Hello everybody,
i have a question about IPCP protocol. During etablishement phase, lwip and GPRS modem exchange IP, DNS1 and DNS2 address.
So i wonder what is "our adress IP" and "his adress IP" ?
Normally, GPRS modem give us an address IP which is (i think) "our" address IP. But i dont know what is "his address IP".

We can see it in "ppp.c" / "sifaddr()" or :

typedef struct ipcp_options {
  u32_t   ouraddr, hisaddr;  /* Addresses in NETWORK BYTE ORDER */
  u32_t   dnsaddr[2];        /* Primary and secondary MS DNS entries */
  u32_t   winsaddr[2];       /* Primary and secondary MS WINS entries */
} ipcp_options;

Thank you
