While full redundancy for both inbound and outbound traffic will require BGP or OSPF, these clients simply wish to join multiple Internet connections (DSL, ISDN or T1) from different providers to gain failover capability should one of their links failed. Without ISPs' support, this type of redundancy only applies to outbound traffic, but that will suffice the clients' requirements already. I searched through the mailing lists and forums but found only very limited resources on how to accomplish such gateway/firewall setup using FreeBSD (or other BSD). It seeems for this type of setup requires running of multiple NAT daemons. Has anyone done something like this? or point me to any HOW-TOs? Thank you all for your input.
