Pfsense-1.0.1-CVS-12-28-2006 / MTU does not change

[gbosco]

from webgui - changing MTU on a PPPoE connection / WAN, does not work.

I set MTU = 1000 under "interfaces" -> "WAN" (pppoe) and reboot.

after reboot, pppoe get established - but launching ifconfig, returns:

ng0: flags=88d1 <up,pointopoint,running,noarp,simplex,multicast>mtu 1492
        inet 87.15.65.174 –> 217.141.109.24 netmask 0xffffffff
        inet6 fe80::240:f4ff:fe8a:485f%ng0 prefixlen 64 scopeid 0x7

Looking into /var/etc/mpd.conf:

...
set link mtu 1492
...

/gbosco</up,pointopoint,running,noarp,simplex,multicast>

There have been no changes related to any of this…

[gbosco]

does it work for you, changing PPPoE MTU?

I don't use PPPoE.  Regadless, no code has been changed in RELENG_1 that has anything to do with MSS/MTU, etc.

mpd has three mtu change points
link_Mtu
link_mru
iface_mtu

all can be found in /etc/inc/vpn.inc under the pppoe function.

test first with ping to see where this needs to be before you start to set it
