Once upon a time David Carmean shaped the electrons to say...
>But I can't! It only seems to be changed when *negotiated*, but I can't set
>it from RADIUS or from the user table.

If a user uses PAP or CHAP - WE CANNOT CHANGE MTU!

MTU is negotiated BEFORE PAP and CHAP - that is the way PPP is. Since MTU
needs to be set *before* we know who a user is, we cannot use the info in
their user entry to set it. So it gets set to the standard, less if they
request it.

If the user uses a chat script then we know their settings before PPP, so
we use it in MTU negotiation.

I ran into this months back and posted about it here.

There is simply no way to use a users settings to set MTU when the user
is using PAP or CHAP.
