WAN periodically Rebooting
-
Earlier Draytek modems had several different firmware versions for different line conditions. I don't known if that's still true for the V166 but if it is you could try a different one.

@stephenw10
Hi Stephen,..I did upgrade the Draytek to the lastest firmware available,..
Maybe worth raising a support call with Draytek? -
Yup may as well. They may have alternative firmware you could try.

https://www.draytek.co.uk/forum/dsl-specific-questions/24943-draytek-166?start=6Just found this on the Draytek site....
-
Hmm, well that would be painful.
Might need a TLDR post here as I can't recall excatly what you've tested at this point! You still saw disconnects with the Openreach modem(s) though?
-
@stephenw10
Yes,.. was thinking this post was getting a little like war a peace,.. with nearly 160 posts...
Draytek log support opened,.. their sending me some tests to do... -
@diyhouse Interesting, Can you attach a screenshot of the WAN interface ? What are your MTU/MSS settings for WAN ?
-
@VioletDragon
Sorry,. missed you post,.. ( lot going on this end )
Currently Draytek are looking at my logs of how / when the link closes etc,.. as they have said everything looks good to them... well at least from the screen shots.
MTU is set to 1492
-
Can you make the Draytek do the PPPoE connection and see if it still drops?
-
@stephenw10 Yes,.. was wondering to do that,.. as at the end of the day,.. one critical part of the puzzle we have not eliminated is the pfsense box itself,.. maybe h/w or config issues,.. unlikely but not impossible..
I think I have re config'd the Draytek to handle to PPPoE,.. and I think I can just connect the modem to one of the spare ports on the pfsense box,.. and add rules to just route all ( ipv6/4) traffic from a 192.168.3.0 network to 192.168.30.0 network...
This should then preserve all my 192.168.3.0 DNS mapping etc,.. and should be transparent to my overall network,..
Are my thoughts assumptions correct? Tx for any guidelines... -
Yes that should work. It may have some sort of DMZ feature to just forward all traffic to the internal pfSense WAN IP.
-
@stephenw10 Hi Guys,..
Well bit the bullet,.. and connected the draytek directly to the DSL connection, and let it manage the connection.
Good news I achieved a good solid connection that appeared stable during two sessions of 40min and 50mins... not the 3 or 4 mins as before with PPPoE and pfsense.
'My' only problem, was my lack of understanding... ( I believe ).
I naively thought that placing the Draytek on another LAN ..6.0 network, and creating a rule to pass all traffic between my 'base LAN on ...3.x' would suffice.
Nope,.. the penny dropped as I realised I was no longer routing my DNS lookups to the correct LAN and device, So I thought/belive. As I still want pfsense to manage my security and DNS...
I tried numerous DNS re-configs, that I could find and think off, as well as numerous Rules, but alas I did not strike lucky.
Can someone enlighten my how I get Pfsense to point to the Draytek, ( IP 192.168.6.20 ), I assume this is how I point to it. and what rules I actually need...
Also the big question now is why does pfsense not hold a continuous connection,.. but lets save that for a rainy day.. Is it my config and 'rules'.
Oh and needless to say when I connected back to original h/w config... that to was broken,.. ( thank goodness for config backups,.. and the ability to restore selected parts,.. fantastic. ) But I still had to reboot my working PC,.. I suspect it to,.. was confused by DNS as well..
Ah thoughts..
Thankyou in anticipation...

What I'd expect to see would be the pfSense WAN connected to the Draytek in the new subnet.
Traffic from pfSense would still be routed via the WAN but just not using PPPoE.

@diyhouse Hello,
I'm not sure how much help this will be now you're letting the Draytek modem manage the VDSL connection, but I use the same modem (Vigor 166) in bridge mode with pfsense+ (sg2100). My internet connection is FTTC (no FTTH here yet either) provided by Zen. I've always had problems with frequent dropouts with the stock firmware to the point the modem was unusable (many times a day). In the end I got in touch with Draytek support and they sent me a link to access a different firmware (4.2.5 RC2 MDM6), which solved the problem. I don't get the uptime mentioned in this thread but two to three weeks between DSL resyncs is typical. -
@youngy said in WAN periodically Rebooting:
Many tx for your input suggestion..frequent dropouts
Yes that s exactly my issue,... If I could get 2 or 3 weeks between reconnects that would be great.
I have sent a note to Draytek requesting a link to the Firmware you suggested -
@youngy Had a response from Draytek,.. as follows:-
Please see link below to requested firmware https://fw.draytek.com.tw/Vigor166/Firmware/v4.2.5/ However is from the .com website and is more suitable to infrastructure from outside the UK. So we cant guarantee that this will work properly but you are welcome to test itMay I enquire of your country of use... and your ISP provider,.. if you dont mind..
KR -
Looks like he's on Zen so the UK.
The release notes make it look like MDM6 is worth trying:
"Vigor166_4.2.5_MDM6.zip" provides Annex A modem code 129120_05, and 128210_02. (Recommended when meeting VDSL sync issue). -
Though I'd probably try 4.2.7_MDM6.
It's interesting that your current firmware shows as 4.2.7_BT so maybe tuned for BT/Openreach?
-
@stephenw10 Not sure if its the same equiv,.. but there's also a 4.2.7 MDM6.zip
Humm,.. same improvements ? who knows...??
what are MDM versions..? -
@diyhouse Hello, yes I’m in the UK with Zen. I contacted support@draytek.co.uk and they sent a link to the firmware. I tried newer *_BT firmware but still get the frequent drops so went back to one I mentioned above. I hadn’t seen the 4.2.7_MDM6 version but can try it and let you know how it goes. Is the link on the draytek UK website?
