Hi Sylvain,
Thanks for your help. Yes, you're right. I was using the wrong PPPoS input
path. I should have used pppos_input_tcpip() instead of pppos_input() in my
circumstance.
Regards,
Charles

Hi Sylvain,
I try to use PPP server on AT91SAM7x chip and it failed authentication (both
sides using PAP). Here's the debug message from a Linux (PPP client) followed
by lwIP PPP debug message. Interesting thing is the PPP authentication failure
also causes the whole lwIP stack stop working. I

NO_SYS = 0. I am using freeRTOS. I increased both main lwIP thread and my PPP
application thread stack size from 200 to 500 and problem not solved. The
message after enabling PRINTPKT_SUPPORT is as following:
ppp phase changed[1]: phase=0..
ppp_listen[1]..
ppp phase changed[1]:
Sylvain,
I observed similar messages. I think VJ is in effect in my test.

Hi Sylvain,
I applied the patch and it seems everything is working. However, I don't know
much about VJ support,
so I don't know if the PPP server and my gateway device have actually
negotiated to use VJ at all.
Please tell me how to check VJ is in effect. Is there any specific debug
options
Sylvain,
I applied the new patch, but the following statement always cause Data Abort
exception run-time error. No matter I set ETH_PAD_SIZE to 0 or 2. The good
thing is my compiler doesn't generate any error message for the new patch.

Great, the latest patch works. Thank you very much.

Hi Sylvain,
Thank you for your reply. I really appreciate your help. The below are a few
comments and more observations.
Well, ip_forward() should call netif-output(), which in our case is
ppp_netif_output_ip4(), could you first check that ?
Sorry, I may confuse you about which direction the
Sylvain,
It seems the patch makes things worse - PPP connection couldn’t build-up
anymore. Below is the complete log message after applying the patch. It seems
the code stalled at very early stage.
*** FreeRTOS Demo Started! ***
netif_set_ipaddr: netif addrnetif: IP address of interface set
Below is more debug information and hope it's helpful for fixing the problem.
Regarding the code stalled at early stage, that's hardware related. I am using
ARM7 (AT91SAM7 to be specific), so the data alignment is 4 and PBUF_LINK_HLEN
is 14 by default, so I replaced all PBUF_LINK_HLEN in the

Good news, I got it work with your patch plus the replacement of

Hi Sylvain,
I try to get IP forwarding work between two interfaces - Ethernet and PPP. So
far, I can see it works in one direction, i.e., Packets from Ethernet can be
forward to PPP, but it seems lwIP stack silently drop the packets in the
opposite direction, i.e., from PPP to Ethernet. Can
Hi Sylvain,
Here's my scenario:
I am developing a gateway between Ethernet and PPP using ppp-new branch. The
gateway device has one Ethernet port(IP 192.168.0.50, i.e., 0x3200a8c0) and one
PPP port (IP 192.168.1.105, i.e., 0x6901a8c0). For testing purpose, I connected
the Ethernet port to a
Sylvain,
The Ethernet and PPP interfaces don't share the same subnet, actually they are
in different subnet, i.e., Ethernet uses subnet 192.168.0.0 with netmask
255.255.255.0 while PPP uses subnet 192.168.1.0 with netmask 255.255.255.0.
Any problem with the above settings?
Charles
You're right. It was a typo.

Hi Sylvain,
I think in your post
http://lists.nongnu.org/archive/html/lwip-users/2013-06/msg00011.html, you gave
some code snippet showing how to use ppp-new in user's application. I believe
that snippet is used in a non-threaded application, am I right?
Can you give an example application
Sylvain,
I try to compile ppp-new and my compiler(Keil) gave compiling errors like this:
.\lwip-1.3.0\src\include\netif/ppp/vj.h(110): error: #20: identifier u_short
is undefined
.\lwip-1.3.0\src\include\netif/ppp/vj.h(111): error: #20: identifier u_char
is undefined
Hi Sylvain,
Don't be fooled by the folder name lwip-1.3.0. Actually the whole src folder
under it contains the ppp-new's src folder. I just kept lwip1.3.0 folder name
to minimize the change to Keil project files.

The compiler log is in the attached file. Keil uVision use ARMCC compiler,
here's the command line options for compiling:

Hi there,
I am new to the lwIP community and try to use lwIP v1.4.1 to implement a
gateway between an Ethernet interface and PPP on ATM91SAM7x. I found a port
(with lwIP 1.3) in FreeRTOS community contributions and migrated to lwIP 1.4.1.
It works fine with the Ethernet part, but the port
