WAAS Inline Adaper and Microsoft NLB (ISA Server Array)

Hi

I would like to place a waas device with 4-port inline adapter  between a MS ISA Firewall and the LAN switches. The ISA are unfortunately forming an array and using NLB which causes the switches to do unknown unicast flooding.

            / Switch A --------------- LAN0   WAN0  ------------ ISA1 ------------- Switch C ---------- Router A

LAN -- |            |                               WAAS                        Array                        |       HSRP     |

            \ Switch B --------------- LAN1   WAN1  ------------ ISA2 ------------- Switch D ---------- Router B

Will the WAAS get problems since it is seen all the traffic on both inline groups? Is this setup possible?

kind regards

Tobias
