But when did this > change? > Here is the summary of changes into libalias(3) and natd(8) since 4.0-RELEASE: - Load Sharing using IP Network Address Translation (RFC 2391, LSNAT) - New options: -redirect_proto, -target_addr and -punch_fw - Removed -pptpalias since this is now done transparently by libalias(3) Note that you DO NOT need -redirect_proto for PPTP through NAT to work, this is now done transparently in libalias(3) and much better: - Multiple PPTP clients behind NAT to the same or different servers. - Single PPTP server behind NAT -- you just need to redirect TCP port 1723 to a local machine. Multiple servers behind NAT is possible but would require a simple API change. Please see manual page for details.
