Direct Access and NLB RRS feed

  • Question

  • I know that in the case of a single UAG box, we need to have 2 consecutive public ip addresses for DA to work.  That's no problem.  But, what if you have an NLB cluster of UAG boxes?  Do we just have the 2 ip addresses as the virtual ip's?  If so, is there any requirement for afinity either for the initial infrastructure tunnel created or the subsequent user tunnel?  Do they both have to map to the same box in the cluster or can they be on different boxes?  Does it make any difference if you are using software (MS) NLB or if you are using hardware NLB?

  • Hi,

    With NLB, you have two IPv4 public consecutives addresses for your VIP but also one IPv4 public addresse as DIP for each UAG array member. So for a two UAG array, you need four IPv4 public addresses. NLB require all addresses to belong to the same subnet.For HLB scenario, you still have 2 ipv4 public addresses for your VIP but you need two IPv4 public addresses for each UAG array member.
