[ILUG] Load Balancing Over 2 Internet connections.

[Owen Connolly]

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  
it...

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...
