I suspect this may have to do with subnet numbers (the "c" part of your
internet addresses) not matching properly with chaos addresses. See the
section "Mapping an Internet Address into a Chaos Address" in the Symbolics
documentation. It explains how the high-order bits of the chaos address
are mapped into the third field ("c" in your description) of the internet
address. Good luck.
That section is just a suggestion for a useful convention to follow. No
software expects or assumes any relationship between Chaos and Internet
Never say "never". At least no Symbolics software seems to expect such
a relationship. On CISCO gateways exists a (rather minimal) Chaosnet
router which states that it expects such a relationship in order to
forward chaos packets between subnets.
I learnt that when we switched half of GMD's lisp machines onto a
physical subnet last year and didn't get them to recognize their
server on the other side due to not obeying to said convention.
I'd be happy to agree that *enforcing* such a convention in a router
isn't the best thing to do.
