Hello all,
Following up on this, I made a patch (attached), could you please review and apply if it looks ok? The patch creates a new core cfg variable which, if set, will reject any incoming NEW tcp connection attempt, so we can use this to gracefully drain kamailio.
Thanks & Regards,

Hello all,
Is there any way of actually rejecting (RST) NEW tcp connection attempts, while allowing the ongoing ones to finish naturally?
I’m thinking maybe we can add this feature?

Hello,
what about e.g. just using something like iptables, nftables etc..?
iptables -A INPUT -p tcp --syn --destination-port <port> -j REJECT --reject-with icmp-host-prohibited
Cheers,
Henning

Hey, Henning, yeah I thought about that, but thought that maybe there was a better way to do it via Kamailio
Thanks!
