[pptp-server] Negotiating MRU with Win2k?

[Neale Banks]

G'day,

Here's what I see when PPTP comes up and PPP negotiates with Win2k (I
have "mtu 1490" and "mru 1490" in my options):

-----------------------------------8<-----------------------------------
Oct  4 10:58:10 gull pppd[332]: Connect: ppp0 <--> /dev/pts/0
Oct  4 10:58:10 gull pppd[332]: sent [LCP ConfReq id=0x1 <mru 1490> <asyncmap 0x0> <callback CBCP> <magic 0x38a33e9a> <pcomp> <accomp>]
[...]
Oct  4 10:58:11 gull pppd[332]: rcvd [LCP ConfNak id=0x1 <mru 1500>]
-----------------------------------8<-----------------------------------

Ditto if I try to negotiate 1480.

As I see it, I asked that the max size to be sent over the ppp link be
1490 but was subsequently NACKed and told that it would be 1500.

The symptoms I'm seeing include being able to get the front page a
webserver that's down the tunnel but neither of the frames on that page
(the front page is only 230 bytes and I'm guessing that each of the frames
are >> 1400 bytes).

Any ideas?

Thanks,
Neale.
