I dont have the configuration with me right now (and it is probably gone since the site using it does not have adsl anymore) however the most fun configuration I did was something like that: two adsl links, two OpenBSD firewalls, using carp for failover. each firewall had connections to _both_ adsl modems, so that they can balance outgoing stuff. The load balancing was done using multipath routing (route -multi). The carp was used on the inner interface. So if carp was master, I would bring UP both pppoe interfaces if one of the pppoe connections went down, I would adjust routing to route over the remaining session etc. In order to make failover work smoothly, I matched the MAC addresses on the corresponding outer interfaces of each firewall so that they can see the same pppoe sessions, and built the kernel with PPPOE_TERM_UNKNOWN_SESSIONS Can -- In theory, there is no difference between theory and practice. But, in practice, there is.
