WSK OnReceiveFromEvent

NTDEV
1

Hi all,

I have UDP socket open and bound to a port using the WSK framework and have found that I do not get OnReceiveFrom events unless I first send a UDP packet to the network device that is attempting to send me UDP packets.
Anyone have any ideas as to the source of this behaviour?

Thanks
Nik

Firewall ports opened (or disabled)?

A firewall on your system (or elsewhere) might not ‘open’ the inbound path
until it sees (and keeps seeing) outbound traffic.

Good Luck,

Perfect. Didn’t think of that.

Thanks!
