Hello
We've noticed an issue with RST ACK sequence number. It is +1 compared to ACK
received. This causes long delays in reopening new connection.
This is the test setup:
1. PC
2. Switch
3. Device with LwIP
PC opens a TCP connection to device and they start to exchange data.
Hello
Is it possible to add external MIBs (for example LLDP MIB) to LwIP's SNMP
implementation?
I've been checking the LwIP code (1.4.1) for the private MIB implementation,
but I got the idea that it is only possible to add stuff under "internet
.1.3.6.1" or have I misunderstood?
I have notic
for unused ports?
This came up in one certification process (they see it as a problem).

Esa Hill

efore skip the RST?
I forgot to say that we have a list of open ports and we will drop all IPv4
packets in Ethernet driver layer if we don't have the destination port open.
That is why there are no RST responses to the other ports. This is been done
just to save resources.

ble in this port"?
Anyway I'm not making such modifications unless I really have to.

check
when there is open UDP socket.
I could fix this issue there by checking the protocol too. Then there is no
need to touch LwIP. Thank you for this idea :)

Yes :)
