Hi Thord,

I have a slightly different setup, that is working well:


*** On one Raspberry Pi with simh v4.0, I am running DECnet/E V4.1 on 
RSTS 10.1. Node PIRSTS::

The Pi's physical Ethernet eth0 is bridged with a tap device on br0 for 
outside access.

The tap device is assigned to simh's DELQA (set xq type=DELQA; att XQ tap0)


*** On another Raspberry, pydecnet is configured, also on a bridged tap 
device, to connect to the HECnet in area 29 (node ONAPI4::)

in the pydecnet config file are two circuits:

circuit TAP-1 Ethernet --cost 1 tap:tap1 --random-address

circuit MUL-29 Multinet --cost 2 xx.yy.zz.aa:portx:connect

This last line connects me to the HECnet IP-node that expects a 
connection. This is something that you have to agree with your "HECnet 
partner".

Note that I am not using (lib)pcap on any of my simh nodes. bridging the 
physical Ethernet with a tap device makes this unnecessary.
