I am n ot sure what you are doing but I also havd dsl router with 4
ports and 4 machines (2 are wireless). My hosts file is as follows:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1		localhost.localdomain localhost
192.168.1.100		vulcan vulcan.gateway.2wire.net
192.168.1.101		saturn saturn.gateway.2wire.net
192.168.1.65		cyrus cyrus.gateway.2wire.net

And I can do : ssh vulcan from saturn without problem. Is that what you
want to do?
