Asaf, Cannot ?... The changes in function is limited. The code uses ip4_addr_t instead of struct ip_addr and some defines for IPV6 or 4

I find that LwIP 2.02 Is better and has smaller footprint. Good luck, Noam W. From: lwip-users [mailto:lwip-users-bounces+noam=silrd....@nongnu.org] On Behalf Of Asaf Manasse Sent: Wednesday, June 21, 2017 1:18 PM To: lwip-users@nongnu.org<mailto:lwip-users@nongnu.org> Subject: [lwip-users] internet over PPP and NAT issue LWIP team hallo, I am trying to establish Access Point product based on Marvell MW302 WiFi MCU, using the SDK provided by Marvell. Marvell SDK implement IP Stack using LWIP version 1.4.X ( last commit : 88a57dc98d9793d74f8e1c52729b50188d5a0b4f ) , integrated with wifi. I have established to implement PPPOS over USB to 3G modem. These 2 network interfaces (PPP and wlan) are bridged using LWIP NAT implementation of Company called RT-Thread (taken from https://github.com/RT-Thread/rt-thread/tree/master/components/net/lwip_nat , I have a permission from RT-Thread to use there code ). at this point we have a internet connection to the wifi clients but with connectivity issues: 1. connection is not stable (from test I can may be guess it's unstable upload). 2. WireShark log reveals multiple Duplicated ACK and TCP RST. 3. tcp debug print: [3236.092616] : -+-+-+-+-+-+-+-+-+-+-+-+-+-+ tcp_input: flags [3236.096609] : tcp_input: no PCB match found, resetting. [3236.111094] : tcp_rst: seqno 0 ackno 3423651674. 4. pbuf debug print: pbuf_header: failed as xxx < yyy (not enough space for new header size) configurations: * disabled IP_FORWARD. * set PPP MRU to be 1020 (USB connection bottlenech) is there any additional information you need for better understanding of the issue?
