I thought something like this: [ISP] | | ----------------- Office [ADSL] | | [FreeBSD Box] | | | | | | | | [A][B][C][D] where A, B, C, D all have their own routable IPs. So according to what you said, FreeBSD would need to establish a separate PPPoE session for each of the computers A, B, C and D, provided the ISP supports multiple PPPoE sessions over the single ADSL line? I need to know if this configuration is possible, so I will know what to ask the ISP sales and support people. So far they haven't been very helpful.
