Tushar, Service providers do not assign public IPs to modems. They are usually behind an ISP gateway. You need to talk to your ISP if public IP is needed. Rest everything looks fine. Regards, Ajay Bhargav From: Tushar Patel Hello, I am using GSM LTE Modem from Quectel EC21. I am having problem pinging the device after it has successfully acquired the IP address. The modem works fine on Windows machine when I try to use dial up connection. I am doing something wrong or my settings are not correct Below is the log and config file. #define PPP_SUPPORT 1 /* Set > 0 for PPP */ #define NUM_PPP 1 /* Max PPP sessions. */ #define PPPOS_SUPPORT 1 #define PAP_SUPPORT 1 /* Set > 0 for PAP. */ #define CHAP_SUPPORT 1 /* Set > 0 for CHAP. */ #define MSCHAP_SUPPORT 0 /* Set > 0 for MSCHAP */ #define CBCP_SUPPORT 0 /* Set > 0 for CBCP (NOT FUNCTIONAL!) */ #define CCP_SUPPORT 0 /* Set > 0 for CCP */ #define VJ_SUPPORT 1 /* Set > 0 for VJ header compression. */ #define MD5_SUPPORT 1 /* Set > 0 for MD5 (see also CHAP) */ #define PPP_DEBUG LWIP_DBG_ON #define PRINTPKT_SUPPORT 1 8250:tNET>0.0.0.0.255.255terface pp IPce 8250:tNET>ppp phase changed[0]: phase=0 8250:tNET>ppp_connect[0]: holdoff=0 8250:tNET>ppp phase changed[0]: phase=3 8250:tNET>pppos_connect: unit 0: connecting 8250:tNET>ppp_start[0] 8250:tNET>ppp phase changed[0]: phase=6 8250:tNET>pppos_send_config[0]: out_accm=FF FF FF FF 8250:tNET>ppp_send_config[0] 8250:tNET>pppos_recv_config[0]: in_accm=FF FF FF FF 8250:tNET>ppp_recv_config[0] 8250:tNET> CHAP=1 CHAP_MD5=1s: 8250:tNET>sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x448fe8ac> <pcomp> <accomp>] 8255:tNET>pppos_write[0]: len=24 8255:tNET>ppp_start[0]: finished 8265:TCP/IP>pppos_input[0]: got 99 bytes 8266:TCP/IP>rcvd [LCP ConfReq id=0x0 <asyncmap 0x0> <auth chap MD5> <magic 0x8ce22304> <pcomp> <accomp>] 8267:TCP/IP>sent [LCP ConfAck id=0x0 <asyncmap 0x0> <auth chap MD5> <magic 0x8ce22304> <pcomp> <accomp>] 8272:TCP/IP>pppos_write[0]: len=29 8273:TCP/IP>rcvd [LCP ConfAck id=0x1 <asyncmap 0x0> <magic 0x448fe8ac> <pcomp> <accomp>] 8273:TCP/IP>netif_set_mtu[0]: mtu=1500 8273:TCP/IP>pppos_send_config[0]: out_accm=0 0 0 0 8274:TCP/IP>ppp_send_config[0] 8274:TCP/IP>pppos_recv_config[0]: in_accm=0 0 0 0 8274:TCP/IP>ppp_recv_config[0] 8274:TCP/IP>ppp phase changed[0]: phase=7 8278:TCP/IP>pppos_input[0]: got 63 bytes 8279:TCP/IP>rcvd [LCP DiscReq id=0x1 magic=0x8ce22304] 8280:TCP/IP>rcvd [CHAP Challenge id=0x1 <7c74c0e1f0fb5cc034cd7687a7c0de25>, name = "UMTS_CHAP_SRVR"] 8280:TCP/IP>No CHAP secret found for authenticating us to UMTS_CHAP_SRVR 8281:TCP/IP>sent [CHAP Response id=0x1 <6a749ee30ba8736e7be0a62fb618565f>, name = ""] 8284:TCP/IP>pppos_write[0]: len=25 8286:TCP/IP>pppos_input[0]: got 10 bytes 8286:TCP/IP>rcvd [CHAP Success id=0x1 ""] 8286:TCP/IP>CHAP authentication succeeded 8287:TCP/IP>CHAP authentication succeeded 8287:TCP/IP>ppp phase changed[0]: phase=9 8287:TCP/IP>sent [IPCP ConfReq id=0x1 <compress VJ 0f 01> <addr 0.0.0.0>] 8290:TCP/IP>pppos_write[0]: len=20 8307:TCP/IP>pppos_input[0]: got 26 bytes 8307:TCP/IP>rcvd [IPCP ConfReq id=0x0] 8308:TCP/IP>sent [IPCP ConfNak id=0x0 <addr 0.0.0.0>] 8310:TCP/IP>pppos_write[0]: len=14 8310:TCP/IP>rcvd [IPCP ConfRej id=0x1 <compress VJ 0f 01>] 8311:TCP/IP>sent [IPCP ConfReq id=0x2 <addr 0.0.0.0>] 8313:TCP/IP>pppos_write[0]: len=14 8313:TCP/IP>pppos_input[0]: got 10 bytes 8314:TCP/IP>rcvd [IPCP ConfReq id=0x1] 8314:TCP/IP>sent [IPCP ConfAck id=0x1] 8315:TCP/IP>pppos_write[0]: len=8 8316:TCP/IP>pppos_input[0]: got 16 bytes 8316:TCP/IP>rcvd [IPCP ConfNak id=0x2 <addr 10.200.45.187>] 8317:TCP/IP>sent [IPCP ConfReq id=0x3 <addr 10.200.45.187>] 8319:TCP/IP>pppos_write[0]: len=14 8321:TCP/IP>pppos_input[0]: got 16 bytes 8321:TCP/IP>rcvd [IPCP ConfAck id=0x3 <addr 10.200.45.187>] 8322:TCP/IP>Could not determine remote IP address: defaulting to 10.64.64.64 8322:TCP/IP>sifvjcomp[0]: VJ compress enable=0 slot=0 max slot=0 8322:TCP/IP>netif: netmask of interface pp set to 255.255.255.255 8323:TCP/IP>netif: GW address of interface pp set to 10.64.64.64 8323:TCP/IP>netif_set_ipaddr: netif address being changed 8323:TCP/IP>netif: IP address of interface pp set to 10.200.45.187 8323:TCP/IP>sifup[0]: err_code=0 ppp_link_status_cb: PPPERR_NONE our_ip4addr = 10.200.45.187 his_ipaddr = 10.64.64.64 netmask = 255.255.255.255 dns1 = 0.0.0.0 dns2 = 0.0.0.0 8325:TCP/IP>local IP address 10.200.45.187 8325:TCP/IP>remote IP address 10.64.64.64 8325:TCP/IP>ppp phase changed[0]: phase=10 Regards, Tushar |
