Re: TCP and natd issues
Hello,
I've made progress tracing the cause of my natd issues. I tried
following a suggestion of downloading historical Kernels. Unfortunately
they don't contain IPFW2 and my ipfw kernel module didn't always load
cleanly against them. This problem did however give me another area to
test. (Thanks Simon)
The natd problems only appears when using IPFW2. (IPFW2=yes in
/etc/make.conf during a buildworld). When the kernel (and 2 userland
binaries) are compiled to use IPFW everything works as expected.
I also did some more testing under IPFW2 by setting registry keys to
change WinXPs TCP window size. It had absolutely no affect. TCP sessions
from Firefox are still blocked and the telnet cmd utility is still
unaffected. ("Telnet <google_webserver> 80" and "telnet <mymailserver>
25" work just fine.) I can't identify any distinguishing features
between the two sessions.
This is with todays latest code.
Are there any future plans to make IPFW2 the default ipfw firewall?
Regards
Gary
