Proxmox: WAN NIC passthrough issue with 2.5G connection to fiber router
-
@stephenw10
there is a conflicting MACwhen internet is working I can see this in arp table,
WAN 100.68.0.1 42:9e:a4:3c:8e:2b Expires in 1156 seconds ethernet WAN 100.69.245.16 7c:83:34:bd:4b:21 Permanent ethernetwhen internet breaks, I get this
WAN 100.68.0.64 42:9e:a4:3c:8e:2b Expires in 1186 seconds ethernet WAN 100.68.0.32 42:9e:a4:3c:8e:2b Expires in 1186 seconds ethernet WAN 100.68.0.65 42:9e:a4:3c:8e:2b Expires in 1186 seconds ethernet WAN 100.69.245.16 7c:83:34:bd:4b:21 Permanent ethernet WAN 100.68.0.69 42:9e:a4:3c:8e:2b Expires in 1186 seconds ethernet WAN 100.68.0.31 42:9e:a4:3c:8e:2b Expires in 1186 seconds ethernet -
Which of those, if any, is the WAN gateway? If it is it's a long way from the WAN IP or a huge subnet.
That doesn't look like it's necessarily a conflict though. One MAC address could be associated with all those IPs.

@stephenw10
the wan gw is 100.68.0.1 42:9e:a4:3c:8e:2b
i can see it in the arp table before and after I lose internet
but sometimes I get incomplete instead of MAC -
Hmm, if it shows 'incomplete' then it's unable to get the gateway MAC which implies a layer2 failure.
Where is the gateway in this case? Remote, at the ISP?
It does seem like you might be hitting an issue with the NIC though.

@stephenw10
i believe the gw is remotely at the isp.
all I have at home is a fiber box that seems unmanaged
is there a way to set static arp?
how would I validate a hw nic failure? -
I've yet to see the i225 disconnect issues that are relatively well known but as I understand it they usually show as the NIC losing link which I don't think you're seeing?
I would run a pcap on it in the failed state and see if it's actually passing packets at all.
-
@stephenw10 that s one of the capture packetcapture-igc0-20241212183144.pcap
-
Hmm, so no incoming traffic at all.
Have you tried running it as not pass-through so pfSense just sees it as vtnet?
-
@stephenw10 i was non-passthrough and had issues hence moving to passthrough
-
What sort of issues? Similar connection failures?
-
@stephenw10 yes, loss of internet
-
Hmm, that does start to look like a NIC issue then if it fails the same way with the Linux driver.
