Are those IP addresses intended for machines on your LAN?

If so, I have an idea (though I am not a network guru and never did this before): what if adding the surplus IP addresses to em0, as IP aliases, then redirect them to your internal machines by natd?

You can add IP aliases in rc.conf like this:
ifconfig_em0_alias0="inet 192.168.0.1 netmask 255.255.255.255"
For redirection, see man natd.

Sorry for the doublepost, I struggle a lot with my new installation of opera browser, and, I did not have time to fix it.

So, if you will use all those those IP addresses for a web server on a machine, then you need to use IP aliases. You can add any number of IP aliases to a NIC (alias0, alias1, alias2, etc.).
Do it as I mentioned above.

Thats ok

So each one has to look like this

ifconfig_em0_alias0="inet 65.125.xxxx netmask 255.255.255.255"
ifconfig_em0_alias0="inet 65.125.xxxx netmask 255.255.255.255"
ifconfig_em0_alias0="inet 65.125xxx netmask 255.255.255.255"

etc etc?

No, do it like this:

ifconfig_em0_alias0="inet 192.168.0.1 netmask 255.255.255.255"
ifconfig_em0_alias1="inet 192.168.0.2 netmask 255.255.255.255"
ifconfig_em0_alias2="inet 192.168.0.3 netmask 255.255.255.255"

Just one last note:
If those IP addresses were your real IP addresses, then you had better edit your previous posts and change them to some other arbitrary IP address. (I do the same with my posts in this thread).

For security reasons, it is not a good practice to post your actual IP address at any forum.
