0.2.5
=====
- 2-Dec-2002: - fixed a bug in check_vialoop. It wrongly claimed
to have detected a loop when using the old-style
IP address based inboud/outboud definitions.
0.2.4
=====
- 23-Nov-2002: - released 0.2.4 (feature enhancements)
@ -10,7 +16,6 @@
change of IP address.
- 13-Nov-2002: - working on portability - goal is building on *BSD
(feedback from Georg Schwarz)
0.2.3

@ -40,11 +40,15 @@ HOW TO GET STARTED
- make install
- edit /usr/etc/siproxd.conf according to your situation
At least 'host_inbound' and 'host_outbound' *must* be adapted!
'host_inbound' is the firewalls IP address of your private network,
'host_outbound' is the publich IP address or hostname of the
firewall. (If you have dynamic IP addresses, then you might want
to use a hostname here and use a dynamic DNS service like [1])
At least configure 'if_inbound' and 'if_outbound'. The must represent
the interface names (eg. on Linux: ppp0, eth1) for the inbound
and outbound interface.
** The use of 'host_inbound' and 'host_outbound' is deprecheated!
'host_inbound' is the firewalls IP address of your private network,
'host_outbound' is the publich IP address or hostname of the
firewall. (If you have dynamic IP addresses, then you might want
to use a hostname here and use a dynamic DNS service like [1])
- edit /usr/etc/siproxd_passwd.cfg if you enable client authentication
in siproxd.conf

===============================
- supports Linux and FreeBSD (other BSD derivates not tested)
- SIP Proxy for SIP based softphones hidden behind a masquerading firewall
- Includes an RTP data stream proxy for *incomming* audio data
(outgoing RTP data should be handled by IP masquerading by the firewall)

dnl @synopsis ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
dnl
dnl This macro figures out how to build C programs using POSIX
dnl threads. It sets the PTHREAD_LIBS output variable to the threads
dnl library and linker flags, and the PTHREAD_CFLAGS output variable
dnl to any special C compiler flags that are needed. (The user can also
dnl force certain compiler flags/libs to be tested by setting these
dnl environment variables.)
dnl
dnl Also sets PTHREAD_CC to any special C compiler that is needed for
dnl multi-threaded programs (defaults to the value of CC otherwise).
dnl (This is necessary on AIX to use the special cc_r compiler alias.)
dnl
dnl If you are only building threads programs, you may wish to
dnl use these variables in your default LIBS, CFLAGS, and CC:
dnl
dnl LIBS="$PTHREAD_LIBS $LIBS"
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
dnl CC="$PTHREAD_CC"
dnl
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE
dnl to that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
dnl the default action will define HAVE_PTHREAD.
dnl
dnl Please let the authors know if this macro fails on any platform,
dnl or if you have any other suggestions or comments. This macro was
dnl based on work by SGJ on autoconf scripts for FFTW (www.fftw.org)
dnl (with help from M. Frigo), as well as ac_pthread and hb_pthread
dnl macros posted by AFC to the autoconf macro repository. We are also
dnl grateful for the helpful feedback of numerous users.
