if_pppoe ping works but dns doesn't?
-
Ok since digging an external server does work this seems more like an Unbound issue. Does it stop running? Any errors in the DNS Resolver log?
-
@stephenw10 I just tried using 1400 and it’s giving the same problem.
-
@stephenw10 So pinging in IPv4 i can go up to max of 132. In IPv6 I can do 112 as the size in the ping command. Seems the issue is not the dns resolver.
-
Huh. 132 Bytes total?
What does the interface show the MTU as?
ifconfig pppoe0 -
@stephenw10 Exact 132 bytes
Here's the pppoe info:

Hmm. Can you ping the gateway IP with large packets? Or something closer to you in the route?
I've not seen any other report of MTU issues with if_pppoe. I assume if you just disable it and go back to mpd5/netgraph it passes large pings OK?
-
@stephenw10 So to make sure I decided to do a clean install of pfSense 2.8.1. Same issues.
Using mpd5 I can ping with a size of 1464 (with overhead and pppoe I think it's really sends 1500 right?). I tried switching back to if_pppoe and I can ping the IPv4 gateway upto 132bytes + overhead. I also tried pinging the IPv6 gateway using both mpd5 and if_pppoe and it doesn't respond at all, strangely I can ping v6 external servers tho but in if_pppoe I'm limited to a size of 112bytes + overhead. I'm monitoring cloudflare ipv6 dns server instead of the ipv6 gateway since day one and everything seems ok so far.
Any ideas?

@exomic
The only thing I notice is that you’re using MLPPP with mpd5. I’m not sure whether that could be responsible for such large differences. -
@w0w I’m using Ebox (a child company of Bell Canada). Not sure they support mlppp.
-
Hmm, well that would certainly be an issue, if_pppoe doesn't support mlppp. But I think what you might be seeing is mpd5 just reporting it does support it. It also shows there is only one link in the above log.
But you seem to have proven an issue in your particular setup. I'll see what other tests might be pertinent here.
One thing we discovered recently is that whilst if_pppoe negotiates the MTU/MRU during the connection it doesn't do anything with the result. mpd5 does this correctly. When you use mpd5 hat MTU does the interface end up with?
It's possible your ISP is forcing some low packet size but 132B would be tiny!
-
@stephenw10 By default the wan mtu is 1492 but my isp support baby jumbo frames so I like to set it to 1500 (in ifconfig I see the pppoe mtu at 1500, the vlan interface at 1508 and the raw interface at 1520). Pinging at 1472 (1500 with the overhead) works without any issues using MPD5
-
Are you running any traffic shaping on the WAN?
Check the output of
netstat -I pppoe0 -dfor errors or drops.Lastly try to grab a pcap of the connection negotiation with the ISP in the parent NIC.
-
@stephenw10 I'm not running any traffic shaping at all.

Hmm, nothing obvious there. It sure looks to be trying to use 1500B.
I see plenty on incoming large size packets too but also the Idrop counter being huge.....
Are you able to upload the pcap itself to us for analysis?
Do you see any large outgoing packets at all? Maybe outside the PPPoE stream?

@stephenw10 Sure can you tell me how to upload the pcap and which interface you would like? Also for the large outgoing packets how can I check for that? Thanks
