Multiple internet connections for Inbound and Outbound Connections
Hello all, (If this is already posted in this mailing list: I''m sorry; I couldn''t find anything.) My problem: I have two ADSL connections, wich I want to use for load balancing and fail-safe. I also have some servers in my DMZ, wich have to be accessible at both external IP''s (preferably). I''ve read the ''Guide to IP Layer Network Administration with Linux'', in particular section ''10.4. Multiple Connections to the Internet''. But the situation I am in, section 10.4.3, isn''t worked out yet. However, I did thought of a solution, and I''d like someone here to ''review'' it, to be more shure I didn''t make a mistake. The solution is a combination of the solutions in sections 10.4.1 and 10.4.2. I''m thinking of a router with 4 NICs, say NIC A-D. A connects to the two ADSL modems, B directly routes traffic to the first modem, C directly routes traffic to the second modem, and D balances traffic to B and C. NIC D is the default gateway for my LAN clients. Traffic for servers in the DMZ will come from NICs B and C (and therefor be replied with the correct external IP). Would this solution work? Maybe there is an other (less ugly) way? What will the performance of this setup be? If someone would comment on this, I''d be very gratefull. Thanks in advance, Jurrie Overgoor -- _____________________________________________________________________ Snel en voordelig ADSL nu voor iedereen bereikbaar.
