portsnap does not work without direct connection to the Internet

[Victor Sudakov]

Colleagues,

There seems to be a problem with portsnap when it has no direct
connection to the Internet. I have a box which has access to the
Internet only from one of its secondary IP addresses. What I end up
all the time with is a partial failure:

[root at fw ~] printenv | grep -i pro
[root at fw ~]
[root at fw ~] rm -rf /var/db/portsnap/ ; mkdir /var/db/portsnap/
K[root at fw ~] env FETCH_BIND_ADDRESS=217.29.84.225 portsnap fetch

[root at fw ~]


So it does download some things but not all things.  Can it be the
case that some parts of portsnap do not use fetch(1) to download
things?

There seems to be a related problem with freebsd-update, at least it
fails when HTTP_PROXY is configured with login and password, like 
"setenv HTTP_PROXY http://user:pass@my.proxy.ru:3128".
