KS ITS running under pdp10-ks Cannot do TELNET, FTP, or SUPDUP #2223

I'm running a renamed DB ITS under pdp10-ks. I can access KS via SUPDUP over chaosnet, but cannot access it over TCP/IP. My pdp10-ks script has:

set imp enabled
set imp host=192.168.1.100
set imp ip=172.16.0.4/24
set imp gw=172.16.0.2
at imp nat:gateway=172.16.0.2,network=172.16.0.0/24,tcp=4023:172.16.0.4:23,tcp=4021:172.16.0.4:21,tcp=4095:172.16.0.4:95

I access telnet from my host via telnet 127.0.0.1 4023 and get no response (no ITS herald). I see nothing in PEEK that shows that the connection has been established.

I access FTP from my host via telnet 127.0.0.1 4021 (for testing) and never see the FTP herald.

I access SUPDUP from my host via supdup 127.0.0.1 4095 and never get an ITS herald.

(Note I can do all these with effectively the same config for my KA instance using pdp10-ka).

(Note: I can do TELNET and SUPDUP using TCP/IP to my KL instance using pdp10-kl, but not FTP).

Is this specific to pdp10-ks, but works with pdp10-ka and kl?

I don't know how to use TCP/IP with anything but KLH10.

Yes, specific to pdp10-is.

pdp10-kl has an issue with FTP, but otherwise tcp/ip works.
