I'd like to know if anyone is using ipfw with keep-state
and fwd (forwarding). I'm having trouble getting it
to work.
For example, if I have the following:
ipfw add 10 check-state
ipfw add 20 deny tcp from any to any established
ipfw add 30 fwd 127.0.0.1,2525 tcp from _my_net_ to any 25 setup \
keep-state
ipfw add 40 allow tcp from _my_net_ to any setup keep-state
ipfw add 50 deny tcp from any to any
And then
$ telnet 127.0.0.1 25
I get an instant panic (double fault)
If I telnet to another machine
$ telnet some_other_machine 25
the connection is never established but an error is also
never returned.
If keep-state is not used (that is, fwd without keep-state)
everything works fine but unfortunately I need ipfw to be
stateful.
I'm using -current and cvsup'd yesterday.
Any help greatly appreciated.
Juan
