Currently have a dual wan setup both connections with the same ISP who has provided me 8x2 public IP's. I would like to create redundancy so my ms sbs server and IP PBX (trixbox) have public IP's and will continue to work even if either wan connection goes down.
for since the sbs server is a domain controller, it needs an internal IP address is it possible to set the correct routing and static NAT's?
my trixbox needs to use the same IP at all times and I would like to use smtp directly to the sbs server and pop3 collection from my web host as backup. so mx1 is the ms exchange server and mx2 is my hosting company.
both wan addresses wan1:1.1.1.72-79 & wan2:1.1.1.88. netgear prosafe router
