[HECnet] req for assistance: is snmp blocked for some / all ? does it work?

[Paul Koning]

Mine is residential service, that seems to explain the difference.

I just found a Comcast document that confirms port 161 is blocked.  If I can get proxies for interesting Cisco HECnet routers I can consider adding mapper support for that.  I just found a trivial UDP proxy (to a single destination): https://github.com/EtiennePerot/misc-scripts/blob/master/udp-relay.py -- something a bit more complex could allow talking to several destinations, but this one may be good enough.

The unfortunate drawback is that this means I can't use MIB access to supplement the NICE data the mapper uses.
