Finish updating for the latest alias code. Submitted by: Charles Mott <cmott@srv.net> 1997-05-23 05:34:15 +00:00
MFMP: Make ppp multilink capable. See the file README.changes, and re-read the man page. 1998-05-21 21:49:08 +00:00			`struct cmdargs;`

o Add the -foreground switch. This switch behaves like -background except that ppp stays in the foreground. o Add the -quiet switch to quieten ppps startup o Add the -nat flag and discourage the use of the -alias flag. Both do the same thing. o Correct some nat usage strings. o Change the internal ``alias'' command to ``nat''. 1999-08-19 18:15:52 +00:00			`extern int nat_RedirectPort(struct cmdargs const *);`
			`extern int nat_RedirectAddr(struct cmdargs const *);`
Add a ``nat proto'' command -- similar to natd(8)'s -redirect_proto switch. MFC after: 3 weeks 2001-07-09 00:07:56 +00:00			`extern int nat_RedirectProto(struct cmdargs const *);`

Add the ``nat target'' command. 2000-03-31 14:26:23 +00:00			`extern int nat_SetTarget(struct cmdargs const *);`
Add a ``nat punch_fw'' command for punching FTP and IRC DCC holes through the firewall. 2001-08-02 10:16:32 +00:00			`#ifndef NO_FW_PUNCH`
			`extern int nat_PunchFW(struct cmdargs const *);`

o Redesign the layering mechanism and make the aliasing code part of the layering. We now ``stack'' layers as soon as we open the device (when we figure out what we're dealing with). A static set of `dispatch' routines are also declared for dealing with incoming packets after they've been `pulled' up through the stacked layers. Physical devices are now assigned handlers based on the device type when they're opened. For the moment there are three device types; ttys, execs and tcps. o Increment version number to 2.2 o Make an entry in [uw]tmp for non-tty -direct invocations (after pap/chap authentication). o Make throughput counters quad_t's o Account for the absolute number of mbuf malloc()s and free()s in ``show mem''. o ``show modem'' becomes ``show physical''. 1999-05-08 11:07:56 +00:00
