Re: [pfSense] Setting PPPoE MTU
I should add: when I Click Here for Advanced and MLPPP options (takes me to interfaces_ppps_edit.php) I don't see any settings relating to MTU/MRU. But in the HTML there are 6 hidden tables. tr style=display: none id=link0 td width=22% valign=top id=linklabel0 class=vncellLink Parameters (bce0)/td .. table with rows for bandwidth, MTU, MRU, MRRU /td /tr .. repeat for link1 to link5, although they don't show (bce0) It seems to me that at least the link0 entry should be shown. I don't see any MTU/MRU/MRRU options even if I select two ethernet interface under Link interface(s) Maybe some Javascript which is supposed to be un-hiding them isn't doing so? But I don't see any errors in Javascript console. I'm using Chrome 32.0.1700.102 under OSX. I have also tried Firefox 26.0 - no difference.

The connectivity is fine, but the MTU is 1492 and I would like to bump this up to 1500 (assuming the router will take ethernet frames which are 1508 bytes). I looked at this about a year ago when we started getting clients with FTTC connections here in the UK (which are basically VDSL), and at the time it looked like RFC4638 support (baby jumbos) wasn't supported in pfSense. I've just done a quick search for 'pfSense RFC4638' and found this thread from May last year: https://forum.pfsense.org/index.php?topic=61876.0 which seems to indicate that the underlying BSD support is now there. Whether that means 2.1 supports RFC4638 is something perhaps one of the devs can answer? As an aside, I wonder if it might be possible to 'bodge' it by increasing MTU for the parent interface. So, looking at one of of my pfSense's, for example, the PPPoE interface is on vr2, so I'd create a new interface (after creating the PPPoE interface on WAN) called 'WANModem', and given that interface an MTU of 1508. Then go back to the PPPoE WAN page and increase the MTU there to 1500. Creating a 'WANModem' or similar interface also allows you access to the web interface on your DSL modem, which can be useful for checking line sync speeds and the like, which might otherwise not be visible to a PPPoE connection.

I find that I can happily set the MTU to something *lower*, e.g. setting 1480 either on the main WAN page or on the per-link settings gives me pppoe0 with MTU 1480. However if I try to set MTU 1500 I still get pppoe0 with MTU 1492. Checking /var/etc/mpd_wan.conf I find set link mtu 1500 so the value I entered has ended up in the right place. Something else is clamping MTU or MRU to 1492. ___ List mailing list List@lists.pfsense.org http://lists.pfsense.org/mailman/listinfo/list

I'm in the UK too. The line I'm discussing is ADSL on Plusnet. (*) I've just done a quick search for 'pfSense RFC4638' and found this thread from May last year: https://forum.pfsense.org/index.php?topic=61876.0 That's useful, thanks. Doing a tcpdump on the WAN interface, after the initial PADI exchange (which doesn't include a PPP-Max-Payload tag) I see that at the LCP stage, pfsense is offering MRU=1492, whilst the BRAS side is offering MRU=32725 Regards, Brian. (*) At home I have FTTC on Plusnet, and that definitely works with MTU=1500. However I'm using their provided router, which does PPPoE to the BT VDSL modem. I'd like to be able to change to pfsense at some point. ___ List mailing list List@lists.pfsense.org http://lists.pfsense.org/mailman/listinfo/list
