Hi,
i installed a FBSD 4.1.1 machine to serve as a dsl-router using user ppp
and -nat. Unfortunately I have the same windows problem (don't fragment)
as most other users. Setting the MTU under Windows 2000 works fine and
everything loads quick. Setting the MaxMTU under Windows 98 does
unfortunately not work. The system is slow and laggy.
Now i would like to use tcpmssd but everytime tcpmssd gets a packet
it core dumps (bus error).
Using rl0 with
ipfw add 100 divert 1234 tcp from any to any out via rl0 setup
and
/usr/local/bin/tcpmssd -p 1234 -m 1492 -v
doesn't work as the packets go out via tun0 (tcpmssd doesn't
core dump either)
Using tun0 with
ipfw add 100 divert 1234 tcp from any to any out via tun0 setup
and
/usr/local/bin/tcpmssd -p 1234 -m 1492 -v
should work but tcpmssd core dumps.
I also tried to filter the packets on coming in on dev ed0 (even
if this probably makes no sense) and tcpmssd still core dumps:
ipfw add 100 divert 1234 tcp from any to any in via ed0 setup
/usr/local/bin/tcpmssd -p 1234 -m 1492 -v
Here is my configuration:
ipfw show:
