SSH / Telnet access to port assigned IP address bring DIGI port selection instead of port console | Digi Passport 32

0 votes
I am using ~30 DIGI console servers
Most of them are Passport 23 but part are CM32
All ports has assigned IP address that allow direct connection to console port of connected device.
I observing access issue accessing devices connected to port 1
They have assigned IP 172.30.X.1 but when I open connection to it I am getting to port selection, in a way if I would connection to Digi itself.

From comparing of exported configuration of working / not working I saw:
\cnf\etc\iptables.save
On working:
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A PREROUTING -d 172.30.13.1 -p tcp -j REDIRECT --to-ports 7001
-A PREROUTING -d 172.30.13.2 -p tcp -j REDIRECT --to-ports 7002

On not working:
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A PREROUTING -d 172.30.12.1 -p tcp -j REDIRECT --to-ports 7000
-A PREROUTING -d 172.30.12.1 -p tcp -j REDIRECT --to-ports 7001
-A PREROUTING -d 172.30.12.2 -p tcp -j REDIRECT --to-ports 7002

How I can remove prerouting rule to port 7000? I did not find it in configuration
