Hi, same ISP, same problem here. First I played a bit with `iface mtu` and/or `max-payload` in mpd.conf, that didn't help, but I'm not sure exactly what values I tried, some variations of 1492 and 1500. Then I reverted just the `#define PPPOE_MTU` (back to 1492) in `patch-max-payload` and that fixed it, now it works as before. If you want, I can do some debugging, but you'll need to guide me, I don't really know what I'm doing (I just read the changelog _13 -> _14 and guessed). Best regards, rrveex Please show output of ifconfig command for your PPPoE interface with working and non-working version of mpd5. (In reply to fbsdbugs from comment #1) Also, please post your mpd.conf Ok, must have had a typo last night as I played with the conf. Setting `iface mtu` to 1492 does indeed fix the problem with the unmodified _14. _14 with `set iface mtu 1492` or _13 or my_modified_14 w/o any mtu setting in .conf: tun0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1492 _14 w/o setting any mtu in .conf: tun0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1500 create bundle static B1 set bundle enable ipv6cp set iface name tun0 set iface route default set iface enable tcpmssfix set iface disable on-demand set iface idle 0 set iface mtu 1492 # <----- create link static L1 pppoe set link action bundle B1 set link disable multilink set link disable chap pap set link accept pap set link max-redial 0 set link keep-alive 10 60 set pppoe iface igc3 set pppoe service "" set auth authname [...] open Please add the following command to the "startup" section of mpd.conf: log +auth +bund +iface +iface2 +lcp +lcp2 +link Use unmodified 5.9_14, make PPPoE connection and post mpd.log Created attachment 241987 [details]
tail -f daemon.log | grep mpd
This is original _14, still with mtu 1492 in settings.
I couldn't find any mpd.log, grep-ed it out of daemon.log while restarting mpd5 service.
Please note I have 2 lines, same provider, settings, etc.
Supplied log is fine too. Now I need the log for unmodified 5.9_14 and configuration with any "mtu" settings commented out/removed. Created attachment 241988 [details]
mtu1500
Here you go
The problem is that your provider does not specify right MTU size for its side of the link. So, your work-around is right, specify mtu 1492 in mpd.conf. I will post a patch that restores compatibility by default and eliminates need for work-around a bit later. "set link mtu 1492" that fixed also at my side! Thanks, Mistake 'set iface mtu 1492' this fixed it. Sorry for confusion. Created attachment 242001 [details]
proposed fix
Undo all your changes to /usr/ports/net/mpd5/files
Download this patch to /usr/ports/net/mpd5/files/patch-mtu
Rebuild, reinstall and restart mpd5 using configuration without any mtu settings.
Works with the patch without mtu setting. Thank you! Please do not close the PR until the port updated.

The problem may be worked around specifying 1492 for link or interface MTU until upgrade to this revision that restores compatibility.

Created attachment 241339 [details] my working mpd.conf Hello, I recently updated from version 5.9_13 to 5.9_14 of the net/mpd5, and I encountered an issue where some websites would not load. Specifically, I had problems accessing duckduckgo.com, index.hu, and digi24.ro. To resolve this, I had to revert to version 5.9_13. I have included my mpd5 configuration file for reference. Thank you, Zsolt
