machine and just import it's outside interface onto the inside
machines. For example, this is how we configure our outside interface.
# second ethernet to serve the outside IP
echo starting ether 1 to the outside
bind -b '#l1' /net.alt
bind -b '#I1' /net.alt
ip/ipconfig -x /net.alt -g 204.178.31.1 ether /net.alt/ether1 204.178.31.2 255.255.255.0
ndb/cs -x /net.alt -f /lib/ndb/external
ndb/dns -sx /net.alt -f /lib/ndb/external
aux/listen -d /rc/bin/service.alt -t /rc/bin/service.alt.auth /net.alt/tcp
aux/listen -d /rc/bin/service.alt /net.alt/il
Then you can import that interface to inside machines.
import achille /net.alt /net.alt
