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!

Hi David,
I have most of my setups with OPTIONS pings (upstream carrier and myself).
If I want to fade out a Kamailio I set the option response to an not 200
value (like 603 or whatever) and my internal and the external system didn't
bring in new invites but leave the currently running out.
You can use cfg values for that or some kind of htable with value or so.
Maybe an idea for your setup.

Thanks Karsten,
That won’t work for me with TLS clients, which is what I’m trying to do.
I’m making a PR with a new tcp param.
Thanks!
