I have > heard of extremely expensive cisco solutions to do similar to this, but I used ipfw's "fwd" with "prob" to max out 2 x 2mbit lines back when v4.8/9/10 was released . It takes some effort to get Just Right (tm) but it can be done. Tips: Do not use keep-state on the fwd rules (infact you might want to try to avoid ipfw for the actual filtering), NAT or multiple providers breaks things too. I had to avoid using fast-forwarding but this might be better now. > we've already forked out enough on hardware and connections so we're > trying to do this part a bit cheaper. Oh haven't we all, that's why we started saving up for the luxury of testing configurations before rolling them, even with something so comfortably flexible as FreeBSD. :P~~ -- Sten Daniel Sørsdal [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFDzhWdMvOF8Nb1apsRApYVAJwL9jZwGEQcn6LgXXNan8U3JSh01ACfWKl0 LTT92fQocNvPyI3PhbOnBmc= =EEEF -----END PGP SIGNATURE-----
