Intermittent "no route to host" on my LAN-port

Derelict · May 24, 2017, 7:45 PM

As far as I know, almost nobody is using those sk NICs.

At the same time I haven't heard of anything like what you're seeing either.

192.168.1.0/24 link#11 U sk1_vlan
192.168.1.1 link#11 UHS lo0
192.168.1.3 link#11 UHS lo0
192.168.2.21 link#11 UHS lo0
192.168.2.21/32 link#11 U sk1_vlan

Why are both of those on link #11?

netstat -rnWfinet

1.1 is the router itself
1.3 is a virtual ip
2.21 is a virtual ip

192.168.1.3/32 LAN IP Alias Virtual IP for wpad.malmberg.fi
192.168.2.21/32 LAN IP Alias Virtual IP for wiki.malmberg.fi

I also realized that I have had it defined as 1.3/24 instead of 1.3/32 - this I have now changed.

I have run your suggested netstat -command BEFORE and AFTER this change.

1.1 is the router itself
1.3 is a virtual ip
2.21 is a virtual ip

192.168.1.3/32 LAN IP Alias Virtual IP for wpad.malmberg.fi
192.168.2.21/32 LAN IP Alias Virtual IP for wiki.malmberg.fi

So you're playing games with multiple Layer 3 networks on VLAN 5 and you are having problems. Perhaps don't do silly things like that. Makes me wonder what other questionable design decisions you have made elsewhere. Seems they are coming home to roost. What kind of switch are you using? If you post more packet captures please indicate where they were taken and how.

So, the 192.168.2-base ip is now gone. I will look into adding a network solely for my HAProxy addresses some other way, perhaps using a VLAN which is only available on pfSense or something along those lines. But I will leave that for now as it most obviously can be a part of the problem. I added 1.6/32 as a VIP instead to serve my wiki.

My packet dumps are from pfSense.

My switch is a Procurve 2848 (J4904A).

Let's see if the removal of the VIP makes a difference.

It would be foolish to say that this was the only questionable design I have made, although most of my decisions are preceded by somewhat thorough investigations.

From pfSense, capturing 192.168.1.1 this time.

The pinging is done from 1.191.

I would try a different NIC. Or capture on a monitor port on the switch and see if the pings are really going out on the wire.

Almost nobody uses those sk NICs.

I'll go ahead and move my ports around a bit later tonight just to cross out the possibility of hardware failure.

I've liked the idea of using these Watchguards as they are "proper" pedigree firewalls. I have been looking at migratiing to an XTM-series, but I just had huge issues getting the latest nano-release even starting on that one.

Both the primary WG and my secondary WG got totally screwed up and wont even boot in an orderly fashion.

Luckily I took a backup before venturing into testin.

As a workaround, I installed pfSense on proxmox, hooked up my VLANs and now this technically works. Technically, not optimally - because now I'm firewalling in the host-environment where my crownjewels are, instead of firewalling before even touching this hardware. But for now, I'm in business again.
