OK so shall I give it till the morning and post the stats again? It's my mistake really for immediately restarting it I guess, habbit!

Forgive me for being a noob but what does the bearer values mean? How would you resolve a "noisy" line?


Providing the stats tomorrow will be fine.

I'm off to bed now (early start for work tomorrow).
I'll attempt to explain things in some detail tomorrow.

Whereabouts are you?
Can you trace route bbc.co.uk for my amusement? :)

I wonder if the pfSense machine has enough horsepower to do the PPPoE as well as routing.

Does a PC directly connected to the modem and doing the PPPoE improve the speed?

or if the modem is connected to the HH5 does that improve the speed?

As I say it had been running stable for a week, and looking at the stats on PFSense, it's under no stress at all. I'm fairly certain it's managing to keep up.

I could check this later when home!

I noticed a slowdown when I restricted the CPU on the virtual machine running pfSense, so I removed the restriction which solved it. I suppose you would see the CPU maxing out, so it's maybe not that.

What username do you have for the PPPoE session - bthomehub@btbroadband.com?

vhsaccess2 = aint seen that one before?

Are you doing any PPPoE MTU magic? :)

It's on a physical box as had one around. CPU isn't stressed at all, SSD is fast enough and the NIC's are intel so hoping that should keep it from throttling.

Yeah using that username.

vhsaccess2? It will just be standard MTU default of 1500 I think, that's all I've set.

So, I suggest you try a direct connection to the modem to rule out pfSense as the problem.

Try the HH5 instead of the modem to rule out the modem.

Try the modem plugged into the HH5 plugged into pfSense.

Otherwise I suppose it's congestion.

SSD on your pfsense box? That's pretty flash :D

I last used pf at version 1.2.3 so can't contribute anything of worth on that front. If it worked for several days as is, that would imply it probably aint pfsense.

PPPoE MTU is 1492 standard, I think. There's been some talk of pushing 1500 through PPPoE but no black and white on it. Try and see what exactly the current setting appears to be and verify it's actually in place at the shell, too.

It might be worth going back to the HH5 to see if there's any change in speed or obvious changes in routing.

I had one about  ;) :D

OK I'll check it out and maybe try the HH5 whilst I'm at it to see in the meantime.

Exactly! Super inexpensive for a small disk which is all you need!
