies it's up...

guess i need to say i wait... this is rightly not a netgate problem... well until i install the DAC cable from the Topton running pfSense into y core switch.

This atm is more unifi/Topton comm...

netgate/pfsense related though, at the moment it's not allowing me to specify a default gw or simply a gw to use for the 172.16.30.0 network.

i can ping from the pmox my 172.16.10.1 gw, but that's going via the 2.5GbE copper link, to switch and onwards to pfSense to the igc0 port

No, the UI only sais that it is administratively activated.

Here's what it looks like for me if I disable the switchport that my 10G link is connected to, same as you have: NO-CARRIER and no LOWER_UP.

3: enp10s0f0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq master vmbr1 state DOWN group default qlen 1000

And this is what the UI is showing me...

@Gblenn
ok, interesting... figured that implied it was working...
even though as you said ip a actually said otherwise.

so it's starting to look like the Pmox host is also not linked to the Unifi pro max...

wondering if this is caused by the switch... think i might need to "engage" some patience and wait for that 2nd SFP+ to arrive and then the DAC cable and then see from there.
Will first try them on the pmox host, as it's more compatible with anything and confirm they work, then if all good there then move them to the pfSense host.

Hmm, do you always assign IP from Proxmox? I'm not sure what Proxmox will do in this case... as I would imagine it is Proxmox handling the ICMP request within it's virtualization environment.

If you had a VM that you assigned vmbr30 to (leaving the ipv4 part empty), it would be assigned an IP from pfsense instead. You don't need to put it in any VLAN, as that is only complicating things when testing... But if you want to, it's just a matter of entering the VLAN tag in the field for the VM's interface instead.

But still, the fact that it shows the link is not UP at the interface level, makes me wonder...

georgelza · Oct 31, 2024, 2:31 PM

@Gblenn I figured i'd give the host a ip on the network the card lives.
i will then give the guest vm's their own ip's on that network also.

can easily remove that 30.11

stephenw10 · Oct 31, 2024, 2:36 PM

The status of the bridge device is not really important compared to that of the actual NIC. The bridge could appear up even if the NIC is not.

I would check the NIC stats and see if you see any incoming packets on it. ip -s link show enp4s0f0

Leave all that to pfsense instead, that's where you want to control all those things, including all your static IP's. If you have set up the Unifi SFP+ port as VLAN 30 Untagged, then anything on the Proxmox side will of course get an IP from that range.

@stephenw10 It's already in the info pasted above, showing NO-CARRIER and DOWN so it doesn't seem to be working unfortunately...

georgelza · Oct 31, 2024, 2:40 PM

@Gblenn

I normally do dhcp reserve assignment on pfSense for all devices... aka control/manage i from that side.
