[MERGED INTO 16.1.5] MTU > 1492 in PPPoE -- RFC 4638
« on: February 22, 2016, 08:31:46 am »
Hi guys,

The latest development version finally offers GUI support for RFC 4638, we appreciate any help in testing this so it can be merged into 16.1.4 or 16.1.5 for general availability.

The feature ticket is here: https://github.com/opnsense/core/issues/572

The RFC for the avid reader can be found here: https://tools.ietf.org/html/rfc4638


Cheers,
Franco

Couldn't get it to work. I did a reboot and checked ifconfig after setting MTU 1500 in (1)Interfaces>Wan, and (2)Interfaces>PTP>pppoe-advanced. I didn't try setting 1&2 together. I didn't see anything in the GUI; I'm on the latest dev.

I noticed that the MTU info field in Interfaces>Overview>Wan/lan is missing.

Hi windozer,

Can you try to setup all via the interface itself? if your wan connection uses pppoe it will show the size its going to use for the pppoe connection and you shouldn't have to change any advanced settings then.

Thanks in advance,

Regards,

Updated, did setup wizard after factory reset, twice. The Interface>WAN shows "calculated ppp mtu : 1492"

That's correct, you setup the physical layer, the ppp mtu is calculated according to that. So if you want ppp(oe) to use 1500, you need to setup 1508 here.

Okay great. As soon as I type 1508 into the MTU, the "calculated ppp mtu :" changes to 1500. After WAN reconnect, it's working.
