At risk of being beaten senseless by some purists, you should be able
to rig inbound service fail-over by using Dynamic DNS.
Any half-decent firewall should allow you to have 2 WAN interfaces.
If you then configure your NAT cleverly, you can put your outbound
generic surfing traffic out one interface and leave the other for
Inbound services/VPN traffic/etc...
AFAIK smoothwall does the above, but it's a while since I looked at
Alternatively you could use 2 gateways with 2 OSPF yokies (Tired,
words not work proper) internally, done properly you could have a
very cool fully resilient solution.
Or else just use rainwall which will allow you to have 2 boxes with
shared Virtual IPs and true load-balancing... I've used this
commercially with Symantec SGS boxes (yes they are linux!) and it
works a treat, but I haven't tried it with any freebies... Their
generic version of rainconnect can be used with IPTables/Chains...
Hope there's something useful in my ramblings...
