Just wondering how others perform this task when setting up an anonymous relay connector using the powershell command to allow anonymous relaying (the most restricive of the two methods - ie not setting it as externally secured).
The two IP addresses need to be set on the same subnet (eg 192.168.0.1 and 192.168.0.2). Problem is as follows:
- If you give the server a second NIC with the new IP address this isn't best practice as both NICs will be on the same subnet. if you disable netbios on the second NIC is this supported for an Exchange set up though?
- Second option is to set a second IP address on the primary NIC. This would result in two DNS entries for the CAS server in DNS though unless you disable automatic DNS registration on the NIC.
What method do people use to have two DNS aliases for Exchange? MAIL points to the normal receive connector and RELAY will point to the relay connector. Do people just set the externally secured option and not bother with the more restrictive method which requires you to link the IP address to a receive connector rather than leaving it at "Use all available IP addresses"?
