* Make libalias WARNS?=6-clean. This mostly involves renaming variablesdes2004-07-051-37/+37
| | | | | | | | | named link, foo_link or link_foo to lnk, foo_lnk or lnk_foo, fixing signed / unsigned comparisons, and shoving unused function arguments under the carpet. I was hoping WARNS?=6 might reveal more serious problems, and perhaps the source of the -O2 breakage, but found no smoking gun.

* Mostly mechanical rework of libalias:phk2004-01-171-41/+123
| | | | | | | | | | | | Makes it possible to have multiple packet aliasing instances in a single process by moving all static and global variables into an instance structure called "struct libalias". Redefine a new API based on s/PacketAlias/LibAlias/g Add new "instance" argument to all functions in the new API. Implement old API in terms of the new API.
* Add Cisco Skinny Station protocol support to libalias, natd, and ppp.marcus2003-09-231-0/+4
| | | | | | | | | | | | | | | Skinny is the protocol used by Cisco IP phones to talk to Cisco Call Managers. With this code, one can use a Cisco IP phone behind a FreeBSD NAT gateway. Currently, having the Call Manager behind the NAT gateway is not supported. More information on enabling Skinny support in libalias, natd, and ppp can be found in those applications' manpages.

* A significant rewrite of PPTP aliasing code.ru2000-10-301-4/+14
| | | | | | | | | | | | | | PPTP links are no longer dropped by simple (and inappropriate in this case) "inactivity timeout" procedure, only when requested through the control connection. It is now possible to have multiple PPTP servers running behind NAT. Just redirect the incoming TCP traffic to port 1723, everything else is done transparently. Problems were reported and the fix was tested by: Michael Adler <Michael.Adler@compaq.com>, David Andersen <dga@lcs.mit.edu>

* Added true support for PPTP aliasing. Some nice features include:ru2000-06-201-0/+12
| | | | | | | | | | | | | | | | | | | | - 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. - No API changes! For more information on how this works see comments at the start of the alias_pptp.c. PacketAliasPptp() is no longer necessary and will be removed soon. Submitted by: Erik Salander <erik@whistle.com> Reviewed by: ru Rewritten by: ru Reviewed by: Erik Salander <erik@whistle.com>
* - Added support for passive mode FTP by aliasing 227 replies.ru2000-06-141-0/+2
| | | | | | | | | | | | | | | It does mean that it is now possible to run passive-mode FTP server behind NAT. - SECURITY: FTP aliasing engine now ensures that: o the segment preceding a PORT/227 segment terminates with a \r\n; o the IP address in the PORT/227 matches the source IP address of the packet; o the port number in the PORT command or 277 reply is greater than or equal to 1024.

| | | | | | | | | Add bounds checking to netbios NS packet resolving code. This should prevent natd from crashing on badly formed netbios packets (as might be heard when the machine is sitting on a cable modem or certain DSL networks), and also closes potential security holes that might have exploited the lack of bounds checking in the previous version of the code.
