To work behind a NAT box you'll need to be able to pass SNMP and GRE
through to the DECbrouter. If you can do that you'll be golden.
GRE doesn't run over a port, it's a Layer 4 (transport) protocol.
Oooo, how I hate it when people try to make the IP stack line up with the OSI model... :-)
They are *incompatible*.
SNMP is 161.
That is port 161 in both UDP and TCP.
Sorry, I just felt like nitpicking today. Grumpy I guess. Call me an old fart. :-)

The email address is just where you want notification emails sent so
your normal email is probably appropriate.
The emails that are sent can also be copy and pasted into the router in
the event that SNMP doesn't work.

I was going to have a go at this today, but thinking about it I am not
sure this can work at DEC Legacy or even here at home because it would
always be behind NAT. Can we make this work with NAT? What ports would
you need?
Nevertheless I have it configured with DECnet and I have entered the
two SNMP commands below (I used the public community name, not sure
if that is right because I know very little about SNMP).
The information you wanted was:
Your external IP Addres: 86.4.69.74
Your external FQDN: jarratt.dyndns.org <http://jarratt.dyndns.org>
Is this a dynamic IP: yes
The DECnet area at this location: 5
The source interface on your router: Ethernet0
The email address you want updates sent to: rob at jarratt.me.uk
<mailto:rob at jarratt.me.uk> (not sure if this is what you mean, this
goes to my regular email address, are we talking about some email
capability in the router?)
The snmp community from the above directions: public
I hope that is the information you need.
Regards
Rob

I won't be home until the end of the week, I will try it this weekend.

Ok, 5 lines. :)
first you need to enable DECnet routing:
decnet routing X.Y (where X.Y is the DECnet address you want to give it)
decnet node-type area
Then you need to add this to the interface that talks to your DECnet LAN
segment:
decnet cost 10
Then you need to allow my config tool to talk to your router:
access-list 10 permit 37.59.44.141
snmp-server community <community name> RW 10
Then you just need to get me all that info I asked for and we should be
good.
The machine running the config tool is down right now so I'm in no
hurry. :)
