It's not exactly the same but if you want something you can somewhat refer to, the Living Computer Museum has an AT&T 3B2/1000 online running SVR3: https://wiki.livingcomputers.org/doku.php?id=at_t_3b2_1000-70

I seem to recall being able to connect in the past but I can't seem to get in via the guest account right now.  In any case, if you can get connected over there that might be a valuable source of configuration examples to study.

I have a 3b2/400 emulator running Unix V r3 fine,
but I have two questions.

Unix is set up with IP 10.0.2.15

I can telnet off it great but can not telnet into it. Is there a step I
am missing?

In the sim ini file I have set:

set NI enabled
attach NI nat:

Someone suggested:

attach nat:tcp=2323:10.0.2.15:23,tcp=2121:10.0.2.15:21

but that did not work.

This is what I get at boot time:

NAT args:
NAT network setup:
gateway =10.0.2.2/24(255.255.255.0)
DNS =10.0.2.3
dhcp_start =10.0.2.15
Protocol[State] FD Source Address Port Dest. Address Port RecvQ SendQ

Thanks,
