try adding this before all the rules..
/sbin/ipchains -M -S 7200 10 160
Also, is the 192.168.100.1 the default gateway?
thanks,

My problem is that i keep getting errors from users sending mail to my
exchange server, about 50% fail with this message.....
------Transcript of session follows -------
[EMAIL PROTECTED]
Remote connection was abruptly disconnected.
the line seems to be fine it does not disconnect.. telnet to the box from
outside works fine no drop outs, if i connect with pcanywhere to the
exchange box i keep getting timeouts (i do portfw on the approprite
pcanywhere ports)...
i think the problem is with the ipmasqadm portfw routine.... as the ipchains
section seems to work without a hicup.....
please HELP!!!!!!
Thanks Geoff Gauci
