  • via custom templates
  • via db configuration
AFAIK there is a bug number with it, IIRC correctly the bug explained in one of it's comments on how to do so.

If it was via custom templates, then it wouldn't be mentioned in the release notes.

To find out what db property to use, try:

Code: [Select]
grep -r -i mtu /etc/e-smith/templates

True but that is not what I remembered, I had a search through the bugtracker and found this one: http://bugs.contribs.org/show_bug.cgi?id=549#c41 , so it would be the database.

And according to http://fisheye1.atlassian.com/browse/smeserver/rpms/e-smith-pptpd/sme7/e-smith-pptpd-1.12.0-mtumru_db.patch?r=1.1 it should be something like this:

Code: [Select]
db configuration setprop pptpd mtu xxxx
db configuration setprop pptpd mru xxxx
signal-event remoteaccess-update

Thanks Cactus,

I was just going through the same bug and getting myself confused.

What I want to do is change the MRU of my external interface, eth1.

Not sure if this applies to normal NIC behavior as I believe pptpd is a point-to-point tunneling protocol daemon used for VPN. I am unfamiliar with MTU/MRU, just happened to know the bug.
