Subject: clampmss only partially working on 2.6 kernelmode pppoe?
Date: Sat, 12 Feb 2005 07:41:40 +0100	[thread overview]
Message-ID: <afcf620205021122413dd5dd6d@mail.gmail.com> (raw)

Hi,


I have linux 2.6.11-rc2 masquerading a pppoe connection (mtu: 1492)
trough the kernel mode pppoe implementation.

I loaded the ipt_tcpmss and ipt_TCPMSS (what's the difference?) kernel
modules, and have the following iptables rule running:
iptables -I FORWARD -o ppp0 -p tcp --tcp-flags SYN,RST SYN -j TCPMSS 
--clamp-mss-to-pmtu

Most internet hosts seem to be ok, but (don't laugh, it's for a family
member's fade-out only!) hotmail still is a pita. (to be specific:
after logging in, the inbox page served by
by18fd.bay18.hotmail.msn.com never gets trough). Some hotmail submit


Has someone experienced something similar?

Is there a more precise test method (eg, sending a packet of a certain
size to a certain host or something, or is there something specific I
could look for in a network dump?)

Any suggestions on how this could work?
