In article <1269338285.441561246827349956.JavaMail.root@sz0128a.westchester.pa.mail.comcast.net> you write: >ok, so if i use nat, i can ping and telnet to the bsd machine that is hosting >the vm. on the client, ipconfig -all returns an ethernet adapter with an ip >address of 10.0.2.15, and a gateway of 10.0.2.2.

This might help: http://www.virtualbox.org/manual/UserManual.html#networking-nat (I haven't tried nat portforward on FreeBSD vbox myself yet but I see no reason why it shouldn't work. And in nat mode 10.0.2.2 in the guest is redirected to 127.1 on the host and the guest _should_ be able to talk to outside hosts, just ping doesn't work...) Oh and btw nat mode works basically the same as slirp did in the old days, i.e. translating (in this case) guest packets into host socket calls and back. (which also is the reason ping doesn't work since it uses icmp which would need raw sockets which only work as root.) Good luck, Juergen
