Default Cannot redirect oidentd port 113 to jail

Hey everyone, i have a problem with redirection of oident port 113 to jail. I want to share irssi for users but they connect without static ident. For example "~user@host" instead "users@host". Whey try from host, works vell. Where could be problem ?

My /etc/pf.conf


################ Translation 
### NAT and Redirection rules are first match ###

 nat pass on em0 from $NET_JAIL to any -> $IP_PUB
 rdr pass on em0 proto tcp from any to $IP_PUB port $PORT_JAIL -> $IP_JAIL
Thanks for all advices.

I am not sure whether the following is applicable to your setup

In a thread on the official FreeBSD forums, the problem was that the connection was initiated locally and not remotely. A local test connection did not work, but doing ir remotely worked. See https://forums.freebsd.org/viewtopic.php?&t=32139

But I don't understand why you need identd to work. When I was using irssi, I used to block incoming port 113 requests and instructed pf to send a TCP reset as answer. That way the IRC server knew that identd was not enabled.
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
