This a free PPPoE redirector for Linux.基于LINUX环境下的PPPOE协议源代码

This is where you can find information on my version of a free PPPoE redirector for Linux. 


Announcements
(1999/10/29) Version 0.3 is released. Some bugs fixed; I added a feature which should fix some MTU problems; the software has been ported to OpenBSD.
(1999/09/28) MTU problems - I have had reports of problems with machines which are behind masquarading firewalls, with the firewall running PPPoE software. In these cases, the upstream transmission of any large packets (i.e., larger than an HTTP request or so) causes strange PPP disconnects and so forth. The cause of this behaviour has been tracked down. All machines which send data to the "real world" must have their MTU (Maximum Transmission Unit) set to a new, smaller value. The default, 1500 bytes (the Ethernet default) is larger than the maximum allowable PPPoE packet size, and it seems that pppd handles the translation of large packets into small ones rather poorly.

To reconfigure the MTUs, do the following:

Under Linux (and, presumably other Unix-workalikes):

# /sbin/ifconfig eth0 mtu 1400 

where eth0 is your Ethernet interface.

Under Windows (95/98; may work under W2K):

Using a registry editor, set

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans\000X\ MaxMTU=1492

(note that the 1492 is a string value).

The 'X' depends on what your interface is.

Under Windows NT (thanks to Shawn Sulma for this) 

Using a registry editor, set 

HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/El90x1/Parameters/ Tcpip/MTU=1492

(note that the 1492 is a DWORD)

The "El90x1" is replaced with your card entry

(1999/09/24) 0.2 released - fixes some portability problems
