(the design attached)
i would like to implement TWO SMG physical appliances as below :
1- one SMG is Scanner only and the second one is Control center & scanner
2- will use inbound & outbound email for both SMG
3- Two physical interfaces on each SMG eth0 & eth1
3- will add a smart route on microsfot Edge Server to forward outbound email traffic to SMG hostname and will use DNS round robin to have a loadbalance for the two SMG.
4- for inbound traffic will create two MX record with same preference.
My Questions :
A- my above points follow the best practices ?
B- is it ok to have eth0 & eth1 in same subnet ? ex. eth0 (inbound) 10.10.10.5 & eth1(outbound) 10.10.10.6
C- any recommendation ?
