Hallo,
I wonder how to switch between DHCP and static IP. I found an old post,
and I wonder How this switch can be done with lwip 2.0.2.
I simply call
netifapi_dhcp_release(netif);
netifapi_dhcp_stop(netif);
// set addresses in ipaddr, netmask, gw
netifapi_netif_set_addr(netif, , , );
Sequence number is losted somewhere... I put l2tp->our_ns = l2tp->peer_nr
at the start of pppol2tp_input and now it works without interruptions. But
still no any ping through VPN server from Windows client to the device with
LwIP, only to static ip of the device.

But if server requests with ns=2, nr=4, why LwIP responds with ns=3, nr=3?
nsnr
Data input: c8 02 00 14 d0 b3 00 00 [00 02] [00 04] 80 08 00 00 00 00 00 06
UDP send: c8 02 00 0c 76 c4 00 00 [00 03] [00 03]

No, sorry, it asks. If "Hello" is:
pppol2tp: input packet, len=20, tunnel=53427, session=0, ns=2, nr=4
Data input: c8 02 00 14 d0 b3 00 00 00 02 00 04 80 08 00 00 00 00 00 06
than in pppol2tp_udp_send:
UDP send: c8 02 00 0c 76 c4 00 00 00 03 00 03

Hi Max,
I hope I am not confusing you or making an error here.
As far as I know DHCP client is handled almost completely by LwIP.
You should not worry about timers etc...
I have attached my DHCP task, take a look and I hope this helps...
This code is running with LwIP 1.41
BR,
Noam.
Hallo,
I have some questions about dhcp behaviour:
- Do I have to call the functions dhcp_coarse_tmr() and
dhcp_coarse_tmr() explicitly?
I have this doubt because I have seen that these functions are already
being declared as
timer callbacks in file timeout.c
- if my dhcp server has 10s
