sendto: 65 with UK ISP and PFsense

[stephenw10]

Send to error 65 implies there is no route to the gateway.
Though the fact it shows 'dynamic' there and not the actual gateway IP implies the PPP session has gone down, is that the case? Does it show down in Status > Interfaces?

You can still reach the modem interface so it doesn't appear to be a problem with the link there.
That also means you could run a packet capture on that interface and see the PPPoE traffic, if there is any.

First thing to do though is check the PPP logs to see what happened when it failed.

@stephenw10 Thanks for the reply.

And the logs at the time of it going down.

[stephenw10]

Those are the logs after it disconnected showing it trying to reconnect.... and failing.

Really the logs covering when it actually failed would be be better. It does look like it's at least receiving something though.

@stephenw10 I shall have to wait for it to fail again as the logs doesn't show anything before then.

I shall keep you updated

[F022Y]

So it actually went again but before just rebooting the draytek modem I tried a few things.

In ESXI i disconnected and reconnected the WAN virtual NIC - no difference
Rebooted PFsense VM - No difference

Here are the logs and what i saw.

As per before i reboot the modem and the link comes back.

[stephenw10]

What I expect to see there is either something like 'LCP echo timeout' or something from the servers side closing the connection. Unfortunately those would have been imediatelt preceding those logs if there were there.

[F022Y]

@stephenw10 Sorry nothing like that

[stephenw10]

Hmm, that implies it was closed deliberately for some reason. What do the system logs show at that time?

[F022Y]

@stephenw10 Status > System Logs > System > General doesn't show anything at that time.

I had snort installed but in monitor mode (no action) as a step i've removed it as it wasn't doing anything. I do have PfBlocker installed too if that has any baring.

[stephenw10]

The system log would at least show the WAN going down at that point, the gateway monitoring failing etc. There must be something shown?

[F022Y]

@stephenw10 So under Gateways i have this at time of fail.

From PPP

None of the other logs show anything at that time.

[stephenw10]

Nothing in the main system log? I expect to at least some duplicated entries there.

[F022Y]

@stephenw10 Where should I be looking in case im being stupid?

[stephenw10]

In the main system logs in Status > System Logs > System Tab you wiulkd usually see most of the ppp entries as well as gateway entries and, importantly, other things that may have triggered the connection to close.
"connection closed" is not normally the first log entry like that. If it was caused by something like the parent interface loosing link, that's where it would appear.
Trying to find an example but my own PPPoE has been up so long it's scrolled out of the logs.

[F022Y]

@stephenw10 In which case thats the logs i've given just dies off. Could it be the Vigor166 then? I have it in modem/bridge mode

[stephenw10]

This is what it looks like if the parent NIC loses link for example:

Your logs do not match either.

@stephenw10 Is there an export function of all the logs? Just thinking when it next happens i just export everything.

[stephenw10]

You can just download the full log files. The main system log for example is:
/var/log/system.log

You can download that from Diag > Command Prompt.

@stephenw10 Thank you for the help, i've cleared the logs and will wait to see if it dies.

[F022Y]

So it all went again today I've grabbed the logs for someone to see if i've missed anything but these are the screenshots along with one from the draytek that shows a link (shows wrong date as in modem mode).

I'm really struggling now.
